For 12, you would do 90=4x+42, and 48=4x, and x=12
for 15, you would do 90=8x+66, and 24=8x, and x=3
for 18, you would do 90=3x+57, and 33=3x, and x=11

In the diagram, if WA = 8, AX = 5, and YA = 10, then the length of YZ is

Zinaida [17]

Answer:

Step-by-step explanation:

WA times AX = YA x YZ

8x5=40

because they have to equal each other we just have to divide 40 by 10

If six times a number is decreased by fourteen, the result is 124. What is the number

denis23 [38]

Answer:

$\large\boxed{23}$

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is $\large\boxed{23}$

Hope this helps :)
