v + 9 / 3 = 8
v + 9 = 24
v = 24 - 9
v = 15
If you have any questions on how I got to this solution, please ask. :)
1. Let x be the original amount of baseball cards,
2. half of x was lost so x divided by 2.
3. you buy 18 cards to replace some that were lost
4. You can find the awnser by subtracting 18 from 30, which is 12.
5. Now lets remember that half of your cards were lost. meaning that 12 is only half of what you started with.
6. 12 times 2 would be 24.
7. The Awnser is 24
8. To check your work, you can say x=24, 24 divided by 2 is 12, and 12 plus 18 is 30.
(2.6 * 10^9) / (1.3 * 10^2) =
(2.6 / 1.3) * (10^9) / (10^2) =
2 * 10^7 or 20,000,000 <===
Add the 7 and 4, which =11.
multiply times the 5, =55
and 20-55= -35
Answer:
7 pizzas
Step-by-step explanation:
Using the formula for slope (rise/run) we can calculate how much one pizza cost.
dollars per pizza.
Take the $11 per pizza and divide it by $80 to get 7.2727 pizzas. Since you can not have .2727 of a pizza you round down to 7 pizzas.
