Answer:
d. 393-159 hope this helps and that is the answer
If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.
8x-16=8x+k
If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
<u>Answer:</u>
- For 15 pens, the cost is $7.2
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
Divide the RHS:
- => 1 pen = 3.84/8
- => 1 pen = 0.48
Multiply the RHS:
- => 15 pens = 0.48 x 1
- => 15 pens = $7.2
Hence, <u>for 15 pens, the cost is $7.2</u>
Hoped this helped.
