PLEASE HELP ASAP!! 180x=2(30÷3)+17-5•11+2÷1 = ?
Rainbow [258]

Answer:

x = -4/45

Step-by-step explanation:

180x=2(30÷3)+17-5•11+2÷1

We need to simplify the right hand side.  The first step is the parentheses

180x=2(10)+17-5•11+2÷1

Then multiply and divide, working left to right from the equals sign.

180x=20+17-5•11+2÷1

180x=20+17-55+2÷1

180x=20+17-55+2

Now we add and subtract  working left to right from the equals sign.

180x=37-55+2

180x =-18+2

180x = -16

Divide each side by 180

180x/180 = -16/180

x = -4/45

Area question..........
OverLord2011 [107]
Well in area you multiply and perimeter you add, so right now you are multiplying the measures of the triangle, So you can either write out the problem and solve it or use a calculator to get you answer, but I would say to solve it because you never if the calculator could be wrong, so if you wanna write it out then you write 9 then put the 14 under it and put the 5 under 14 but under the 4 of 14, so basically you are just going to multiply 9 by 14 to get 126 then multiply 126 by 5 to get 630, so now 630 is your final answer
