A cable 90.6 meters long is cut into two pieces so that one piece is 37.2 meters longer than the other. Find the length of each piece of cable.

Answers

Answer:

53.4

Step-by-step explanation:

It said cut that means subtraction also in different length. So you subtract 90.6-37.2=53.4

Answer:

26.7 meters and 63.9 meters

Step-by-step explanation:

37.2 + 2x = 90.6

-37.2 -37.2

2x = 53.4

53.4 ÷ 2 = 26.7 meters

26.7 + 37.2 = 63.9 meters

63.9 + 26.7 = 90.6 meters

Hope that helps.

Use the Distributive Property and simplify the expression.9 + 4(2x – 1) + 8

I got 9?

Answers

The distributive property: a(b - c) = ab - ac

9 + 4(2x - 1) + 8 = 9 + 4·2x - 4·1 + 8 = 9 + 8x - 4 + 8 = 8x +13

9 + 4 (2x - 1) + 8
Expand the bracket

=> 9 + (4 * 2x) + (4 * -1) + 8
simplify the bracket

9 + 8x - 4 + 8
make the expression equal to 0 and solve

9 + 8x - 4 + 8 = 0
9 - 4 + 8 + 8x = 0
13 + 8x = 0

8x = -13

x = $(- 13)/(8)$
