There are
.. floor(200/6) = 33 multiples of 6
in the range 1 .. 200.
There are
.. floor(200/15) = 13 multiples of 15
in the range 1 .. 200, half of which are also multiples of 6.
So, there are 33 +13 -6 = 40 numbers in the range 1 .. 200 that are multiples of either 6 or 15 or both.
The remaining 200 -40 = 160 numbers are not multiples of either.
Answer:
m = 0
Step-by-step explanation:
1/2(-1.4m+0.4)=m+0.2
We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator
-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0
Wy multiply elements
-2m^2(--(0.2)*2(-1.4m+0.4)+1=0
We use the square of the difference formula
-2m^2(+(0.2)*2(-1.4m+0.4)+1=0
So you would start by finding out how many miles per gallon you could go by dividing 494.2 by 35.3 and you would get 14 miles per gallon. Then you would multiply 14 by 18.1 and you would get 253.4 miles on 18.1 gallons.
