Jillian and Nikki each filled their cars with gasoline. The graphs below show the amount of gas in each car and the miles driven since filling the tank. A graph titled Jillian's Car has miles driven on the x-axis, and gallons of gas left on the y-axis. A line goes through (0, 22) and (100, 16). A graph titled Nikki's Car has miles driven on the x-axis and gallons of gas left on the y-axis. A line goes through points (0, 20) and (100, 16). Which statement is supported by the graphs? Jillian’s car holds more gasoline and gets better gas mileage. Nikki’s car holds more gasoline and gets better gas mileage. Jillian’s car holds more gasoline, but Nikki’s car gets better gas mileage. Nikki’s car holds more gasoline, but Jillian’s car gets better gas mileage.
Answers
The statement that is best supported by the graph is; Jillian's car holds more gasoline, but Nikki's car gets better gas mileage.
How to Interpret Linear Graphs?The total amount of gasoline each car tank can hold is shown on the left of each graph on the y-axis.
Jillian's car holds 22 gallons.
Nikki's car holds 20 gallons.
Jillian's car holds more gasoline.
Now we need to see which car gets better gas mileage. Getting better gas mileage means you can go farther with each gallon of gas.
With Jillian's car, after using 22 gallons of gas, you have gone 350 miles, and the gas tank is empty.
350 miles with 22 gallons is 350/22 = 15.9 miles per gallon.
With Nikki's car, you start with only 20 gallons. By the time you drive 350 miles, you still have some gas left. Not only did you start with less gas, 20 gal vs. 22 gal, but after driving the same distance, 350 miles, there is still some gas left in the tank, 6 gallons.
That means Nikki's car used 20 - 6 = 14 gallons to drive 350 miles. 350/14 = 25 miles per gallon.
The more miles per gallon you get, the better the mileage. Thus;
25 miles per gallon is better mileage than 15.9 miles per gallon.
Nikki's car has a smaller gas tank, but it gets better mileage.

The value of the area are;
Rectangle A = 54 square units
Triangle B = 2 square units

Whole figure = 62 square units
How to determine the area of the composite figureThe formula for determining the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleFrom the figure shown, we have two rectangles
Area of the bigger rectangle;
Length = 9
Width = 6
Now, substitute the value
Area = 9(6)
Multiply through
Area = 54 square units
Area of the smaller rectangle
Length = 9 - 7 = 2
Width = 9 - 6 = 3
Substitute the values
Area = 2(3)
Multiply through
Area = 6square units
The formula for area of a triangle is expressed as;
Area = 1/2 base× height
Base = 9 - 6 = 3
Height = 9 - 2 = 3
Substitute the value
Area = 1/ 2 ×2(3)
Area = 6/ 3
Area = 2
The total area = Rectangle A + rectangle B + Triangle

What is the value of z in the system shown below?
x+y+z=6
x + 2y = 5
2x+z = 5
Answers
========================================================
Explanation:
I'll use the substitution method to solve this system of equations.
Solve the third equation for z
2x+z = 5
z = 5-2x
Then solve the second equation for y
x+2y = 5
2y = 5-x
y = (5-x)/2
y = -0.5x+2.5
Plug each of these into the first equation so we can solve for x.
x+y+z = 6
x+(-0.5x+2.5)+(5-2x) = 6
-1.5x+7.5 = 6
-1.5x = 6-7.5
-1.5x = -1.5
x = (-1.5)/(-1.5)
x = 1
Let's use this to find y and z
y = -0.5x+2.5 = -0.5*1+2.5 = 2
z = 5-2x = 5-2*1 = 3
Therefore,
x = 1
y = 2
z = 3
Or we can write it like this: (x,y,z) = (1,2,3)
-------------------
Check:
Plug these values into equation 1 and simplify
x+y+z = 6
1+2+3 = 6
6 = 6
We get the same thing on both sides.
This confirms equation 1.
Repeat for equation 2.
x+2y = 5
1+2*2 = 5
1+4 = 5
5 = 5
This confirms equation 2.
Lastly, plug those values into equation 3
2x+z = 5
2*1+3 = 5
2+3 = 5
5 = 5
Equation 3 is confirmed.
All three equations are true when (x,y,z) = (1,2,3). The solution is fully confirmed.

Answers
Answer:

Step-by-step explanation:
Hakeem is starting a running plan to train for a race. In the first week of his running plan, Hakeem will run 11 miles. The plan calls for Hakeem to increase his weekly milage by 2 miles every week. If Hakeem sticks to the plan, how many miles would he be expected to run during his 8th week of the training plan?
This can be described as:
11 + 2w
when w = week
because he runs 11 miles the first week, he only has 7 weeks of 2 mile increases:

Supergym is a national chain of gyms. This year, its employees sold 10,412 gym memberships, which turns out to be 52% more than they sold last year. How many memberships did they sell last year?
Answers
The supergym sold 15,826.24 membership last year
How to calculate the number of membership sold ?
This year it's employees sold 10,412
This number is 52% more that they sold last year
The first step is to calculate 52% of 10,412
52/100 × 10,412
= 0.52 × 10412
= 5,414.24
The number of membership sold this year can be calculated as follows
= 5414.24 + 10,412
= 15,826.24
Hence the number of membership they sold last year is 15,826.24

The probability of rolling exactly one six = 0.04
what is probability ?
Probability is a branch of mathematics that deals with the occurrence from of a random event . the value is expressed from zero to one .Probability has been introduced in mathematics to predict how likely events are to happen .
So , acc the question "exactly one six " means that one roll so that probability must be doubled the probability of " not six " is 4/5 . the probability of a 6 on the roll and not on the second is 1/5 x 4/5 =4/ 25 .
The six could come on the second roll so thst probability must be doubled .
the overall probability of exactly one six 8/25 or 0.32
completing toatl probability -no sixes =4/25 x 4/25 =16/25 =0.04
two sixes =1/5x 1/5 =1/25= 0.04

Write the equation of the line that goes through the point (3,-3) and has a slope of -5/3 (in slope intercept form).
Answers
The equation of the line that goes through the point (3,-3) and has a slope of -5/3 is y=(-5x+6)/3.
What is a slope?In mathematics, line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent a slope; reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."
The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio can also be written as quotient ("rise over run"), which produces same number for every two distinct points on the same line. A declining line has negative "rise." The line might be useful, as determined by road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.
The slope's absolute value serves as a gauge for line's steepness, incline, or grade. A steeper line is indicated by slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical.
if we let y = mx + b, where m is the slope and b is the intercept, and y - y1 = m (x - x1), then:
3(y + 3) = - 5 (X - (-3))
3y + 9 = - 5 X + 15
3y = -5 X + 6
y=(-5x+6)/3
Check:
When x = 3, y should equal - 3, so:
Y = (- 5 (3) + 6)/3 = -3
