Question

Please help I don’t understand why

Answer 1

70

Explanation:

the equation is saying: 6(-5) +100. Multiply first. when multiplying a positive by a negative, you get a negative. 6 times 5 is 30. add the negative sign, and its -30. 100+ -30, is saying, 100- -30. 100 - 30 is 70. hope this helps

Answer 2

k=70

Explanation:

So we know x=-5 so lets replace x with -5 in this equation:

6x+100= 6(-5)+100

6(-5)=-30

-30+100=70

so we know that 6(-5)+100=70

and 6x+100=70

and k=6x+100

so therefore k=70
