72/75 is 72:75 written as a fraction, it can't be simplified.
Don't trust me but it's probably the first one. Just using context clues
Number of students N, y years
N = 700 + 50y
N = 700 + 50 x 10 = 1200 (C)
Left not painted percentage = 100 - 60 = 40 %
Left = 40/100 x 45 = 18 (H)
Answer:
Step-by-step explanation:
1) -2x + 14 > 16
-2x > 16-14
-2x > 2
x > -1
2) 3x - 7 < 20
3x < 20+7
3x < 27
x < 9
3) 5x + 2 ≥ 12
5x ≥ 12 - 2
5x ≥ 10
x ≥ 2
4) -x + 3 ≤ 5
-x ≤ 5 -3
-x ≤ 2
x ≤ -2
Answer:
y = (8/5)x - 3
Step-by-step explanation:
Slope:
(-19-5)/(-10-5)
= -24/-15 = 8/5
y = (8/5)x + c
5 = (8/5)(5) + c
c = 5 - 8 = -3
y = (8/5)x - 3
