Answer:
8 oranges and
4 bananas
Step-by-step explanation:
Let the number of oranges be A and that of bananas be B
Given she bought oranges and bananas,She bought 12 pieces of fruits
That’s
A + B = 12
Also
Oranges cost = $0.50
Bananas cost = $0.25
She spent a total of $5
That’s
0.50A + 0.25B = 5
We now have two equations
1. A + B = 12
2. 0.50A + 0.25B = 5
Multiply equation 1 by 0.50 and equation 2 by 1 to eliminate A
We have
0.50A + 0.50B = 6
0.50A + 0.25B = 5
Subtract equation two from equation one
0.25B = 1
Divide both sides by 0.25 to isolate B
0.25B/0.25 = 1/0.25
B = 4
Now substitute 4 for B in either equation to get A
Using equation 1, we have
A + B = 12
A + 4 = 12
Subtract 4 from both sides
A + 4 - 4 = 12 - 4
A = 8
Erica bought 8 oranges and 4 bananas
Check
A + B = 12
8 + 4 = 12

Answer:
inches
Step-by-step explanation:
Let the width be x.
Length =
Perimeter = Length + Length + Breadth + Breadth
Perimeter =
Subtract 12 from both sides:
Divide both sides by 4:
(Width)
Length = inches.

Answer:
= -8x +24w +16
Step-by-step explanation:
The factor outside multiplies each term inside parentheses.
-8(x -3w -2) = (-8)(x) +(-8)(-3w) +(-8)(-2)
= -8x +24w +16
