Answer:
Cost of driving Jenna's car is $0.293 per mile when the price of gas is $3.23 per gallon.
Step-by-step explanation:
Expression given in the question is not correct, it is actually
Since expression that represents Jenna's cost to drive her car for work is
Where J = cost of driving Jenna's car
g = cost of gas
We have to find the cost of driving Jenna's car when the price of gas is $3.23 per gallons.
Now we plug in the value of g = $3.23 per gallon in the given expression.
= 0.1468 + 0.146
= 0.2928
≈ $0.293 per mile
Therefore, cost of driving Jenna's car is $0.293 per mile when the price of gas is $3.23 per gallon.
Answer:
6°
Step-by-step explanation:
Let
the supplementary angles be 7x and 8x so,
7x+8x=180 ,15x=180 ,x=180/15 ,x=12
smaller angle=7x=7×12=84°
complement of 84°=90°-84°=6°
Answer:
3
Step-by-step explanation:
To find 12.5% of 2 dozen
We convert 2 dozen into a number which would be:
2×1 dozen (1 dozen = 12)
2×12=24
12.5% of 24 will be
10% of 24 will be 24÷10=2.4
2.5% will be 1/4 of 10%
2.5% = 2.4÷4
2.5%=0.6
12.5%=0.6+2.4
12.5%=3

Answer:
You don't really need to do it, but it helps you keep things more organized and easier to follow. Imagine if you're doing some multi-variable equation,
2a + 5b + 4d + 3c + b + a + 2d
that looks like a mess, it'll be easier to look at if you put all the similar variables next to each others like this:
a + 2a + b + 5b + 3c + 2d + 4d
(a + 2a) + (b + 5b) + 3c + (2d + 4d)
now you can add them up much easier.
