Take care to read through all the important information's that are given in the question. Based on those information's the answer to the question can be easily deduced.
Initial price of gas = $125
Increased price of gas = $150
Amount of increase in the gas bill per month = (150 - 125) dollars
= 25 dollars
Percentage increase in the gas bill per month = (25/125) * 100
= 100/5 percent
= 20 percent
So the percentage of increase in the gas bill per month is 20%. I hope the procedure is clear enough for you to understand.
Answer:
There is no solution to this equation
Step-by-step explanation:
answer
x=6, y=-2
explanation
-2x + 8 = y -------equ 1
3x - y = 22 -------equ 2
u can use any of the simultaneous equation method
using elimination method
rearrange first from -------equ 1
-2x+8=y
-y-2x=-8
multiple through by -1
y+2x=8 -------equ 3
rearrange first from -------equ 2
3x-y=22
-y+3=22 ------equ 4
equate 3 and 4, adding them together
y+2x=8 -------equ 3
-y+3=22 ------equ 4
0+5x=30
5x=30
x=6------equ 5
replace 6 for x in any equation
using -------equ 3
y+2x=8
y+2(5)=8
y+10=8
y=8-10
y=-2
Your answer is b hope this helps
