Answer:
92/69 cannot be simplified
Step-by-step explanation:
It's a simultaneous equation:
Steps:
1.Number the equations..
a+b=77 -1
a-b=13 -2
2. Choose what variable you want to use. In this case I would use the "b". Since the signs in front of the "b's" are different, add the two equations together
a + b = 77
+ + +
a (-b) = 13
Which gives;
2a = 90
Then solve to find a:
2a=90
a= 90/2
a=45
3.Then plug the "a" value into any of the original equations to find the "b" value. I would use equation 1 since the all the variables are positive.
a + b = 77
(45) + b = 77
b=77-45
b=32
4.Solution
a=45
b=32
x-axis is y=0, so the answer is D.

Answer:
p = -2
Step-by-step explanation:
p − 10p + -5p + 14p − -9p − 2 = -20
-9p + 9p + 9p = -20 + 2
9p = -18
p = -2
Answer:3 3/8
Step-by-step explanation:
Im not sure but im not dumb good luck
just minus 4 from 7 = 3 and 1-4=3
