Rick has 12 cups of glue

Step-by-step explanation:

If AC=18x-7,find the x. Round to the nearest hundredth if necessary AB=7x+29 BC=30

Margaret [11]

Answer:

$x=6$

Step-by-step explanation:

AC = AB + BC

$18x-7=(7x+29)+30$

$18x-7=7x+29+30$

$18x-7=7x+59$

Add 7 to both sides:

$18x-7+7=7x+59+7$

$18x=7x+66$

Subtract 7x from both sides:

$11x=66$

Divide both sides by 11:

$\frac{11x}{11}=\frac{66}{11}$

$x=6$
