Hey there!
Let's write this as an equation, with n representing the unknown number.
0.5n-35=14
First, we add 35 to both sides.
0.5n=49
We divide both sides by 0.5.
n=108
Therefore, your number is 108
I hope this helps!
Answer:
Consider the number of children to be x.
So, 144 coins were divided amongst x children.
For x-3 children, each child would have 16 coins
So, (x-3)*16=144
Solving for x, x-3=144/16
or x-3=9
or x=9+3=12
Answer is 12
Answer:
A
Step-by-step explanation:
The y-intercept is -1, so the answer is either A or C
Since the line is going down when you read left to right, then it must have a negative slope. A has a slope of -1/3 and C has a slope of +3. Therefore, A is the answer
2(4+2x)≥5x+5
4+2x≥5/2x+5/2 (divide both sides by 2)
3/2+2x≥5/2x (subtract 5/2 from both sides)
3/2≥1/2x (subtract 2x from both sides)
3≥x (multiply both sides by 2)
or x≤3
Hope this helps
