Answer = 10=21
When you’re multiplying numbers with exponents with the same base (10 is the base) all you have to do is add the exponents
18 and 3 are the exponents we’re dealing with, so we add them and get 21. The base stays the same
10^18 x 10^3 = 10^21
Answer = 10=21
Answer:
There will be No solution for the equation 
. Option B is correct.
Step-by-step explanation:
We need to determine how many solutions the equation have.
Solving the equation and finding the solutions
Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.
Simplifying
Solving the equation we get 0=9 which is false. So, there will be No solution for the equation . Option B is correct.
Answer:
A
Step-by-step explanation:
A: 3 times a week, 45 minutes, 15 minutes, 4 weeks
In the beginning of the word problem it says Brian goes to the gym 3 times a week. We need to know that because you have to use that number later for multiplication.
The 45 minutes are important because he spends 45 minutes at the gym each visit.
The 15 minutes are important because you have to subtract that from 45 because 15 of the 45 minutes are spent on weights, the rest of the time is spent on the treadmill, and we need to know how long Brian is on the treadmill in 4 weeks.
So the equation should be: [(45-15)* 3]*4
Solution step-by-step:
45-15= 30 minutes for treadmill
30*3=90 minutes per week
90*4= 360 minutes in 4 weeks
Convert into hours:
360 minutes/60 minutes= 6 hours
Hope this helps!!! :D
Unit rate is 3.7 if that’s what you are asking for, you were not very specific.
