Given:
John had to pay a combined electric and gas bill $150.
The electric portion of the bill was $90.
To find:
The ratio of money spent on electric to that on gas.
Solution:
Let x be the amount of gas bill.
The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,



The gas portion of the bill was $60.
The ratio of money spent on electric to that on gas is:




Therefore, the ratio of money spent on electric to that on gas is 3:2.
Answer:
a
Step-by-step explanation:
Answer:
Simplifying
y = 1000X
Solving
y = 1000X
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 1000X
Step-by-step explanation:
Answer:
Firstly you need to put the equation in form of. y =ax+b
Let us do it
We have
2x-2y=18
-2y=18-2x
-y=(18) /2 - (2x)/2
-y =9-x
Mutiply by - to remove it beside y
Y=-9+x
Which is y=x-9
Slope =a=1
Yintercept=b=-9
Answer:
it simple a+b=ab
Step-by-step explanation:
bc=bc+c
