PLEASE HELP FAST!!!!!!!!

Answer:

Option B. -j = -h/-k is not correct

Step-by-step explanation:

As from the given scenario both the negative signs will be cancelled out giving positive j : -h/-k = -j

First option has: -j = -h/k In this case also the negative sign from both sides would be cancelled out.

Second option has: -h/-k = -j In this case negative signs cannot be cancelled out.

Third option has: h/-k = -j , negative sign would be cancelled from both sides.

Fourth option has: h/k = j , no negative sign on either side.

i hope it will help you!

I cant resolve this equation : 2x = -2x + 8, can you help me please
chubhunter [2.5K]

Answer:

x = 2

Step-by-step explanation:

OK so lets do it together.

2x = -2x + 8

Subtract 8 from both sides

2x - 8 = -2x

Add 2x to both sides

4x - 8 = 0

Add 8 to both sides

4x = 8

Divide each side by 4

x = 2

Check:

4 = -4 + 8

4 = 4

correct

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Assoli18 [71]

Answer:

A. 7 burritos for $51.50

Step-by-step explanation:

22.50/3=7.50

1 burrito cost $7.50

2 burritos will cost $15.00

2×7.50=15

5 burritos will cost $37.50

5×7.50=37.50

4 burritos will cost $30.00

4×7.50=30.00

However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
