Answer:

c = 45h + 25

Step-by-step explanation:

The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.

c = 45h + 25

How do you write 290 as a decimal
mixas84 [53]

Hello there!

This question super easy to me.

<em>290%= 2.9 that came from in decimal form.</em>

First you had to write 290 as a decimal you can have to divide numerator by the denominator of the fraction. It should 290 as a decimal it equal to 290. 2.9 is the correct answer. Hope this helps! Thank you for posting your question at here on Brainly. -Charlie

Answer:

B)

Step-by-step explanation:

Because it says that Alex wants to spend exactly $30 so you want to have 30 as the total (  = 30 )

and it says 18 plus, you only add 18 one time ( 18 + )

and then it says 0.12 per mile, so you need to do something times 0.12 + 18 and get exactly 30. so you do ( 0.12x ) in this case we're not solving it we're just doing the equation so it's just 0.12x instead of a specific number

Put it all together and you get 18 + 0.12x = 30

Hope this helps dude
