Answer:
61 bikes are not mountain bikes.
Step-by-step explanation:
To figure this out you have to simply subtract the amount of mountain bikes from the total amount of bikes.
98 - 37 = 61
Now you know that 61 of the bikes are not mountain bikes.

4x + 8 = 2x + 6
-2x ----- -2x
2x + 8 = 6
----- -8 ---8
2x = -2
÷-2 ÷-2
x = -1
Hope this helps!
1. B forms a proportion, this is what I did, i simply 10/18 to 5/9 and i try to see if 5/9 is equivalent to 25/45 and it is. 5/9*5/5= 25/45
2. You multiply 27*4=108 then 108/12=9 so a=12
3. you multiply 16*21=336 then 336/12=28 so b=28
Hope this helps!
First you need to set up the frequency chart. The columns can be Multiples of 3 and not multiples of 3. The rows can be Multiples of 4 and not multiples of 4 like shown in step 1. in attached file
Then we start adding in values I will add 20 as the total numbers as in step 2 in attached file.
Next I place in the Multiple of 9 that is not 3, and the total multiples of 3, and total multiples of 4 in step 3.
Based on the totals I can assume that there are 10 that are not multiples of 4 and ten that are not multiples of 3 shown in step 4
In step 5 I fill in the insides so that the totals will add up so we know that for multiples of 3 9+1=10 so I fill in the one at the top left corner.
In step 6 the only numbers left to fill in the totals would be 9 and 1 for values that are not multiples of 3 and not multiples of both.
This means it’s 6(3)^2. The PEMDAS process will help in this situation. Since exponents (E) come before multiplication (M), you would raise 3 to the 2nd power first. 3^2 is the same as 3 times 3, which equals 9. Now, you can multiple 6 by 9, which would result with 54. 54 is your answer!
