5(2x + 3y) - 4(3x - 5y)
5(2x) + 5(3y) - 4(3x) + 4(5y)
(10x + 15y) + (-12x + 20y)
(10x - 12x) + (15y + 20y)
-2x + 35y
rewrite the fractions so the have the same denominator ( bottom number)
Multiply 2/5 by 2 to get 4/10
Now you can add 4/10 and 3/10 to make 7/10.
7/10 of the land is corn or wheat.
Answer:
m = 1 / 2
Step-by-step explanation:
The slope formula is as follows:
m = y2 - y1 / x2 - x1
Now we insert the numbers into the formula:
m = 9 - 6 / -3 - (-9)
m = 3 / 6
m = 1 / 2
Get into y=mx+b form
m=slope
b=y intercept
solve for y
12x+2y=-60
minus 12x both sides
2y=-12x-60
divide both sides by 2
y=-6x-30
slope is -6 and y intercept is -30
