Answer:
p=4 and q could be any real number (except 1 because then CD would not be a line since the points would lie on top of each other).
Step-by-step explanation:
For CD to be horizontal, both of the y coordinates for CD need to be equal. Since we are already given one of the y coordinates (the y coordinate for D is 4), then we know that the y coordinate for C (p) is 4 as well). Since it doesn't really matter what q is (any value of q except 1 would create a horizontal line with point C as long as p=4), it is any real number except 1.

a - 8 = 10 -2a
a +2a = 10+8
3a = 18
a= 18/3
a= 6
#6
p - 11 -2p = 13 - 5p
Combine like terms
(p - 2p) +(-11) = 13 - 5p
-p - 11 = 13 - 5p
-p + 5p = 13 + 11
5p = 24
p= 24/5
p= 6

12x + 3 - 4x - 3 = 8
Combine like terms
(12x -4x) + (3 - 3) = 8
8x = 8
x= 8/8
x= 1
#8
5x -2 + 3x - 4 = 2x - 8 + 2
Combine like terms
(5x + 3x ) + (-2 - 4) = 2x + (-8 +2)
8x -6 = 2x - 6
8x - 2x = -6 + 6
6x = 0
x= 0/6
x= 0
#17
(5-x)/ 5 = 1
( 5-x)/5 * (5) = 1*5
5 - x = 5
-x = 5 -5
-x = 0
Divide both sides by 1so we can eliminate the negative sign
-x/1 = 0/1
x= 0
I hope i help :)
Answer:
120 = 3y + t
Step-by-step explanation:
120 = 3y + t because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.
