Step-by-step explanation:
Because when you and you need don't forget that when you
9(-6x-2)-7(-10x-2)
Simplify, by distributing the 9 and the -7
-54x-18+70x+14
Combine like terms
16x-4 is the simplified expression

Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32

Answer:
The cost of 80 oranges = 480 nairas
Step-by-step explanation:
Given
The cost of 5 oranges = 30 naira
Determine
The cost of 80 oranges
Given that the cost of 5 oranges = 30 naira
so,
Unit rate = 30 nairas / 5 oranges
= 6 nairas per orange
∴ The cost of 1 orange = 6 nairas
As the cost of 1 orange = 6 nairas
Thus,
The cost of 80 oranges = 6 × 80 = 480 nairas
Hence,
The cost of 80 oranges = 480 nairas
