So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5
your welcome!!!! :)
Answer:
The answer is at 8:00 o’clock.
Step-by-step explanation:
So the Martinez family started 30 min after the Smith’s family. Smith’s family started one hour before Carson’s family. So it means the Smith’s family started at 7:30 and Martinez family started 30 min later. It means at 8:00 o’clock.
Answer:
x = 181 and y = 97
Step-by-step explanation:
let called the first number is x
the second number would be called y
We are given that:
x + y = 278 (1)
x = y + 84 (2)
Let change x in (2) into (1):
y + 84 + y = 278
2y + 84 = 278
Subtract 84 from both side, we got:
2y + 84 - 84 = 278 - 84
2y + 0 = 194
Divide both side by 2, we got:
2y / 2 = 194 / 2
y = 97
Because y = 97 and x + y = 278 so x would equal:
x + 97 = 278
Subtract 97 from both side, we got:
x + 97 - 97 = 278 - 97
x + 0 = 181
x = 181 and y = 97
Hope this helped :3

I hope that helps.
The simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is 53 - w.
<h3>Linear equation:</h3>
Linear equation is an equation in which the highest power of the variable is equals to one.
Therefore, the number of economy-size cars rented in w weeks is represented as follows:
The number of full-size cars rented in w weeks is represented as follows:
where
w = number of weeks
A simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is as follows:
- 152 + 3w - (99 + 2w)
- 152 + 3w - 99 - 2w
- 53 - w
