They will spend $152.881 because when you divide the total amount of miels by the 20 miels you will get 52.9 miels than you are going to multiply the 52.9 miels by the amount of money for one gallon u get $152.881 dollars for 52.9 times you put in gas on the car.
7+3x-12x=3x+1
We will first make all the numbers which have x in go to the left.
So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.
Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.
So now it is much easier to figure out.
-12x=-6
So If Hannah weighed 7.2 lb at birth during the six months that are shown on the table hanna puts on 8.7 during those six months so if we’re estimating what her weight will be at her one year visit
8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6
Answer: I estimate she will weigh 24.6lb at her one year visit
