Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)

A circle is made up of 360 degrees. Lets find the decimal form of each part of the circle.
White: 122.4/360 = 0.34
Red: 115.2/360 = 0.32
Silver: 68.4/360 = 0.19
Blue: 54/360 = 0.15
Now, solve for the car color that is not red or blue.
1 - (0.15 + 0.32)
1 - (0.47)
0.53
Therefore, the answer is C.
Best of Luck!
If Suzanne can read 1 page in 3 minutes, that means that in ONE hour, she can read 20 pages.
1 page per 3 minute
60minutes : 3 = 20 pages
Now, multiply 20 pages by 5 hours.
20 x 5 = 100.
I hope it helps! (She's pretty slow at reading)
The answer multiplied if it doubled the its times 2 tripled it’s timeS 3 quadruple then times 4
