Michelle's car needs repairs. The mechanic said it will be $144 for parts plus $80 an hour to repair the car. How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
Answer:
3 hours
Step-by-step explanation:
Total cost = 144 + 80h
Where h = number of hours
How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
384 = 144 + 80h
Subtract 144 from both sides
384 - 144 = 144 + 80h - 144
384 - 144 = 80h
240 = 80h
Divide both sides by 80
h = 240 / 80
= 3
h = 3 hours

August is making dinner for 8 people. She opens 7 cans of soup. Each can is 16 ounces. If everyone gets the same amount of soup, how much soup will each person get?
This is for my sister, and her teacher said that the correct answer is 3.5 ounces. If anyone gets this answer, please show how you got the answer...thank you!
Answer:
14oz soup/ person
Step-by-step explanation:
the answer would be 14oz of soup/person
multiply 7 (cans of soup) by 16 (oz per can)
7*16=112
divide 112 (oz of soup total) by 8 (number of people feeding)
112/8=14

The solution to the given system of equations will be (0, -1). which is the correct option (B).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.
y = 2x - 1 ....(i)
y = -4x - 1 ....(ii)
Substitute the value of equation (i) in equation (ii) and solve for variable x :
2x - 1 = -4x - 1
Rearrange the terms of variable "x" and combine them,
2x + 4x = -1 + 1
6x = 0
x = 0
Substitute the value of x = 0 in equation (ii) and solve for variable y :
y = -4(0) - 1
y = -1
Therefore, the solution to the given system of equations will be (0, -1).

Find the exact length of the third side.
Answer:
[tex]24x^{2} +7x^{2} =[/tex]
step-by-step explanation:
You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
Answer:
this is a right angle triangle.
which means that we can use hypotenuse theorem to solve it.
the hypotenuse theorem:-
a^2 +b^2 =c^2
where a and b are the sides opposite to the hypotenuse.
[(the longest side) the longest side of the triangle is always opposite to the right angle]
so...
a = 24
b = 7
a^2 + b^2 = c^2
24^2 + 7^2 = c^2
576 + 49 = c^2
625 = c^2
don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.
√625 = c
25 = c
thus the length of the third side is 25.
