Step-by-step explanation:
x+y=17 (First equation)
x-y=3 (Second equation)
Solving Equation (i)
x+y=17
x=17-y(First equation)
Putting value of x in equation (ii)
x-y=3
x=3+y
17-y=3+y
17=3+y+y
17=3+2y
2y=17-3
y=14/2
y=7
Putting value of y in equation(i)
x=17-y
x=17-7
x=10
Answer:6
Step-by-step explanation:
when x is -1 y is 6. input -1 as x in the equation and solve, otherwise graph.
The answer is C!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
9 cups
Step-by-step explanation:
We can write a ratio to solve
5 cups x cups
------------ = ----------------
80 cookies 144 cookies
Using cross products
5 * 144 = 80x
720 = 80x
Divide by 80
720/80 = 80x/80
9=x
