Answer:

22

Step-by-step explanation:

Given x = 3, we can substitute this value into the given expression to evaluate it.

x = 3

6x + 10 - 2x    (Substitute)

= 6(3) + 10 - 2(3)    (Simplify)

= 18 + 10 -6    (Simplify)

= 22

Peter made a square pin for his pet guinea pig to roam in. One side was 18.2 cm. What is the area of the pin?
Zina [86]

Hi!

Answer:

A) 331.24

Step-by-step explanation:

To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

I hope this helps! :)

Artist 52 [7]

Answer:

$478.80

Step-by-step explanation:

We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.

First of all, we will find cost of each meal with tax as:

\text{Cost of each meal with tax}=\$12+\$12\times \frac{5}{100}

\text{Cost of each meal with tax}=\$12+\$12\times 0.05

\text{Cost of each meal with tax}=\$12+\$0.6

\text{Cost of each meal with tax}=\$12.6

Now, we will find total persons at the sport banquet as:

\text{Total persons at banquet}=15+2+21

\text{Total persons at banquet}=38

To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.

\text{Total cost of food for the banquet}=\$12.6\times 38

\text{Total cost of food for the banquet}=\$478.8

Therefore, the total cost of food for the banquet is $478.80.
