Hi there! :)
<u>Answer:</u>
The good answer is the top left one, which is:
2x -1(5 - 3x) = 4x +2
2x - 5 + 3x = 4x + 2
Step-by-step explanation:
2x <u>- 1</u>(5 - 3x) = 4x + 2
The correct first step is to distribute the "-1" to the entire parentheses:
-1 × 5 = <u>-5</u>
-1 × -3x = <u>3x</u>
Once this first step is done, you are left with an equation looking like this:
2x - 5 + 3x = 4x + 2
Which is the top left answer for you!
There you go! I really hope this helped, if there's anything just let me know! :)
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!!!
Is the question what c is?
if so just subtract 3 from 10
3-10 = -7
therefore c = -7
hope that helps :)
You have to line them up for example 1 is in a straight line and so is 3 and 5 you can choose between 3 and five but what about the middle 4.
I believe the answer is 42 % which would be .42
