Answer:
£110
Step-by-step explanation:
We know how much time it takes for a boiler and a radiator, and we need to know how much it will cost for 1 boiler and 4 radiators. We have an initial cost of £30, and since hes doing a boiler - which we know takes an hour - we can already add £20 for a start of £50.
Now, there are 4 radiators, that take 45 minutes each. We need to use this equation:
We divide by 60 because there are 60 minutes in an hour, and he charges by hour. So:
Now, to find out how much to charge, we need to figure out how much to add to the £50. Since it's £20 an hour, and it takes 3 hours to do the 4 radiators, we need to multiply:
Now we add our totals for a grand total of...
Answer:45+60=15x+15x
Step 1: Simplify both sides of the equation.
45+60=15x+15x
(45+60)=(15x+15x)(Combine Like Terms)
105=30x
105=30x
Step 2: Flip the equation.
30x=105
Step 3: Divide both sides by 30.
30x/30= 105/30
x= 7/2
Answer:
x= 7/2

Answer: The cost for the month is $240.
Step-by-step explanation:
Since we have given that
Cost for the two i.e Aveeno and her boyfriend = $40
They were charged 6 times in a month.
As we know that times stands for multiplication.
So, we need to find the cost for the month, where we multiply 6 with $40 to get the amount for the whole month.
So, the amount for the month would be
Hence, the cost for the month is $240.
There are three negative signs so the product will be a negative.
