Answer:
Step-by-step explanation:
Rewrite 2x-5y< 15 as follows: Add 5y to both sides. Then 2x < 15 + 5y.
Next, subtract 15 from both sides: 2x - 15 < 5y.
Finally, divide all terms by 5: (2/5)x - 3 < y
Now find the y-intercept of this line. Let x = 0. Then y = -3. Plot (0, -3) on graph paper. Now, starting at (0, -3), move your pencil point 5 spaces to the right and 2 spaces up. Plot this new point, (5, -1). Now draw a dashed line through both (0, -3) and (5, -1). Shade the area ABOVE this dashed line.

Pru, Piper, Phoebe......ratio 5:3:4...added = 12
what this means is Pru has 5/12 of the total amount, Piper has 3/12 of the total amount, and Phoebe has 4/12 of the total amount
pru = piper + 24
5/12x = 3/12x + 24
5/12x - 3/12x = 24
2/12x = 24
x = 24 / (1/6)
x = 24 * 6
x = 144 spices in total
pru has : 5/12(144) = 720/12 = 60 spices
piper has : 3/12(144) = 432/12 = 36 spices
phoebe has : 4/12(144) = 576/12 = 48 spices <====
Answer:
in 8 years each school will have about 1,040 students
Step-by-step explanation:
let 'x' = years
y = 30x + 800
y = -25x + 1240
30x + 800 = -25x + 1240
55x = 440
x = 8
