Answer:
3 times the number of yards
Let f represents the number of feet
f = 3 * y
Step-by-step explanation:
Number of feet 3 6 9 12
number of yards 1 2 3 4
1*3 = 3
2*3 - 6
3*3 =9
4*3 = 12
number of feet is 3 times the number of yards
Let f represents the number of feet
and y represents the number of yards
number of feet is 3 times the number of yards
f = 3 * y
Answer:
2nd option
Step-by-step explanation:
trinomial is 2x² + 10x -4 = 0
a = 2
b = 10
c = -4
(-b±√b²-4ac) / 2a
= [-10±√100-4(2)(-4)] / 2
= (-10±2
) / 4
= (-5+)/2, = (-5-)/2 (simplified)
Answer:
27

There ages when multiplied by 2, have to equal 54. Simply put, just divide 54 by 2 to get your answer. Thus, the answer is 27
Hope this helps.
The first thing we need to know are the prices:
popcorn 4 $
large pretzel $ 3
small soda 2 $
water $ 2
ticket costs $ x
The second thing we need to know is how many things were bought:
they bought:
four large pretzels
four bottles of water
four tickets
the mathematical expression is
Total cost: 4x + 4 (3) +4 (2)
simplifying
Total cost: 4x + 20
answer
The total cost of tickets and snacks or beverages was:
Total cost: 4x + 20
