x = 11
Step-by-step explanation:
Take the fifth root on both sides.
27(x-2) = 3^5
27x-54 = 3^5
27x = 243 + 54
27x = 297
x = 297/27
x = 11
Answer:
Question 3: There are 12 boys in the class.
Question 4: 120 cookies were not oatmeal raisin.
Question 5: Target offers the best deal.
Step-by-step explanation:
If the ratio of girls to boys is 3:2, and there are 18 girls, that means there will be
* 2 = 6 * 2 = 12 boys.
Because there are 200 cookies total, and
of them are oatmeal raisin, that means that
of the cookies aren't oatmeal raisin. 200 *
= 40 * 3 = 120 cookies that aren't oatmeal raisin.
The cookies at Kroger have a unit rate of $0.45 per cookie, the cookies at Meijer have a unit rate of $0.50 per cookie, the cookies at Walmart have a unit rate of $0.38 per cookie, and the cookies at Target have a unit rate of $0.20 per cookie. So Target has the better buy.
Y = -55 because
135 + 100 = 235
180-235 = -55
