Help? 11 3/4 is the quotient of a number y and 6 1/4

Answers

Answer:

y divided by 6 1/4 = 11 3/4

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

y divided by 25/4 = 47/4

Next, multiply both sides by 25/4:

y divided by 25/4 x 25/4 = 47/4 x 25/4

The 25/4's on the left side of the equation cancel each other out, leaving you with:

y = 47/4 x 25/4

Multiply 47 x 25 and keep the same denominator:

y = 1,175/4

Divide and:

y = 293 3/4

The accompanying diagram shows two triangles. Which proportion could be used to solve for x ?

Answers

Answer:
A) 32/x=12/15

Explanation:
When we compare 32/x, we’re looking the ratio between the two side lengths on the first triangle. When we compare 12/15, we’re looking at the ratio between the two side lengths on the second triangle. These ratios must be equal to each other since the two triangles are similar, and we can use this to solve for x.

If 72 = 12x, what does x equal?

Answers

Answer:

x=6

Step-by-step explanation:

So, x is our unknown variable. An so you have to ask yourself, what times 12= 72? The answer would be 6, because 12x6=72

The proper way to do it, would be to divide 12/12 so you isolate the variable, and what you do to one side, you do to the other, so divide 72 by 12 and you get 6! Hope this helps!
