Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 30. In other words, x plus y equals 30 and can be written as equation A:
x + y = 30
The difference between x and y is 20. In other words, x minus y equals 20 and can be written as equation B:
x - y = 20
Now solve equation B for x to get the revised equation B:
x - y = 20
x = 20 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 30
20 + y + y = 30
20 + 2y = 30
2y = 10
y = 5
Now we know y is 5. Which means that we can substitute y for 5 in equation A and solve for x:
x + y = 30
x + 5 = 30
X = 25
Summary: The sum of two numbers is 30 and their difference is 20. What are the two numbers? Answer: 25 and 5 as proven here:
Sum: 25 + 5 = 30
Difference: 25 - 5 = 20

Answer:
y = 5/4x + 9
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
m = 5/4
Random point (-8, -1)
y = 5/4x + b
Step 2: Find y-intercept b
-1 = 5/4(-8) + b
-1 = -10 + b
b = 9
Step 3: Write linear equation
y = 5/4x + 9
Is 6,364 a reasonable product for 706×45
Answer:
I don't think so because I tried it and that's what I got
Step-by-step explanation:
Answer:
No, it is not. A reasonable product is 31,770.
Step-by-step explanation:
Ever heard of a calculator? It's way faster.
45 x 100 = 4,500
4,500 x 7 = 31,500
45 x 6 = 270
31,500 + 270 = 31,770

The EPA estimated that in 2013, the average amount of garbage produced in the United States was 4.4 pounds per person per day. At that rate, how long would it take YOUR family to produce a ton of garbage? (A ton is 2,000 pounds.)
Answer:
my family has six people so 75.76 days
Step-by-step explanation:
multiply 4.4 with the number of people in your family, then divide 2000 by that number
example:
4.4 x 6= 26.4
2000/26.4 = 75.75 which rounds to 75.76

Answer:
C (and D)
Step-by-step explanation:
The multiplication property of equality says the value of the variable is unchanged when both sides of the equation are multiplied by the same value.
In A, no property of equality is involved. The two equations are for different lines.
In B, the subtraction property of equality is used to subtract 9 from both sides of the equation.
In C, the multiplication property of equality is used to multiply both sides of the equation by 3.
In D, the division property of equality is used to divide both sides of the equation by 5. (This is equivalent to using the multiplication property to multiply both sides of the equation by 1/5.)

If you're allowed one choice, the best selection is C. If multiple choices are allowed, both C and D are correct answers.

Suppose a hawk can fly 78 miles in 3 hours. An owl can fly 99 miles in 4 hours. Which raptor can fly faster and by how much?
Answer:
The Hawk can fly faster
Step-by-step explanation:
First, take 78/3 that will give you the miles per hours the hawk flys.
78/3 = 26 miles/ per hour
Then, do the same for the owl.
99/4 = 24.75 miles an hour.
To find out how much faster the hawk in than the owl suntract the owls miles per hour from the hawks miles per hour.
24.75 - 26 = 1.25 miles faster
Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. What does the constant of proportionality, 42, represent in this situation? The constant of proportionality is 42.
Answer:
y=42h or h=y/42
Step-by-step explanation:
The constant would be the number of yards of yarn required for each hat .
You are playing a video game. For each diamond you collect, you earn 100 points. You also earn 75 bonus points by completing the level in less than 2 minutes. You need to earn more than 1575 points to continue on to the next level. Write and solve an inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Answer:
The data that we have is:
For each diamond, you earn 100 points.
If you complete the level in less than 2 minutes, you earn a bonus of 75 points.
You want to earn more than 1575 points.
Now, assuming that you want to write and solve n inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Because you end in less than 2 minutes, then you have the bonus of 75 points.
Then the number of points as a function of d, the number of diamonds, is:
P(d) = 100*d + 75
And you want that:
P(d) > 1575
100*d + 75 > 1575
Now we can solve this for d.
100d > 1575 - 75
100d > 1500
d > 1500/100
d > 15
You must collect more than 15 diamonds.
Given the function f(x) = 3x-7, which of the following represents f -1(x)?
-3x+7
Step-by-step explanation:
The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.
f -1(x)= -1(3x-7)
f -1(x)= -3x+7
Lynda regularly works a 40-hour work week and earns $16.00 per hour.
She receives time-and-a-half pay for each hour of overtime she works.
Last week she worked 43 hours.
a. What is her regular gross pay?
b. What is her hourly overtime rate?
c. What was her overtime pay?
d. What was her total pay for the week?
Answer:
Step-by-step explanation:
gross pay = 640
hourly overtime rate= 24
Overtime pay= 72
Total pay for the week= 712
Her regular gross pay is 640. the hourly overtime rate is 24. Overtime pay= 72 and Total pay for the week= 712
What is Regular gross pay ?Regular gross pay is that pay which the person earn on daily basis or it is a fixed amount which he gets after completing a month.
Here, We have to find out the regular gross pay which includes the daily earning of a person.
Lynda regularly works a 40-hour work week and earns $16.00 per hour.
So, her regular gross pay = number of hours × rate per hour
= 40 × $16
= $640
Hence, the gross pay = 640
Her regular gross pay is 640. the hourly overtime rate is 24. Overtime pay= 72 and Total pay for the week= 712

Lin has a drawing with an area of 20 in²
If she increases all the sides by a scale factor of 4, what will the new area be?
Answer:
320 in²
Step-by-step explanation:
Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:
Square of scale factor of the side = scale factor of area
4² = scale factor of area
16 = scale factor of area
Multiply the original area by 16
20 × 16 = 320 in²

there are 35 students in art class and 57 students in dance class. Find the number of students who are either in art class or in dance class
Answer:
hope it helps you
Step-by-step explanation:
Let
A be the set of students in art class
B be the set of students in dance class
n(A) = 35
n(B) = 57
a) When 2 classes meet at different hours and n(A ∩ B) = 12 we have:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = 35 + 57 - 12 = 80
b) When two classes meet at the same hour we have A∩B = ∅ that is n(A ∩ B) = 0 and
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = n(A) + n(B) = 35 + 57 = 92
