I'm guessing that the hidden question is how many dimes does Omar have? because this is the first thing I asked myself when solving this equation.
So how many dimes does Omar have?
5 + 3 = 8
Now we know that one dime = 10 cents, so to find the amount of money in cents, all we need to do is multiply 8 * 10
8 * 10 = 80
Omar has 80 cents
Question 3 options:
a.1,500 x 12
b.1,500 + 12
c.1,500 - 12
d.1,500 / 12
Answers
Answer:
a.
Step-by-step explanation:
if they make 1,500 a month then you would multiply it by 12, because there are 12 months.
Answer:
A. $1.500 × 12
Step-by-step explanation:
Since there are 12 months in a year, we need to multiply $1,500 by 12. To make this easy, I'll show the progression from month to month.
Multiplying is simply adding the same number a given number of times, in this case, 12. Here is a visual representation of multiplication.
1st month $1,500
add $1.500, result is same as $1,500 x 2
2nd month $3,000
add $1.500, result is same as $1,500 x 3
3rd month $4,500
add $1.500, result is same as $1,500 x 4
4th month $6,000
add $1.500, result is same as $1,500 x 5
5th month $7,500
add $1.500, result is same as $1,500 x 6
6th month $9,000
add $1.500, result is same as $1,500 x 7
7th month $10,500
add $1.500, result is same as $1,500 x 8
8th month $12,000
add $1.500, result is same as $1,500 x 9
9th month $13,500
add $1.500, result is same as $1,500 x 10
10th month $15,000
add $1.500, result is same as $1,500 x 11
11th month $16,500
add $1.500, result is same as $1,500 x 12
12th month $18,000

The number of runners that'll be needed for the team will be 6 runners.
Number of miles for the relay race = 1 1/2 miles
Miles to be covered by each runner = 1/4 miles
Therefore, in order to get the number of miles that are needed for the team, we will have to divide 1 1/2 miles by 1/4 mile. This will be:
= 1 1/2 ÷ 1/4
= 3/2 ÷ 1/4
= 3/2 × 4/1
= 6
Therefore, 6 runners will be needed for the relay race.
