Given:
Number of rows = 3
Number of columns = 6
Number of square boxes = 18
yellow square boxes in the top two rows = 12
Blue square boxes in the first 5 columns = 15
Number of green boxes (shading overlaps) = 10
To find:
The model to show multiplying a fraction by a fraction.
Solution:
2 rows out of 3 are shaded yellow.
Fraction for yellow =
5 columns out of 6 are shaded blue.
Faction for blue =
10 out of 18 squares are green.
Faction for green =
Now,
Therefore, the correct option is D.
Answer:
24 + 4.5b
Step-by-step explanation:
1. Simplify equation to the right by multiplying -3 to whats in the parenthesis
(12 + 7.2b) - 2.7b + 12
2. Combine like terms.
24 + 4.5b
Answer:
30
Step-by-step explanation:
do parenthesis
then exponents
then multiply or divide (left to right')
then add or subtract (left to right)

3x + -1y = 12
Solving
3x + -1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
3x + -1y + y = 12 + y
Combine like terms: -1y + y = 0
3x + 0 = 12 + y
3x = 12 + y
Divide each side by '3'.
x = 4 + 0.3333333333y
Simplifying
x = 4 + 0.3333333333y</span>
