Answer:
10x - 15
Step-by-step explanation:
let Emily's be x hrs
Abbey = 3x-5 hrs
Nathan = 2 * Abbey's time= 2(3x-5)
= 6x-10 hrs
Expression= x + 3x-5 + 6x-10 = 10x - 15 hrs
Therefore, 10x - 15 is the EXPRESSION THAT DENOTES THE TOTAL NUMBER OF HOURS SPENT FOR DOING HOMEWORK COLLECTIVELY.
Hi!
We can remove the parentheses.
2m+3+4m+3=0
Simplify by combining like terms.
2m+4m+3+3=0
6m+6=0
Subtract 6 from both sides.
6m+6-6=0-6
6m=-6
Divide by 6 on both sides.
6m/6=-6/6
m=-1
The answer is m = -1
Hope this helps! :)

Answer:

Step-by-step explanation:
<h3>Given inequality:</h3>
-4x + 7 > x - 13
Subtract x to both sides
-4x - x + 7 > -13
-5x + 7 > -13
Subtract 7 to both sides
-5x > -13 - 7
-5x > -20
Divide -5 to both sides
x < -20/-5
<h3>
x < 4</h3>
