Answer:
A. 3.15c + 0.82f
Step-by-step explanation:
c pounds of cashews for $3.15 = 3.15c
f pounds of flour for $0.82 = 0.82f
then, the expression can be used to determine the total cost is:
A. 3.15c + 0.82f
The percentage of vehicles passing through this construction zone that are traveling at a speed of 50 and 57 miles per hour
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the measures of the 3 sides.
Sum the sides and equate to 75, that is
2x - 9 + 3x + 4 + 2x + 3 = 75, that is
7x - 2 = 75 ( add 2 to both sides )
7x = 77 ( divide both sides by 7 )
x = 11
Thus
AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m
BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m
AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m
First, add t to each side:
2t - 6 = 8
Add 6 to each side:
2t = 14
Divide both sides by 2:
t = 7
Hope this helps!! :)
72 divides by 9 is 8 so 2 times 8 is sixteen so that would be the answer
