Answer:
<u>Christine needs to drive 250 miles for the two plans to cost the same</u>
Step-by-step explanation:
For answering the question correctly and helping Christine, we will use the following equation:
x = number of miles driven
Cost of the first plan = 0.60x
Cost of the second plan = 50 + 0.40x
How many miles would Christine need to drive for the two plans to cost the same?
Cost of the first plan = Cost of the second plan
0.60x = 50 + 0.40x
0.60x - 0.40x = 50 (Subtracting 0.40x at both sides)
0.20x = 50
x = 50/0.2
x = 250 miles driven
<u>Christine needs to drive 250 miles for the two plans to cost the same.</u>
Answer: The expression has 3 terms
The expression represents the sum of 9z,4y, and 3x
The expression represents y multiplied by 4 plus x multiplied by 3 plus z multiplied by 9
The second term has a coefficient of 4
Step-by-step explanation:
8x - 3 = -19
8x = - 19 + 3
8x = -16
x = -16/8
x = -2
answer: the number is negative 2
