Do the same process for each of the 3
you have miles per how many minutes and you need miles per hour
you know 60 minutes make 1 hour convert the minutes to hours
this will gives you miles per equivalent hour
you need miles per 1 hour
Here is number 1
1) 5 miles in 20 minutes
5 miles in (20/60) hr = 5 miles in 1/3 hr
to get 1 hr multiply by 3
equation so keep the balance
5 * 3 = 15
rate = 15 miles per hour.
same process for the others
Answer:
Step-by-step explanation:
93 + (68 + 7)= 168
Answer:
x=1.5
Step-by-step explanation:
We are trying to get x by itself to see what it equals.
6(2x+3)=36
So first you want to distribute you proprieties. You do that by multiplying 6 and 2x. Then multiplying 6 and 3.
12x+18=36
Now in equations where you need to find the variable, whatever you do on one side of the equal sign, you have to do on the other side. So now we want to subtract 18 from both sides.
12x+18=36
-18 -18
Then we divide 12 from both sides.
12x=18
÷12 ÷12
Now you have your answer!
x=1.5
3.69/3=
1.23
Hope this helps! :)
Hey there! :)
Answer:
x = 5/2 and 3.
Step-by-step explanation:
Factor the equation. Find numbers that will sum up to -11 involving the coefficient of 2, and that multiply into 15.
2x² - 11x + 15 = 0
(2x - 5)(x - 3) = 0
Use the Zero Product Property to solve for the roots of this equation:
2x - 5 = 0
2x = 5
x = 5/2
----------
x - 3 = 0
x = 3.
Therefore, the two values of x that are roots of this equation are:
x = 5/2 and 3.
