Answer:
x = (total exercise time - walking time) / number of miles run
Step-by-step explanation:
Let the time it took Maggie to run a mile = x ( already given)
x = distance ran / running speed
Total time the whole exercise took = 125 minutes.Total time spent walking = 25 minutesTotal time it took her to run 9 miles can be obtained by subtracting the time she spent walking from the total exercise time.
125 - 25 = 100 minutes.
Therefore, it took Maggie 100 minutes to run 9 miles
We can set up a linear relationship as shown:
9 miles took 100 minutes
1 mile will take x minutes
x = 100 / 9 minutes.
However, the question asked us to write an equation to show this process.
We simply recap the processes in a mathematical form:
x = (total exercise time - walking time) / number of miles run

-5(x-7)<15 solve for x
Answer: X>4
Step-by-step explanation: use distributive property. -5 times X times -7. Subtract -35 from both sides. +35-35 cancels out. Subtract 35 from 15. Divide -5 from both sides. Edit: omg I just realized I didn’t change the sign!

I bought 500 pieces of candy. If 42% of the candy was eaten. How many pieces
were ate?
Answer: 210
Step-by-step explanation:
42% is equal to the fraction 42/100.
We can multiply 42/100 by 500 to find how much candy was eaten.
42/100 x 500 = 210.
Therefore, 210 pieces of candy were eaten. Hope this helps and good luck!
Answer:
210
Step-by-step explanation:
500 - 42%= 290
500 - 290 = 210

Answer:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°
Answer:
y = 62
x = 122
Step-by-step explanation:
58 + 60 = 118
118 - 180 = y
118 - 180 = 62
y = 62
x = 180 - 58 = 122

Which equation represents an ellipse?
2x2 – 4xy + 2y2 + x – 3y + 5 = 0
2x2 – 6xy + y2 + 8x – y + 2 = 0
3x2 + 7xy + 8y2 + 3x – 9y + 5 = 0
9x2 + 3x + 9y2 – 2y + 5 = 0
Answer:
C: 3x^2 + 7xy + 8y^2 + 3x – 9y + 5 = 0
The equation that represents an ellipse; 3x^2 + 7xy + 8y^2 + 3x – 9y + 5 = 0. so option C is correct.
What is the equation of ellipse if its major and minor axis and center are given?Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis,
then the equation of that ellipse would be:
[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]
Coordinates of its foci would be: (h \pm c, k) where c^2 = a^2 - b^2

You are offered a job that pays a different amount each day. The
first day, you are paid l¢. The second day you are paid 2¢. The
third day you are paid 4¢. Each day, your pay continues to
double. Write an equation that would describe the amount, in
cents, you would be paid on a particular day.
Answer:
Salary by day = .01 * 2^(n-1)
where n = # of days so
day 1 = .01 * 2^(1 -1) = .01 * 2^0 = .01
day 2 = .01 * 2^(2 -1) = .01 * 2^1 = .02
day 3 = .01 * 2^(3 -1) = .01 * 2^2 = .04
day 4 = .01 * 2^(4 -1) = .01 * 2^4 = .08

The length of side A'B' is 7 units, so the correct option is B.
What is the length of A'B'?We know that the side length is invariant under rotations, that means that the equivalent sides of the preimage and the image have equal length, then:
AB = A'B'.
We can see that AB= 7, then we can conclude that the correct option is B.
A'B' = 7 units.
