The blue container holds 4/3 of the amount red container can hold. Maggie measures out 80 cubic inches of sand by filling the blue container once and the red container twice. What is the volume in cubic inches of the red container?

B = 4R/3

(4/3)R + 2R = 80

(4/3)R + (6/3)R = 80

(10/3)R = 80

10R = 240

R = 24 cubic inches.

1/x + 1/2x + 1/3x

factor out 1/x

1/x (1 + 1/2 + 1/3)

1/x (6/6 + 3/6 + 2/6)

1/x (11/6)

11/6x

Asked by Sdsf from Sicklerville, NJ

4(3 - 2x) = -44

use distributive law of multiplication by multiplying 4 and 3 and 4 and -2x:

12 -8x = -44

-44 -12 = -8x

-56 = -8x

x = 7

#### Abby's investment at 14% earned the same interest as Steve's which was \$1500 less but at 18%. How much did steve invest?

How do i set up this question?

+ more- less
Asked by Mathalina from Louisville, KY

let x be Abby's investment

so, Steve's investment is x - 1500

so:

.14x = .18 * (x - 1500)

figure out the rest.
