Answer:
A
Step-by-step explanation:
An equation is formed of two equal expressions. The correct option is C.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The ordered pair that is a solution to the system of linear equations can be found as shown below,
6x + 5y = -7
Solving for y,
y = (-7-6x)/5
In the second equation substitute the value of y,
2x - 4y = -8
2x - 4[(-7-6x)/5] = -8
2x + (28/5) + (24x/5) = -8
10x + 28 + 24x = -40
34x = -68
x = -2
Since the only option in which the value of x is -2 is option C. It is the correct option.
Hence, the correct option is C.

Answer:
a pack of three 8-ounce containers his is a better purchase
Step-by-step explanation:
In this case, what we must do is calculate the price per ounce and the one with the best value is the best purchase:
option 1: a pack of four 6.5-ounce containers of ice cream for $ 3.77
3.77 / (4 * 6.5) = 0.145
option 2: a pack of three 8-ounce containers for $ 3.87
3.87 / (3 * 8) = 0.161
The value of the price per ounce is less in option 1, therefore, this is a better purchase
Answer:
About 444 white cars
Step-by-step explanation:
First add the number of cars, 13+34+25+10+8, you will get 90
Out of 90 cars, 10 are white so 10/90 are white
Then, set up a proportion, 10/90 = x/4,000
Do cross multiplication and your answer should be <u>about</u> 444 white cars.
