Renee, susan, and Martha share the cost to rent a vacation house for a week

1 answer:

No, Martha is incorrect.
To find out how much Martha must pay, she must add up .4 + .35. It equals = .75. So Martha must pay the rest of it, so 1 - .75 = .25.
So Martha pays 1/4 of the cost.

1) value of x =60

2) value of x = 3

Step-by-step explanation:

We need to use cross products to solve the proportions of x.

$1.\,\, \frac{3}{5}= \frac{x}{100}$

Solving:

$\frac{3}{5}= \frac{x}{100}\\Cross\,\,multiply\,\,:\\5x=3*100\\5x=300\\x=\frac{300}{5}\\x=60$

So, value of x =60

$2.\,\,\frac{x}{8}=\frac{7.5}{20}$

$\frac{x}{8}=\frac{7.5}{20} \\20x=7.5*8\\20x=60\\x=\frac{60}{20}\\ x=3$

So, value of x = 3
