2.)112
3.)99
I think these are right
Step-by-step explanation:
Answer:
y= -4x+18
Step-by-step explanation:
the answer is x=y/4+9/2 when solving for x
mark me as a brainliest please <3 thank you!
The answer is y = 640 - 75x
As her balance starts at a fixed point ( 640)
and decrease every x weeks by 75
Hope it helps

Answer:
90
Step-by-step explanation:
This is an increasing sequence, with -9 as its first term. The first increase is +3, then +5, +7, and +9. The differences increase by 2 each time. The sixth term will be 15 + 11, and the seventh would be 15 + 11 + 13. We can follow this pattern to get to the tenth term. 15 + 11 + 13 + 15 + 17 + 19 = 90
Answer:
x=120, y=70
Step-by-step explanation:
X must be 120 degrees as it is on a parallel line.
The outer+interior angles of a triangle on a straight line must be supplementary, so the second angle of the triangle is 180-120=60.
All interior angles of a triangle add up to 180 degrees: 50+60+y=180
y+110=180
y=70
