Put into mathematical equation: one fifth the sum of 7 and a number

(x+7)·.2

Step-by-step explanation:

The sum of x and 7 is x+7. The word sum indicates addition. Then it says multiply by 1/5, so i converted it to decimal which is .2

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
