Answer: 3+7+9=19.....7/19=0.368 percent. Move the decimal two places to the right and round up for 37%
Step-by-step explanation:
Add all the colors together to get a TOTAL amount of ALL marbles.
The total amount for this problem is 19 (3+7+9=19)
The blue amount of marbles is given as 7.
Divide the blue amount (7) by the total amount (19) for the specific percentage for that color.
x = 5.25
since there is a scale factor of 1.75, you multiply 3 * 1.75 and get 5.25

4/9+1/5=20/45+9/45=29/45 of the wall is covered up by two couches
The sales tax can be found through multiplying the total by the decimal form of the given sales tax (7.5=0.075). This operation yields 40.5 or $40.50. I really hope this helps!:)
If log2 (x-3) =1
It means that:
2^1 = x-3
2=x-3 |+3 to both sides
2+3=x
x=5
