The numbers are 5 and 2.
Reciprocals: 5- 5/10
2- 2/10
(2/10)+(5/10)= 7/10
5-2= 3
Answer: 5 and 2
6 years
A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now. This is an exponential function, An exponential function is given by:
Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8
Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2
Therefore:
To find the number of years will it take to reach $20 per month, we substitute y = 20 and find x
x = 6 years to the nearest year
Your key word is divide. You'll want to divide your 6 pizzas by your four friends, than most likely convert it to a fraction (unless your teacher accepts decimals.), message if you need more help.
You'll use the chart to start your equation. There are 2000 grams to a kilogram. One batch is 1425grams. To get 2 kilograms she needs 2000 grams. So 2000-1425= your answer. For question 2, there are 1000 ml in 1 Liter. Use this information to see which will hold more liquid, 2 bottles or 8 cans.
