Complete Question
Sophie pays m dollars to rent a car for the weekend. On the drive home, she buys $45 worth of gasoline. Her friend Melody pays for one-half the cost of the car rental only. Write an expression you could use to determine how much Sophie spent.
Answer:
1/2m + 45
Step-by-step explanation:
We are told in the question that:
On the drive home, she buys $45 worth of gasoline.
Her friend Melody pays for one-half the cost of the car rental only.
Sophie pays m dollars to rent a car for the weekend.
The amount sophie pays for car rental = m - 1/2m
= 1/2m
Therefore, the expression used to determine how much sophie spent is written as:
1/2 × $m + $45
1/2m + 45
<span>x(1^2)-2(1)+4(1^3)=6
x - 2 + 4 = 6
x + 2 = 6
x = 4 </span>
When one (not two!) of them is negative:
for example the product of -1 and 6 is -6, which is less than both factors.
It's equal to both factors when they're both 1:
1 x 1=1
Answer:
Step-by-step explanation:
rewrite each equation
1) 2x+12y=68
2)8x-12y=-28
because the y values are the same number but opposite signs they will cancel out nicely.
10x=40
x=4
now lets plug x into any of the equations.
2(4)+12y=68
12y=60
y=5
(4,5)
