Answer:
3a × 4a = 12 a^2
Step-by-step explanation:
each and every term is multiplied, never leave any term without multiplying it
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)

Answer
Find out the what is the clearance price of a manatee.
To prove
As given
The gift shop at manatee mall was having a clearance sale.
Everything was marked down 30%.
The original price of a manatee hat was $12.
30 % is written in the decimal form.

= 0.30
30% of the original price of a manatee = 0.30 × 12
= $ 3.6
Clearance price = original price - 30% of the original price
= 12 - 3.6
= $ 8.4
Therefore the clearance price be $8.4 .
Answer:
r = 16
Step-by-step explanation:

Multiply both sides by 8

Divide both side by 3

OR
Multiply both side by (8/3)

write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?
Let x be the distance run on the fifth day
Total distance run on all the four days = 2.3 * 4 = 9.2 km
Required equation : x + 9.2 = 14
x = 14 - 9.2
x = 4.8 km
