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:
3.30 for apple and 2.00 for an orange
Step-by-step explanation:
Answer: y = -2x + 6
Slope-intercept form: y = mx + b, where m = slope and b = y-int
m = -2
(-1, 8) --> -1 = x₁, 8 = y₁
Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:
y - 8 = -2[x -(-1)]
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6
