Answer:
3/4 / 5/16
Step-by-step explanation:
3/4 / 5/16 = 15/2 pound bags
Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
Answer:
$3.70
Step-by-step explanation:
$25.30 = 2P + 4D. p for popcorn and d for drinks
P= $5.25
$25.30 = 2($5.25) + 4D
$25.30 = $10.50 + 4D
-10.50. -10.50
inverse operations
$14.80 = 4D
÷4. ÷4
Inverse operations
$3.70 = D
