If AC=18x-7,find the x. Round to the nearest hundredth if necessary <br>AB=7x+29 <br>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:

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

$x=6$

PLS help meeeeeeee!!!!!! will mark as BRAINLIEST

We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.

Let us assume that 7 is n% of 30. So we can set a proportion as:

$\frac{n}{100}=\frac{7}{30}$

Let us solve for n.

$\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100$

$n=\frac{7}{3}\cdot 10$

$n=\frac{70}{3}$

$n=23.333$

Therefore, 7 is $23.333\%$ of 30.

What is z equal to ? Please help

MakcuM [25]

The sum of the interior angles of a triangle (half the rhombus in this case) is 180. Because of the properties of a rhombus, z and x will be equal to each other. Therefore, $124 + z + z = 180$ .
$124 + z + z = 180$
$124 + 2z = 180$
$2z = 56$
$z = 28$
Thus, z is equal to 28.
