Answer: If 1 pair of socks = 4 and 1 shirt = 10 then your answer will be C, 14.
Explanation: in the beginning it says ONE PAIR OF SOCK AND 2 SAME SHIRT =24. One sock=4 and 2 shirts=20 , 20 + 4 = 24. Solved.
Then 3 pairs of socks (4 x 3 = 12) and 2 of the same shirts (10 + 10 = 20) then 20 + 12 = 32!!

Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4
Answer:
-3
Step-by-step explanation:
3y×(2y+5)
Multiply each term in the parentheses by 3y
3y×2y+3y×5
Calculate the product
6y²+3y×5
Now we do the same thing only different way
3y×2y
Multiply the numbers
6y×y
If a term doesn't have an exponent , it is considered that the exponent is 1
6y^1×y^1
Multiply the terms with the same base by adding their exponents
6y^1+1
add the numbers
6y²
6y^2+3y×5×
calculate the product
6y²+15y
It's the same thing only different way ok
3y×5
Multiply the numbers
15y
answer: 6y²+15y

Answer:
Step-by-step explanation:
To solve this problem, we must add up all the side values.
Our equation for the perimeter will look like:
Now lets plug in our values for our sides and solve:
Now lets combine like terms:
So this is our perimeter!
Hope this helps! :3
