Answer:
111 apples cost $3.30 and 111 oranges cost $2 (1 apple costs nearly $0.03 and 1 orange costs nearly $0.02)
Step-by-step explanation:
Let the price of 111 apples be $x and the price of 111 oranges be $y.
1. 111 apples and 111 oranges cost $5.30, thus
x+y=5.30
2. 111 apples and 222 oranges cost $7.30, then
x+2y=7.30
Subtract the first equation from the second:
x+2y-x-y=7.30-5.30
y=2
Substitute it into the first equation:
x+2=5.30
x=3.30
111 apples cost $3.30 and 111 oranges cost $2 (1 apple costs nearly $0.03 and 1 orange costs nearly $0.02)
Answer:
B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.
Step-by-step explanation:
A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.
Answer:
8r+9p-7
Step-by-step explanation:
12p-3p=9p
8r+9p-7
6 + 2(x - 5) = -40 - 5(x - 3)
6 + 2x - 10 = -40 - 5x + 15
-4 + 2x = -25 - 5x
2x = -21 - 5x
7x = -21
x = -3
