Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
Step-by-step explanation:
Answer:
95
Step-by-step explanation:
Use the mean formula: mean = sum of elements / number of elements
Plug in the mean and number of elements, then solve for the sum of the numbers:
mean = sum of elements / number of elements
19 = sum of elements / 5
95 = sum of elements
So, the sum of the numbers is 95.
Answer:
31 1/3
Step-by-step explanation:
3x-10=84, given
3x=94, add 10 to both sides
x = 31 1/3, divide both by three
$18.75/3 shirts= $6.25 per shirt.
The missing number is 12
because the pattern is that the the numbers below and to the right of a number equals that number. ex: 3+4=7. so in order to find the missing number you have to do the opposite of addition, which is subtraction. (17-5=12)
