Answer:
p> -4
Step-by-step explanation:
3p + 2 > -10
3p > -10 -2
p> -4
Writing this problem in symbols instead of in words greatly simplifies it:
(2 2/3) * (1 1/5) * (1 1/2)
Write each quantity (inside each set of parentheses) as an improper fraction:
(8/3) * (6/5) * (3/2)
Now multiply the numerators thru: 8*6*3 / 3*5*2
Notice that we can reduce this by dividing the 8 by the 2 and dividing the 6 by the 3: 4*3*3 36
---------- = -----------

Answer:
y = 2x² - 5x + 7
Step-by-step explanation:
General form of a quadratic is:
y = Ax² + Bx + C
Using the given points, construct equations and solve for A,B and C.
When x = 0, y = 7
7 = A(0)² + B(0) + C
C = 7
y = Ax² + Bx + 7
When x = -1, y = 14
14 = A(-1)² + B(-1) + 7
A - B = 7
A = 7 + B
When x = 1, y = 4
4 = A(1)² + B(1) + 7
A + B = -3
(7 + B) + B = -3
2B = -10
B = -5
A = 7 + (-5)
A = 2
y = 2x² - 5x + 7
Answer:
125
Step-by-step explanation:
if the school gets $20 per wrapping paper sold
then in order to earn 2500 the school must sell 2500/20=125
S + c = 79.10
s = 3.50 + 3c
3.50 + 3c + c = 79.10
3c + c = 79.10 - 3.50
4c = 75.60
c = 75.60/4
c = 18.90 <==== amount spent on coffee
s = 3.50 + 3(18.90)
s = 3.50 + 56.70
s = 60.20 <=== amount spent on soy lattes
