Answer:
y=5
Step-by-step explanation:
The ratio of the sides are similar
red/ yellow
2/6 = y/ 15
Using cross products
2*15 = 6*y
30 = 6y
Divide each side by 6
30/6 = 6y/6
5 =y
Answer:
B. x=7
Step-by-step explanation:
(2x+5) = (x+12)
2x = x+7
x=7
Answer: x = 16
Step-by-step explanation:
24 + 2 + 4x = 90
26 + 4x = 90
4x = 64
x = 16
Price of 12 pounds of trail mix = 12 x $4.20
= $50.40
Let the number of pounds of skittles and trail mix be x,
number of pounds of skittles = 12 - x
price of pounds of skittles = $16.70(12 - x)
= $200.40 - 16.7x
total amount = 10.93x
200.40 - 16.7x + 50.40 = 10.93x
250.80 = 27.63x
x = 10 (nearest whole number)
the minimum number of pounds of skittles is 10.
