Answers to numbers 2 and 3

BARSIC [14]

For both of them you just make them into fraction.
For #2
$\frac{36}{120}$
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100

so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100

The answer is 30%

For number #3
you simply put 63 over 240
63
-----
240
$63 \div 3= 21$
$240 \div 3 = 80$
$\frac{21}{80}$
21
----
80
is that answer because it can't be simplified
after that

I need help with this problem <br><br><br> -8(2v-2)=-4(7+5v)

Ne4ueva [31]

Answer: I'm not sure if this is right or not but I got U = 4

Step-by-step explanation: -8(2v-2)=-4(7+5u. So first I distributed and got -16v -16 = 28 + 20u. And then I added 16u with 20u I added because you change the sign like if it's a negative you make it a positive so once you do 20u+16v you should get 36 and then on the other side it should be -16+16 which equals -16u from when you distributed so now you should have -16u=28+36 so now you would add 28 the 36 since they both are positives and have no variables which you should get 64 and then on the left you should have 16u. So it looks like -16u=64. And then now you would divide -16u on both sides and the side with the variable put it or v whatever variable you want to use and then do 64 divided by 16 and you should get 4.

If the distance from R to S is only half then the other half is S to T. The distance between R and S is (5,2). that should give you the answer
