Answer: c/2-4
Step-by-step explanation:
This is what I get :
1/2(c-8)
Distributed property
1/2(c) + 1/2(-8)
Do c and -8 as a fraction with denominator 1 solve across
1/2×c/1+1/2×-8/1
Here you can only divide -8by 2
C/2-8/2
To get -4
C/2-4
You can't go further
Here is what I did to find the answer:
20% of n is 3520% * n = 3520/100 * n = 35n = 35 * 100 / 20n = 175
50% of 175 = 50% * 175 = 50/100 * 175 = 87.5
The correct answer would be 87.5.
16 * 12 = 192 dimes should be your answer.
Well using elimination is easy because they basically did it for you.
4x-5y=-6
2x+5y=12
The postive 5y and negative 5y cancel out because -5y plus 5y is zero.
so you are left with
4x=-6
2x=12
Add these together
6x=18
divide both sides by 6 and Solve to find your x
x=3
Now we have to eliminate x to find y.
we multiply the second equation by -2 so it can cancel out so
(2x+5y=12)-2
-4x-10y=24
Add the equations together
4x-5y=-6
-4x-10y=24
You are left with -15y = 30
Solve for y
y = -2
So your final answer for the elimination would be
(3,-2)
Answer:
4a: 1
4b: 6, -6
Step-by-step explanation:
4a. (3 - 5)= -2; (9 - 6)=3
(-2 + 3) = 1
4b. We aren't told which cards Jesse pick up, only that they didn't affect his total points. Therefore, the two cards have the same number, but opposite signs. We coluld pick any teo an an example: 6 and -6, or 4 and -4, etc. They don't affect his score since they ccancel each other with a result of zero.
