Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
Answer:
y = -3x + 7
Step-by-step explanation:
Points on the graph: (0, 7) and (3, -2)
Slope:
m=(y2-y1)/(x2-x1)
m=(-2-7)/(3-0)
m=(-9)/3
m = -3
Slope-intercept:
y - y1 = m(x - x1)
y - 7 = -3(x - 0)
y - 7 = -3x
y = -3x + 7
One 16 oz can of veggie soup cost $ 1.78......1.78/16 = 0.11 per oz
1 pint = 16 oz......so 2 pints = (2 * 16) = 32 oz
so 32 oz ( or 2 pints) of veggie soup cost $ 3.17.....3.17/32 = 0.10 per oz
so the better deal (the cheapest one) is the 2 pints for $ 3.17
C. 5 to 3
The company has 20 pickup truck and 32-20=12 cargo trucks. The ratio between them is 20/12=5/3 simplifying by 4.
