Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42

Answer:
20%
Explanation:
What we know:
- there are 25 cans in total
- 5 of them are root beer cans
Using this information, we can say that 5/25 cans are root beer cans. To find the percent, we change the fraction into a decimal and then multiply it by 100.
To change 5/25 into a decimal, we divide the numerator and denominator.
5/25=0.2
And we multiply the decimal by 100 to get the percent:
0.2*100=20
Therefore, 20% of Cam’s cans are root beer cans.
I hope this helps!
