Answer:
Ttt
Step-by-step explanation: but it was the first one that we used in it was a bit too small and not enough for us and we had a good idea and I didn’t know if we could go in there and then I was going there with it but it wasn’t too much for us to go to the park park in a bit so it wouldn’t let us ioy it was just
The guy said he was in charge of the truck and he said it wasn’t the best truck driver but I didn’t want it in the car and I said I didn’t know if it would be worth the drive to get there
First is to make equations for both sides.
Let x be the number of the miles.
a be the charge of the first company
b be the charge of the second
a=$35+$0.25(x), b=$40+$0.20(x) .
then a=b
Substitute the equations
$35+$0.25(x)=$40+$0.20(x)
$0.25x - $0.20x = $40 - $35
$0.05x = $5
x= $5/$0.05 , cancel out the unit.
x= 100
To justify substitute x to both the equations a and b.
a= 35 + 0.25(x)
a= 35 + 0.25(100)
a= 35 + 25
a= $60
b= 40 + 0.20(x)
b= 40 + 0.20(100)
b= 40 + 20
b= 60
a=b
60=60.
Answer:
8 hours for math and science each
Step-by-step explanation:
4 x 8 = 32
3 x 8 = 24
32 + 24 = 56 hours
- You need to keep what you multiply, (ex. 8), the same as you work through this problem.
- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.
