Solve for x.<br> 79°<br> (8x - 4)<br> -(3x + 17)<br> X=
kolbaska11 [484]

Answer:

X=4.2

Step-by-step explanation:

Simplifying 8x + -4 = 3x + 17 Reorder the terms: -4 + 8x = 3x + 17 Reorder the terms: -4 + 8x = 17 + 3x Solving -4 + 8x = 17 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -4 + 8x + -3x = 17 + 3x + -3x Combine like terms: 8x + -3x = 5x -4 + 5x = 17 + 3x + -3x Combine like terms: 3x + -3x = 0 -4 + 5x = 17 + 0 -4 + 5x = 17 Add '4' to each side of the equation. -4 + 4 + 5x = 17 + 4 Combine like terms: -4 + 4 = 0 0 + 5x = 17 + 4 5x = 17 + 4 Combine like terms: 17 + 4 = 21 5x = 21 Divide each side by '5'. x = 4.2 Simplifying x = 4.2

Hope this helps :)

Pls help me i need to fill in the boxes that dont have anything in them but i aldo need to fill in the one that says "A="​
Temka [501]

Answer:

Area is 20

Perimeter is 24

A= L × W

Step-by-step explanation:

Area is found by multiplying the length by the width, which in this case is 10 × 2 = 20

Perimeter is found by adding all of the sides together, so 2 + 2 + 10 + 10 = 24

A= Legnth × Width or vise versa

grandymaker [24]
12 to 2 is 6:1
24 to 4 is 6:1
32 to 6 is 16:3
48 to 8 is 6:1

So 32 to 6 is the one that isn’t equivalent. :)
