8 - 10 = 2
-2 ≠ 2
Hey there!
“Simplify (1 + 3)2 – 10 = 2”
IN ORDER FOR YOU TO SOLVE FOR THIS EQUATION YOU HAVE TO DO PEMDAS
- (P)arentheses
- (E)xponents
- (M)ultiplication
- (D)ivsion
- (A)ddition
- (S)ubtraction
(1 + 3)2 – 10 = 2
(1 + 3) = 4
4(2) – 10
4(2) = 8
8 – 10 = –2
Answer: –2 ≠ 2 so this makes this statement FALSE
Good luck on your assignment and enjoy your day!

Simplify:
1. ½(2r + 4) - ¼(16 - 8r)
2. (8x - 3) - (2x + 6)
3. (2 - 7y) - 3(y - 9)
4. 2(3x - 4) - (2x - 5)
Step-by-step explanation:
1. ½(2r + 4) - ¼(16 - 8r)=3r-2
2. (8x - 3) - (2x + 6)=6x-9
3. (2 - 7y) - 3(y - 9)=-10y+29

What is the value of x? Four-fifths x minus StartFraction 1 Over 10 Endfraction = StartFraction 3 Over 10 EndFraction One-fourth StartFraction 8 Over 25 EndFraction Two-fifths One-half
Answer:
1/2Step-by-step explanation:
Given the expression
4/5 x - 1/10 = 3/10
We are to find the value of x
4/5 x = 3/10 + 1/10
4/5 x = 4/10
Cross multiply
4x * 10 = 5 * 4
40x = 20
x = 20/40
x = 1/2
The value of x is 1/2
Answer:
Its 1/2 :)

question is which function has a greater y-intercept?
answers:
function 1
function 2
The same function gave the same y-intercept
Answer:
The same function gave the same y-intercept
Step-by-step explanation:
Y-intercept can be calculated when x is 0. This is easy to figure out the table because it already gave us the value of y when x was 0, which was 3.
For the first function, we know that it has a y-intercept of 3.
For the second function, getting the y-intercept is very easy because you can look at the value of y at x=0. We can physically see that it is 3, meaning that they both have the same y-intercept.

Answer:
-212
Step-by-step explanation:
an = a1 + (n-1)d, so
a52 = a1 + 51d
a1= - 8
d = -4 ( because you take away 4 every time)
so a52 = -8 + 51(-4) = -212

Answer:
Part a y=10.99+1.25x
Part B 14.74
Answer:
Part A) 10.99 + x = y
Part B) 14.74$
Step-by-step explanation:
In part A, you add the number of toppings to the pizza. Making the expression: Pizza Cost + Topping = Total Amount.
In part B, you do 1.25*3 = 3.75 (Cost of 3 toppings) + 10.99 (Cost of the pizza) = 14.74$

Answer:
x < -10/3 OR x > 20/3
Step-by-step explanation:
|5 - 3x| - 3 > 12
|5 - 3x| > 15
since it's absolute value, you have 2 scenarios to solve:
1) 5 - 3x > 15
-3x > 10
x < -10/3 (when dividing or multiplying by a negative, switch the symbol)
2) -(5 - 3x) > 15
-5 + 3x > 15
3x > 20
x > 20/3

The circumference of the larger circle is approximately 22 meters and the circumference of the smaller circle is approximately 11 meters. Use a proportion to find the approximate diameter of the smaller circle. If necessary, round your estimate to the nearest tenth.
Answer: approximately 3.5 meters.
Step-by-step explanation:
Given: Circumference of the smaller circle is approximately 11 meters.
Circumference of a circle = [tex]\pi d[/tex] , where d= diameter.
Ratio of circumference to diameter = [tex]\pi[/tex]
As per given,
[tex]\pi=\dfrac{11}{d}\\\\\Rightarrow\ d=\dfrac{11}{\pi}\\\\\Rightarrow\ d=\dfrac{11\times7}{22}\ \ \ [\pi=\dfrac{22}7]\\\\\Rightarrow\ d=\dfrac72=3.5\ meters[/tex]
Hence, the diameter of the smaller circle is approximately 3.5 meters.
Multiply. (5x + 7)2
A. 25x2 + 35x + 49
B. 25x2 – 70x + 49
C. 25x2 + 70x + thing
D. 25x2 + 49
Answer:
(5x + 7)² = 25x² + 70x + 49 ⇒ C
Step-by-step explanation:
The steps of solving the square binomial: (ax + b)²
1. (ax + b)² = (ax + b)(ax + b)
2. (ax + b)(ax + b) = (ax × ax) + (ax × b) + (b × ax) + (b × b) = a²x² + abx + abx + b²
3. Add the like terms ⇒ a²x² + (abx + abx) + b² = a²x² + 2abx + b²
Then (ax + b)² = a²x² + 2abx + b²
Let us use the same steps to solve the question
∵ (5x + 7)² = (5x + 7)(5x + 7)
∴ (5x + 7)(5x + 7) = (5x)(5x) + (5x)(7) + (7)(5x) + (7)(7)
∴ (5x + 7)(5x + 7) = 25x² + 35x + 35x + 49
→ Add the like terms
∵ 25x² + 35x + 35x + 49 = 25x² + (35x + 35x) + 49 = 25x² + 70x + 49
∴ (5x + 7)(5x + 7) = 25x² + 70x + 49
→ Then equate (5x + 7)² by the right side above
∴ (5x + 7)² = 25x² + 70x + 49

4x - 5y = 9
- 6x + 5y = -11
Answer:
Therefore, x = 1 and y = -1 .
Step-by-step explanation:
The steps are :
[tex]4x - 5y = 9 - - - (1)[/tex]
[tex] - 6x + 5y = - 11 - - - (2)[/tex]
[tex](1) + (2)[/tex]
[tex]4x + ( - 6x) = 9 + ( - 11)[/tex]
[tex] - 2x = - 2[/tex]
[tex]x = 1[/tex]
[tex]sub \: x = 1 \: into \: (2)[/tex]
[tex](2)⇒[/tex]
[tex] - 6(1) + 5y = - 11[/tex]
[tex] - 6 + 5y = - 11[/tex]
[tex]5y = - 11 + 6[/tex]
[tex]5y = -5[/tex]
[tex]y = -1 [/tex]
Answer:
I hope it work
Step-by-step explanation:
4x-5y=9 -6x+5y=-11adding both the equations
4x-5y=9
-6x+5y=-11
-2x+0y=-2
-2x=-2
Now divide both sides by -2
-2/-2 x= -2/-2
x=1Now putt the value of x in one of above equation to get value of y4(1)-5y=9now solve this-5y=9-4-5y=5divide -5 to both sidesy= -1These are he required value of x and yplease Brain-list the answer if u like it thanks...A ticket at a movie theater costs $9.25.

A store pays $ 56 for a cell phone. The store marks the price at 20%. What is the quantity of the mark?
Answer:
The quantity of the mark is $11.20
Step-by-step explanation:
Given that:
Amount paid by store for cell phone = $56
The store marks the price at 20%.
Quantity of the mark = 20% of 56
Quantity of the mark = [tex]\frac{20}{100}*56[/tex]
Quantity of the mark = 0.2 * 56
Quantity of the mark = $11.20
Hence,
The quantity of the mark is $11.20
