Answer:
2x+3y=170.......1
1x+5y=225.......2
multiplying equation 2 by 2 and subtracting eq.1 &2
2x+3y-2x-10x=170-225
-7x=-55
x=55/7
55/7+5y=225
5y=225-55/7
y=1520/(7×5)=304/7
Answer:
C. Slope is 2
Step-by-step explanation:
Since this equation is written in the y=mx+b equation, 2 would be the slope, because any number that comes before x (AKA "m") is always the slope. For example, if you were trying to find the slope for the equation y=4x+19, 4 would be the slope.
The answer to your question is 11/12
Answer:
a) x=7
b) x=4
c) x= 1/9
I hope this helps! Do you need more help?
It went from 10 to -2, so you need to find the difference. The way you'd do this is: 10 - (-2). Do you know how to subtract a negative number from a positive number?
