Answer:
-3
Step-by-step explanation:
Note the right side of the equation. There is a negative sign outside of the parenthesis. Distribute the negative sign to all terms within the parenthesis:
x + 3 = - (-x + __)
x + 3 = x - ___
Note:
1) When multiplying a negative and positive together, the answer will be negative
2) When multiplying a negative and negative together, the answer will be positive:
x + 3 = x - ___
Note the equal sign, this means that the two side of the equation must equal. This means that the only answer choice is -3:
x + 3 = x - (-3)
x + 3 = x + 3 (True)

Answer:
16
Step-by-step explanation:
ratio is 5:4:1
David: Malachy: Paul
David gets 20 (that is 4 times more than the original ration. so need to multiply everything by 4)
4*4=16
1*4=4
new ration- 20:16:4
So David gets 20
Malachy gets 16
Paul gets 4

Answer: i think its 7 cm pretty sure
8/5x = 1
or
1.6x = 1
Work:
Add 7/3x and 1/3x to make 8/3x. Equation: 8/3x = 1 + 5/3x
Divide 8/3x by 5/3x, looks like 8 over 3 times 3 over 5. 3s cancel each other out, leaving 8/5x. Equation: 8/5x = 1
If needed to be simplified, 8/5 = 1.6.
