The area for that shape should be 28 because 20+8=28! Hope this helps.
Answer:
$30
Step-by-step explanation:
Multiply $7.50 by 4 (Him and his friends) and you get a sum of $30
Each of them have 2.50 left
Answer:
50 and 10
Step-by-step explanation:
x+4x+10=y
y is 60
x+4x+10=60
5x+10=60
5x=50
x=10
or
10*4=40
40+10=50
50+10=60
Answer:
Answer is E hope this helps :)
Step-by-step explanation:
Answer:
The two linear equation
x + y = 19.... Equation 1
0.55x + 0.75y = 12.65... Equation 2
Nedra purchased
9 Apples and 11 Oranges
Step-by-step explanation:
Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?
Let the number of apples be represented by x
The number of oranges by represented by y.
Hence,
Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,
Hence:
x + y = 19..... Equation 1
x = 19 - y
$0.55 × x + $0.75 × y = $12.65
0.55x + 0.75y = 12.65.....Equation 2
Hence: we substitute 19 - y for x in Equation 2
0.55(19 - y) + 0.75y = 12.65
10.45 - 0.55y + 0.75y = 12.65
-0.55y+ 0.75y = 12.65 - 10.45
0.20y = 2.2
y = 2.2/0.20
y = 11 oranges
x = 19 - y
x = 19 - 11
x = 8 Apples
