Dear SailorMars, #4's question is very convoluted so I won't show you how to do it. Luckily, I do know how to do #5 and #6. With #5, multiply 8 5/6 by two to get 17 2/3, then do 50-17 2/3 to get 32 1/3 ft of tape. With #6, add 11 1/2 and 6 4/5 to get 18.3 gallons of gas, then do 18.3-3 3/10 to get 15 gallons of gas used.
Hey there! I'm happy to help!
We have 110 minus a certain percent of 110 equals 88. Let's call this percent p and solve.
110-110p=88
We subtract 110 from both sides.
-110p=-22
We divide both sides by 110.
p=0.2
Therefore, the percent decrease is C) 20%.
Have a wonderful day! :D
2x +4 (0)=12.4
2x=12.4
x=6.2
2(0) +4y=12.4
4y=12.4
y=3.1
Answer:
C: 4
Step-by-step explanation:
4x+3=6x-5
Add five to both sides
4x+8=6x
Subtract both sides by 4x
8=2x
Divide both sides by 2
X=4
