Answer:
$7; Cost of a box of apples (x)
$13; Cost of a box of oranges (y)
Step-by-step explanation:
Matt: 3x + 14y = 203 3(-y + 20) + 14y = 203 3x + 14(13) = 203
Ming: 11x + 11y = 220 -3y + 60 + 14y = 203 3x + 182 = 203
11x = -11 11y = 143 3x = 21
x = -y + 20 y = 13 x = 7
Answer:
38.63Step-by-step explanation:
Area x height
8/-3 ÷ -4/9
8/-3 * 9/-4
72/12 = 6
Answer:
y + 8 = 6(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 6 and (a, b) = (- 1, - 8), hence
y - (- 8) = 6(x - (- 1)), that is
y + 8 = 6(x + 1)
8:2 can be simplified to 4:1. (:
