x=months

so erica: 200+75x

darrell: 350+50x

make them equal:

200+75x=350+50x

get x on one side.

125x=550

500/125=x

x=4.4

You can change the denominators so they are alike. $\frac{16}{40} + \frac{15}{40} = \frac{31}{40}$
Not sure how there can be two possible answers unless you're mentioning the decimal form:
.775

Find the value of x.<br> 105°/15x

Natalija [7]

$\text{The two angles are supplementary, so their measures add up to 180 degrees.}$

$~~~~~~15x+105 = 180\\\\\implies 15x = 180 -105\\\\\implies 15x = 75\\\\\implies x =\dfrac{75}{15}\\\\\implies x = 5$

(-9)-[15divided by 5]^3•6

Aleks04 [339]

Answer:

-171

Step-by-step explanation:

Applying PEMDAS (order of operations),

We open the parenthesis first;

-9 - ( $\frac{15}{5}$ )³ × 6

-9 - 3³ × 6

We work on multiplication next;

-9 - 27 × 6 = -9 - 162

finally we do subtraction to get;

-9 - 162 = -171
