180= x + (180-107)+(x+ 13)

x = 47

Step-by-step explanation:

180 = x + (180 - 107) + (x + 13)

Subtract in the parenthesis.

180 = x + 73 + x + 13

Combine terms.

180 = 2x + 86

Subtract 86 from both sides.

2x = 94

Divide both sides by 2.

x = 47.

Proof:

180 = x + (180 - 107) + (x + 13)

180 = 47 + (180 - 107) + (47 + 13)

180 = 47 + 73 + 60

180 = 120 + 60

180 = 180

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
