Answer:
x=155
Step-by-step explanation:
(2x-120)+10=180
or,2x-130=180
or,2x=180+130
or,2x=310
or,x=310÷2
x=155
The answer would be D. -11i and 11i

Answer:
2
Step-by-step explanation:
From the Question:
For daily supply of oxygen for a particular multicellular organism 625, square feet of lawn I needed.
Simply, 1250 feet of lawn will make supplies for:
= 1250/ 625
= 2
2 multicellular organism.
5 is A, because it's the only number that is whole when square rooted.
6 is confusing because it only gives you one number per answer, unless you are to add the two distances together? Then it would be 7 because X's distance is +4 and Y's distance is +3
I do not have an answer for 7
8 is 3.7 (or C)
9 is an easy one. Find out what the L and W is, and since it's a square we only need to find one of them. We square root the area and we are given 14.96662955, if rounded we get 15. So the answer is A
10 I don't understand the "estimate" for a square root number, I was not taught that.
