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
Answer:
Step-by-step explanation:
Do FOIL, first outside inside last
3x × 3x = 9x^2
3x × -7 = -21x
7 × 3x = 21x
7 × -7 = -49
So it would just be 9x^2 - 49
Answer:
Is wut prime or composite
Step-by-step explanation:
The integers that make the linear equation false are:
3, 78, and 126
We found that by evaluating the equation in all the options.
<h3>Which integers make the equation false?</h3>
Here we have the linear equation:
8m - 15 = 5m + 63
And the possible solutions are:
S: {3, 26, 78, 126}
To see which of these integers make the equation false, we can replace the value of m by the given values and see when the equation is false (the number in the left is different to the one in the right).
if m = 3
8*3 - 15 = 5*3 + 63
9 = 78 this is false.
if m = 26
8*26 - 15 = 5*26 + 63
193 = 193 this is true.
if m = 78
8*78 - 15 = 5*78 + 63
609 = 453 this is false.
if m= 126
8*126 - 15 = 5*126 + 63
993 = 693 this is false.
So the integers that make the equation false are:
3, 78, and 126.
