I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
C. 17
Why:
Divide 100 by 6, round the answer and you should get 17
I'll solve it algebraically
x+y=4
x-3y=12
multiply first equatoin by -1 and add to second
-x-y=-4
<u>x-3y=12 +</u>
0x-4y=8
-4y=8
divide both sides by -4
y=-2
sub back
x+y=4
x+-2=4
add 2 to both sides
x=6
x=6
y=-2
(6,-2)
Here ya go. I hope this helps! :) (It was much easier to do this than to try and type it out, in my opinion)
Answer:
20%
Step-by-step explanation:
1/5 of 1 hour = 20 minutes
so 1/5 = 20%
25% + 20% = 45%
0.35 = 35%
45% + 35% = 80%
100% - 80% = 20%
Answer = 20%
Hope this helps!
