By trial and error, I got it first correctly. The granola
bars cost $1 each and the yogurt is $.50 per cup. By plugging this in to each
equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt
equals $3.50, for a total of $15.50. The second account would produce $6 +
$5.50, which equals $11.50.
Answer:
29
Step-by-step explanation:
You need to find the average number of students
Add up all the students
27+31+28+33+26
145
Divide by the number of classes
145/5
29
The average is 29
She subtracted 6 from a certain number and then divided the result by 3, giving her 35.
(x - 6) / 3 = 35
x - 6 = 35*3
x - 6 = 105
x = 105 + 6
x = 111
so she should have subtracted 3, then divided by 6
(111 - 3) / 6 = 108/6 = 18 <===
Answer:
68
Step-by-step explanation:
k=-34
absolute value makes k positive
34+34
There are no real solutions.
if you subtract 20 from both sides, you get
x² = -16
You cannot find the square root of a negative number without using i, so there are no real number solutions.
