Answer:

x < 3/2 month

x = number of months

Planet fitness:

25 + 10x < 10 + 20x

25 - 10 < 20x - 10x

15 < 10x

x < 15/10

x < 3/2 month

It is less expensive to join planet when the number of months is less than 3/2 months

BigorU [14]

Answer:

y = - 13, y = 13

Step-by-step explanation:

Given

y² = 169 ( take the square root of both sides )

y = ± \sqrt{169} = ± 13

Since 13 × 13 = 169 and - 13 × - 13 = 169

Are the two ratios that make up a proportion<br> always, sometimes, or never equivalent
masya89 [10]

Answer:

Always

Step-by-step explanation:

In mathematics, when we say that two ratios form a proportion, we mean that the two ratios are equal.

Ex: Ratios and Proportions - Proportions - In Depth. A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

A proportion is two ratios which have been set equal to each other; a proportion is an equation that can be solved. When I say that a proportion is two ratios that are equal to each other, I mean this in the sense of two fractions being equal to each other. For instance, 105 equals 21 .
