Multiply it by 1/4 because the dimensions are already 1/4
Answer:
17
Step-by-step explanation:
Follow the pattern
Each shaded part measures 75 because half of 30 is 15, so, the half of the rectangle is 150, so if only 1/2 of each part is shaded, 150÷2=75
This is an algebra problem. We let x be the variable for the number of pounds of apples bought, and y be the number of pounds of bananas bought. From the descriptions, the formulas that we can formulate are:
y = 2x --> eqn 1
0.79x + 0.39y = 7.58 --> eqn 2
Substituting eqn 1 to eqn 2:
0.79x + 0.39(2x) = 7.58
Solving for x,
x = 4.828 pounds of apples
y = 2x = 2(4.828) = <em>9.656 pounds of bananas bought</em>
Total number of coins is: 16 + 28 + 32 +4 = 80 coins
He sold 15% of them. "of" means multiply.
80 x 15% is the same as 80 x .15
80 x .15 = 12
He sold 12 coins
