So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
Answer:
We have;
Hours (h), Total cost C
1, 5*1 + 10 = $15
2, 5*2 + 10 = $20
3, 5*3 + 10 = $25
4, 5*4 + 10 = $30
5, 5*5 + 10 = $35
Step-by-step explanation:
The given parameters are;
Kevin's fixed charge for lawn cutting = $10
Kevin's charge for lawn cutting per hour = $5
The total cost, C, for cutting lawn cutting by Kevin is C = 5h + 10
468=40x+18(x-3)
468=40x+18x-54
468=58x-54
522=58x
9=x
I'm not sure if you need to know x at all, if not, the top equation is all you need.
Samuel started out with 21 mowed lawns. 7(months) x 3(lawns) = 21
If he mows 3 lawns per month, then he would have to mow lawns for another 3 months. 3 x 3 = 9.
21 + 9 = 30
Although this is one mowed lawn over the objective, any less would not reach 29.
I'm not really sure what the question is asking, so here's two answers:
He would have to mow lawns for another 3 months in order to mow 29 lawns.
Or, he would have to mow 8 more lawns.
