Step-by-step explanation:
Alright, after reading this problem, let’s highlight some key points. Each sweater costs $25, we can write that down as 25x because will represent the amount of sweaters we buy. But we have a shipping fee of $7, so we will +7 to our highlights. And the total money spent was $132.
So far, we have: 25x + 7 = 132
Let’s subtract the 7 from the 132. Now we have: 25x = 125
Then we can divide by 25 on each side, and get x by itself.
X = 5 sweaters.
BONUS: Let’s replace 5 for our x to prove our answer
25(5) + 7 = 132 >>> 125 + 7 = 132 >>> 132 = 132 :D
There you go!! We buy 5 sweaters from American Eagle..!
Answer:
65 sq ft
Step-by-step explanation:
SA(sq pyr) = area of base + 1/2(perimeter of base)x(slant height)
SA = 5² + 1/2(10)(8)
SA = 25 + 40
SA = 65
Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5

Step-by-step explanation:
<u>Step 1: Define Equation</u>
8(2x + 5) = 16x + 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 8: 16x + 40 = 16x + 40
- Subtract 40 on both sides: 16x = 16x
- Divide 16 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ <em>x</em> has an infinite amount of solutions.
