explain how to use thedistributive property to find an expression that is equivalent to 20 + 16
Answer: 4(5 + 4)
Step-by-step explanation: Both 16 and 20 are multiples of 4, so factor out 4 and leave the remaining factors in parentheses
4*5 + 4*4 becomes
4(5 + 4) add inside parentheses
4(9) multiply to check
4 × 36
same as adding 20 + 16 = 36

Identify the scale factor used to graph the image below
Answer:
[tex]Scale = \frac{2}{3}[/tex]
Step-by-step explanation:
To solve this question, I'll use the coordinates of SV and S'V' as points of reference.
From the attachment:
[tex]S = (3,6)[/tex]
[tex]V = (15,3)[/tex]
[tex]S' = (2,4)[/tex]
[tex]V' = (10,2)[/tex]
First, calculate distance SV
Distance formula is:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
For SV:
[tex]d_1 = \sqrt{(15 - 3)^2 + (3 - 6)^2}[/tex]
[tex]d_1 = \sqrt{(12)^2 + (-3)^2}[/tex]
[tex]d_1 = \sqrt{144 + 9}[/tex]
[tex]d_1 = \sqrt{153}[/tex]
For S'V'
[tex]d_2 = \sqrt{(10 - 2)^2 + (2 - 4)^2}[/tex]
[tex]d_2 = \sqrt{64 + 4}[/tex]
[tex]d_2 = \sqrt{68}[/tex]
The scale factor is then calculated using:
[tex]Scale = \frac{S'V'}{SV}[/tex]
[tex]Scale = \frac{d_2}{d_1}[/tex]
Substitute values of d1 and d2
[tex]Scale = \frac{\sqrt{68}}{\sqrt{153}}[/tex]
[tex]Scale = \sqrt{\frac{68}{153}}[/tex]
[tex]Scale = \sqrt{\frac{1}{2.25}}[/tex]
[tex]Scale = \frac{1}{1.5}[/tex]
Express as a proper fraction
[tex]Scale = \frac{1*2}{1.5*2}[/tex]
[tex]Scale = \frac{2}{3}[/tex]

Simplify the expression. -5/8(-3/8-1/4)
Answer:
25/64
Step-by-step explanation:
To get this answer, first you need to use the distributive property:
(-3/8)(-5/8) - (1/4)(-5/8)
Next, multiply:
15/64 - (-5/32)
Change the negative signs into a positive sign:
15/64 + 5/32
Multiply 5/32 by 2 on both top and bottom:
15/64 + (5)(2)/(32)(2)
You will then get:
15/64 + 10/64
Now, add the numerators. You will get:
25/64
This is your answer. I hope it helped!
Four times the sum of a number and 3 is the same as the sum of two times the number and 8. Find the number.
Answer:
Step-by-step explanation:
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4

Find
(a) the value of q in radians
(b) the area of the shaded region in cm²
Answer:
(a) 1.18
(b) 99.71
Step-by-step explanation:
to know the value of q in degrees we can use cosine of q
[tex]\cos (q) = \frac{OR}{OQ}\\\\\cos (q) = \frac{5}{13}\\\\q = \cos^{-1}(\frac{5}{13})\\\\q \approx 67.38[/tex]
now to radians
the formula is
[tex]x\times\frac{2\pi}{360}\\\\[/tex]
with x the degrees
[tex]67.38\times \frac{2\pi}{360}\\\\=\frac{67.38\pi}{180}\\\\\approx 0.374\pi\\\\\approx 1.18[/tex]
so the measure of angle q is 1.18 radians
so now for part b
[tex]A = \frac{r^2 \alpha }{2}\\\\[/tex]
with [tex]\alpha[/tex] being the central angle in radians
for degrees is the following
[tex]A = \frac{\theta}{360}\times \pi r^2[/tex]
so we have
[tex]A = \frac{13^2 (1.18)}{2}\\\\A = 99.71[/tex]cm^2

Given:
The graph of set of ordered pairs.
To find:
The domain of the set of number.
Solution:
Domain is the set of input values or x-values.
From the given graph it is clear that the set of ordered pair is:
{(1,2), (2,4), (3,1), (4,6), (5,4), (6,5)}
Here, the x-values are 1, 2, 3, 4, 5, 6. So, the domain is the set of these values.
Domain = {1, 2, 3, 4, 5, 6}

Two friends went to buy fireworks to celebrate new years eves. One friend bought 6 rockets and 11 bombs for $36.50. The other one bought 14 rockets and 8 bombs for $41. What was the cost of one rocket? (solve with system of equations)
Answer:
Cost of one rocket = $1.5
Step-by-step explanation:
Given:
6 rockets and 11 bombs cost = $36.50
14 rockets and 8 bombs cost = $41
Find:
Cost of one rocket
Computation:
Cost of one rocket = x
Cost of one bomb = y
So,
6x + 11y = 36.50.....eq1
14x + 8y = 41......eq2
From eq1
y = [36.50 - 6x]/11
From eq2
14x + 8y = 41
14x + 8[36.50 - 6x]/11 = 41
x = 1.5
Cost of one rocket = $1.5

Help. Algebra rjsffjdnsifvnswkfnc
Answer:
No x-intercept/Zero
Step-by-step explanation:
f(x)=3x(3/4)x-4
To find x-intercept/zero, substitute f(x)=0
0=3x(3/4)x-4
To raise a fraction to a power, raise the numerator and denominator to that power
0=3x 3 x-4/4 x-4
Calculate the product
0=3 x-3/4 x-4
Since the right-hand side is always positive, the statement is false for any value of x
Since there is no solution for f(x)=0, there is no x-intercept/Zero
The total cost of a ticket and the online fee for one ticket is $32.25.Let f represent the cost of ordering each ticket online.Write an equation that could be used to find the cost of ordering each ticket online.
Answer:
The equation is f = z - x
Step-by-step explanation:
The equation is
Given that
The total cost + online fee for one ticket is $32.25
Let us assume f be the cost of ordering each ticket online
Cost of each ticket be x = $24.95
And, the total cost = z = $32.25
Now the equation would be
x + f = z
So for f it would be
f = z - x
URGENT: Sally has five more quarters than dimes. Sally has a total of $9.30. Find the number of dimes and quarters that sally has. (Explain your answer)
Answer:
36 Quarters and 3 dimes
Step-by-step explanation:
4 x 9 = 36
10 x 3 + 30
Answer:
28 quarters and 23 dimes
Step-by-step explanation:
q = d + 5
.25a +.1d = 9.30
.25(d+5) +.1d = 9.30
.25d + 1.25 +.1d = 9.30
.35d = 8.05
d = 23
23 + 5 = 28
q = 28
I need help with this problem..
Answer:
3y - x = 3
Step-by-step explanation:
The slope intercept form of the equation is expression is y = mx+c
m is the slope
c is the y inercept
From the graph
c = 1
Using the coordinates (-3, 0) and (0, 1)
m = 1-0/0-(-3)
m = 1/3
Get the required equation
y = 1/3x + 1
Multiply through by 3
3y = x + 3
3y - x = 3
Hence the required equation is 3y - x = 3
Complete the equation.

Victor wants to earn at least $1,500 this month in commission. What is the minimum amount he needs to sell in order to earn $1,500 if he earns a 6.5% commission on everything he sells? Round your answer to the nearest dollar.
Answer:
$23,077
Step-by-step explanation:
Let the minimum amount you want to earn be represented as x
Therefore
6.5% of x = $1,500
6.5/100 × x = $1500
6.5x/100 = $1500
Cross Multiply
6.5x = $1500 × 100
x = $1500 × 100/6.5
x = $23076.923077
Approximately to the nearest dollar= $23,077
Therefore, the minimum amount he needs to sell in order to earn $1,500 if he earns a 6.5% commission on everything he sells is $23,077
what is x+3= - (-x+ ___ )
Answer:
-3
Step-by-step explanation:
Note the right side of the equation. There is a negative sign outside of the parenthesis. Distribute the negative sign to all terms within the parenthesis:
x + 3 = - (-x + __)
x + 3 = x - ___
Note:
1) When multiplying a negative and positive together, the answer will be negative
2) When multiplying a negative and negative together, the answer will be positive:
x + 3 = x - ___
Note the equal sign, this means that the two side of the equation must equal. This means that the only answer choice is -3:
x + 3 = x - (-3)
x + 3 = x + 3 (True)

Lynns mom is baking treats for lynns birthday party. She has 12 eggs to use for this purpose. A batch requires two eggs and a batch of brownies requires 3 eggs. Write an inequality to match this solution.
Answer: 2x +3y ≤ 12
Step-by-step explanation:
Given: Lynn's mom has 12 eggs to use for this purpose..
i.e. she can use maximum 12 eggs.
A batch of cookies requires two eggs and a batch of brownies requires 3 eggs.
Let x= Number of batches of cookies , y= Number of batches of brownies
Then, 2x +3y ≤ 12 (maximum eggs = 12)
hence, the required inequality : 2x +3y ≤ 12
