Answer:
x = 17.9
Step-by-step explanation:
3 gallons of acid = 100% concentration acid
? (water+acid) gallons = 15 concentration acid
Note: Every gallon of water added reduces the percentage concentration of acid. Therefore, the relationship is inverse proportionality.
Solution:
Total number of gallons (water+acid) = (3*100)/15 = 20 gallons
Therefore, gallons of water = 20-3 = 17 gallons
Answer
Cameron forgot to do the same thing to the 9. Instead of dividing 3 by 3 and 9 by 3 he only divided 3 by 3.
Step-by-step explanation:
3/7 × 4/9
You can divide the 3 and 9 by 3 so you get 1/7 × 4/3.
Then you do 4 × 1 and 7 × 3.
Correct answer is 4/21
Answer:
I believe the answer may be x= 24.5 I'm not certain though
Step-by-step explanation:
The angles inside the triangle must all add up to 180 so we can subtract 80 from 180 to get 98. Now I'm assuming the two undefined angles are equal because of the two angle bisectors that create the second triangle. If I'm correct in assuming that them we can divided 98 by 2 to get 49 which would be the measurement of both bottom angles. Since there's a line bisecting both of them we would then cut that number in half to get 24.5. I hope this helped, I'm not fully certain of this answer though.
Answer: the equivalent equation is found by distributing the 1/4 to get 4+3x=28
the first step is subtract 4 to both sides
the second step is divide both sides by 3
the answer is x=8
