Five times the sum of 1 and some number is -15. what is the number?

Your equation is 5(1 + x) = -15. Using the distributive property, you would get 5 + 5x + -15. Subtract 5 from both sides to get 5x = -20. Divide by 5 to get -4.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the answer is 21%.
