Answer:

The equation can be used to find <em>x</em>, the number of gallons that should be evaporated is: \frac{13.5}{90-x}=\frac{25}{100}.

Step-by-step explanation:

Consider the provided information.

Let us consider <em>x</em> is the amount of water Carlon plans to evaporate.

Thus, 90 - <em>x</em> is the amount of water after being evaporated.

The amount of salt is 15% of 90 gallons which can be written as:

S=90\times{0.15}

S=13.5

The percentage of salt will be:

\%S=\frac{13.5}{90-x}=\frac{25}{100}

Hence, the equation can be used to find <em>x</em>, the number of gallons that should be evaporated is: \frac{13.5}{90-x}=\frac{25}{100}.

What proportion results in the equation 9m=10n
Serhud [2]
Give the equation 9m = 10n

Dividing both sides by 9n, we have
\frac{9m}{9n} = \frac{10n}{9n}  \\  \\  \frac{m}{n} = \frac{10}{9}

Therefore, the <span>proportion that results in the equation 9m = 10n is
\frac{m}{n}=\frac{10}{9}

Mrs. Smythe is twice as old as her daughter Samantha. Ten years ago the sum of their ages was 46 years. How old is Mrs. Smythe?
Fynjy0 [20]
Mrs. Smythe = x
Daughter = y

x = 2y
(x - 10) + (y - 10) = 46
x - 10 + y - 10 = 46
x + y - 20 = 46
x + y = 66
Put 2y in for x
2y + y = 66
3y = 66
y = 66/3
y = 22

The daughter is 22
The mother = 44
