Answer:
x = -2
y = 7
Step-by-step explanation:
x = 12 - 2y
7(12 - 2y) + 4y = 14
84 - 14y + 4y = 14
84 - 10y = 14
10y = 70
y = 7
x = 12 - 2 x 7
x = 12 - 14
x = -2
Answer:
If a price doubles, then it increases by 100%
Step-by-step explanation:
To find the percent increase, use the percent increase formula below.
(New - Old)/Old * 100 = percent increase
You can choose any number to be the old number and you'll get the same answer. For this purpose, we'll use 65. This would make the new value 130.
(130 - 65)/65 * 100 = Percent Increase
65/65 * 100 = Percent Increase
100% = Percent Increase
Answer:
We would use to describe numbers from 1 - 6.
Step-by-step explanation:
We represent the flavors as a set in Roster form.
F = {grape, strawberry, lemon, orange, apple, watermelon}
Note that that there are 6 flavors.
i.e., n(F) = 6
Since we have to assign a number for each flavor, and there are 6 flavors, we would use to describe numbers from 1 - 6.
