Divide 36 books into two groups so the ratio is 5 to 7. (Use the double number line strategy)

lutik1710 [3]

A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)

So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.

P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)

he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation

soldi70 [24.7K]

The equation that represents x when solved is $x=\frac{y-8}{1.5}$

Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:

y = 1.5x + 8

We are to express x in terms of "y"

$y = 1.5x + 8$

Subtract 8 from both sides

$y -8= 1.5x + 8-8\\y-8 = 1.5x\\Swap\\1.5x = y - 8$

Divide both sides by 1.5

$\frac{1.x}{1.5}= \frac{y-8}{1.5} \\x=\frac{y-8}{1.5} \\$

Hence the equation that represents x when solved is $x=\frac{y-8}{1.5}$

Check the picture below.

well, its radius didn't change, anyhow, you know what to check out.
