Divide 33 photos into two groups so the ratio is 4 to 7

Levart [38]

33 photos in a 4x to 7x ratio

4x + 7x = 33
11x = 33
x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Note:
<span>a(b) = ab = a x b = a times b</span>

maxonik [38]

Answer:

$11\ gallons$

Step-by-step explanation:

we know that

Haley's car gets at least $18$ miles per gallon

so

by proportion

Find the minimum number of gallons she'll need for a trip that is $200$ miles

$\frac{1}{18}\frac{gallon}{miles} =\frac{x}{200}\frac{gallon}{miles}\\ \\x=200/18\\ \\x= 11.11\ gallons$

then convert meters to centimeters (just move the decimal place two places to the right)
answer is 1,435 cm
