The equation m=40g gives the distance in miles, m, that a car can travel using g gallons of gas
a. If the car has gone 140 miles, how much gas was used
B. Write an equation the represents the inverse function
Answer:
3.5 gallons
Step-by-step explanation:
140=40g
140/40=g
a) The car used 3.5 gallons of gas
b) The inverse function is g=m/40
What is an inverse function?In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f(x) produces the output. A function that has an inverse is called invertible and the inverse is denoted by f⁻¹
Given here, distance = 140 and equation m=40g then using the equation we get
140 = 40 ×g
g= 3.5 gallons
and the inverse function is given by g = m/40
Hence the car uses 3.5 gallons and we found the inverse function is g=40/m

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?
Answer:
$2 more.
Step-by-step explanation:
In this question, we have to find how much more money Victoria is saving.
We know that Jacob saved $174 in 3 months.
We also know that Victoria saved $360 in 6 months.
Lets find how much money they save per month:
Jacob:
174 ÷ 3 = 58
Victoria:
360 ÷ 6 = 60
Jacob is saving $58 per month and Victoria is saving $60 per month.
This means that Victoria is saving $2 more than Jacob per month.

The spring concert at a certain high school sold 149 tickets. Students were charged $2 each and adults $6 each. The income from the sale of tickets was $626. How many students and how many adults bought tickets?
The final statement is: 67 student tickets and 82 adult tickets were sold.
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: Total tickets =149 student ticket=$2 and adult ticket=$6
Tickets sold worth=$626
Let x tickets be bought by students and therefore 149-x be brought by adults then we have
2x+6(149-x)=626
-4x+894 = 626
x=268/4
x=67
∴ x=67 & 149-67=82
Hence, 67 student tickets and 82 adult tickets were sold.

The number of pounds that can be safely loaded onto an elevator, X, can be represented by
the inequality x < 1,200. Which number line correctly represents this inequality?
Answer:
the third one
Step-by-step explanation:
The inequality says X is less than 1200, this means the arrow needs to be pointing to the left. Because X cannot equal 1200, the circle on 1200 should not be filled in. It is only filled in if it is included.

Answer:
43
neeed...20...charetors
The integer that represents the altitude closer to sea level is 10.
What is addition?Addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value. A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.
We are informed that Markers were placed at altitudes of 10 and 15 feet below sea level
Then we need to find the integer that represents the altitude closer to sea level.
We can say that 10 is negative (below the sea level), and 10 is 10 spaces away from zero on the number line, meaning the answer could be |10|.
The sea level would be 0 and the 10 would be -10 and the 15 will be -15
Hence, the 10 is closer to the sea level.
Thus the integer that represents the altitude closer to sea level is 10,

Given
The attached triangle
Required
Determine the value of x
x represents the height of the triangle.
And the area of a triangle is calculated as:
[tex]Area = \frac{1}{2} * Base * Height[/tex]
Where
[tex]Base = 4[/tex]
[tex]Area = 16[/tex]
[tex]Height = x[/tex]
The expression becomes
[tex]16 = \frac{1}{2} * 4* x[/tex]
[tex]16 = 2* x[/tex]
[tex]16 = 2x[/tex]
Divide through by 2
[tex]8 = x[/tex]
