Answer:
one solution
Step-by-step explanation:
Answer:
He received 10 dimes and 15 quarters.
Step-by-step explanation:
Dimes = $0.10
Quarters = $0.25
Variable x = dimes
Variable y = quarters
Create a pair of linear equations:
0.10x + 0.25y = 4.75
x + y = 25
Isolate any variable, using an equation of your choice:
x + y = 25
x = 25 - y
Plug in this new value of x into the other equation:
0.10(25 - y) + 0.25y = 4.75
Use the distributive property:
2.5 - 0.10y + 0.25y = 4.75
Combine like terms:
2.5 + 0.15y = 4.75
Isolate variable y:
0.15y = 2.25
y = 15
Plug in the value of y into any equation:
x + y = 25
x + 15 = 25
Isolate variable x:
x = 10
Answer: <em>33 square feet</em>
Step-by-step explanation:
<em>First, let's take the area of the rectangle shown here which is 6ft long and 4ft wide</em>
<em>6x4=24</em>
<em>Now let's take the area of the square which is 3ft long and 3ft wide</em>
<em>3x3=9</em>
<em>Now add 24 and 9 for the total area</em>
<em>24+9=</em><em>33 square feet</em>
