Answer:
3. A linear equation must have a constant rate of chang. So, let's start. WE will Have X Represent the money he has in his savings account per month, M will represent how much money he makes each month. And the x values (X) can't have the same two numbers
X M
550 200
750 400
950 600
1150 800
1350 1000
1550 1200
1750 1400
1950 1600
2150 1800
As we can see in the equation above that it takes Peter approximately 9 months to get 2000 in his bank acc.
4. The answer to this question is 37.5 because we do 8*37.5 to get 30,00, and 20,00 + 30,00 = 50,00. So, it takes us 37.5 years to get to 50,00 people.
5. Logan will have 50 because 75*12 - 900. 950 - 900 = 50.
6. So, $50 per month, plus 75*0.10
The answer is 7.5
50 + 7.5 = 57.5 dollars a month you would have to play according to the Verizon plan.
7. 400*15 + 40 will give us our answer to this one.
400*0.15 = 60. 60 + 40 = 100
Now, back to Verizon
400*0.10+50 will give us our answer for this one
400*0.10 = 40. 40 + 50 = 90.
So, if you sent 400 text messages per month then you would prefer Verizon because Verizon would be 90 per month but T-Mobile would be 100 per month
1. First we have to do 1.5*20 because the plant grows 1.5 cm each day for 20 days.
1.5 * 20 = 30.
Now, we do 8*30 because 8 is the current height times the growth of it in 20 days.
8*30 = 240.
So, the plant's height after 20 days is 240 cm.
2. He loses 5 pounds a month. 249 - 5 = 244, 239, 234, 229, 224, 219. So, counting up how many times I subtracted by five, it takes him 6 months to get to 220 pounds.
Hope these help!
