Answer:
y=-10x
Step-by-step explanation:
y=-10x
y/x=-10
Well if 1/16 costs $2 then you do 16*2 to find the cost of 16/16 aka 1 pound. 16*2=32 so the answer is x = 32.
Answer:
9
Step-by-step explanation:
14/y=112/72
simplify 112/72 into 14/9
14/y=14/9
y=9
V² - 2v = 3
v² - 2v - 3 = 0
v = <u>-(-2) +/- √((-2²) - 4(1)(-3))</u>
2(1)
v = <u>2 +/- √(4 + 12)</u>
2
v =<u> 2 +/- √16</u>
2
v = <u>2 +/- 4</u>
2
v = <u>2 + 4</u> v = <u>2 - 4</u>
2 2
v = <u>6</u> v = <u>-2</u>
2 2
v = 3 v = -1
Remark
The best way would be to make a duplicate of this page and cut out the shapes. Then find out which ones fold into a cube. It would also be the most time consuming.
The second best way is to imagine how each flat surface would fold to make a cube. I think C would and D would. I don't think the other 2 would.
