Solve the equation for x 6x + 1 - 4x = 2+ x + 4
Nina [5.8K]
First simplify all of the numbers with common variables (or those without)

6x - 4x + 1 = 2 + x + 4

2x + 1 = x + 6

subtract x from both sides to move x to one side

2x (-x) + 1 = x (-x) + 6

x + 1 = 6

subtract 1 from both sides to isolate the x

x + 1 (-1) = 6 (-1)

x = 6 - 1

x = 5

5 is your answer for x

hope this helps

marin [14]

Answer:

96 laps

Step-by-step explanation:

2 hours = 2 * 60 = 120 minutes

So now the question would be as given below:

8 laps in 10 minutes so how many laps in 120 minutes.

Since, no. of laps and minutes are in proportion.

\therefore \:  \frac{8}{10}  =  \frac{x}{120}  \\  \\ x =  \frac{8 \times 120}{10}  \\  \\ x =  \frac{960}{10}  \\  \\ x = 96 \:

Amy worked 16 hours more than Brayden last month. If Amy worked 8 hours for every 7 hours that Brayden worked, how many hours di
marishachu [46]

Answer:

Amy worked for 128 hours while Brayden worked for 112 hours

Step-by-step explanation:

Given

Let A represents Amy and B represents Brayden

A = 16 + B ------(1)

A:B = 8:7------- (2)

Required

Find A and B;

Convert (2) to fractions

\frac{A}{B}  = \frac{8}{7}

Cross Multiply

7 * A = 8 * B

7A = 8B

Substitute A = 16 + B in the above expression

7(16 + B) = 8B

Open Bracket

7 * 16 + 7 * B = 8B

112 + 7B = 8B

Subtract 7B from both sides

112 + 7B - 7B = 8B - 7B

112 = B

B = 112

Recall that A = 16 + B

Hence, A = 16 + 112

A = 128

<em>This implies that Amy worked for 128 hours while Brayden worked for 112 hours</em>
