Answer:
correct answer: Bob's hose required alone 33 hours and Jim's hose required alone 66 hours
Step-by-step explanation:
Given:
Bob's hose time = 50% of Jim's hose time ⇒
⇒ Jim's hose time = 2 · Bob's hose time
Let be x Bob's hose time and 2x Jim's hose time
The following equation will solve the problem:
1/x + 1/ 2x = 1/22
The common denominator for both fractions is 2x, so we will multiply the first fraction by the number 2 and get:
2/2x + 1/2x = 1/22 ⇒ 3/2x = 1/22 ⇒ x = 3 · 22 / 2 ⇒ x = 3 · 11 = 33 hours
Bob's hose time x = 33 hours and
Jim's hose time 2x = 66 hours
God is with you!!!
First find the common denominator. It would be 24. For 8 to get to 24 you have to multiply it by 3. So 8*3=24 and 5*3=15. For 6 to get to 24 you have to multiply it by 4. So 6*4=24 and 1*4=4. Our fractions are now at 15/24 and 4/24. 15+4 is 19 and 15-4 is 11. Your answers are 19/24 and 11/24.
Answer:
The answer is: the second one
Step-by-step explanation:
(2x + 2)/y = 4w + 2
pass y to the right side 2x + 2 = y(4w + 2)
expand 2x +2 = 4wy + 2y
pass 2 to the right 2x = 4wy + 2y -2
pass 2 to the right x = (4wy + 2y - 2)/2
simplify x = 2wy + y - 1 or = 2yw + y -1
Answer:
the vertex is of the equation is (3,2)
Answer:
x=14
Step-by-step explanation:
17=x+3
-3 -3
14=x
subtract 3 on both sides
