Answer:
The sum will be whichever number has the greater value.
Step-by-step explanation:
Let's say you have (-2) + 4 = ?
The number with the greater value is 4.
So the sum of your answer would be a positive, since the greater number has a positive sign.

3x-5=8x-60
55=5x
x=11
Answer:
The length of the shorter piece=0.35 m
Step-by-step explanation:
Let the lengths be as follow;
Shorter piece=x
Longer piece=15 cm longer than twice shorter piece(x)
Since 1 m=100 cm, 15 cm=15/100=0.15 m
Longer piece= (2×x)+0.15=2x+0.15
Total length=1.2 m
Total length=shorter piece+longer piece
Replacing;
1.2=x+2x+0.15
3x=1.2-0.15
3x=1.05
x=(1.05/3)=0.35
The length of the shorter piece=x=0.35
Answer:
x = 6

Answer:
<h2>d=4</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
11=−d+15
Step 1: Flip the equation.
−d+15=11
Step 2: Subtract 15 from both sides.
−d+15−15=11−15
−d=−4
Step 3: Divide both sides by -1.
−d/−1=−4/−1
