A pizza had 9/10 left before Lucas ate 4/5 of the pizza. How much pizza is left over
Norma-Jean [14]
1/10 is left.

Explanation:

First we need to find a common denominator. Since 5×2=10, if we multiply 4/5 by 2/2, we will be able to subtract that from 9/10.

4/5×2/2= 8/10. Then if we subtract that from the 9/10 left of the pizza, we get 1/10, the amount remaining.

Hope this helps :)

How do I solve this equation n^2=18n+40.
Readme [11.4K]

Answer:

n = 20 or n = -2

Step-by-step explanation:

Solve for n over the real numbers:

n^2 = 18 n + 40

Subtract 18 n + 40 from both sides:

n^2 - 18 n - 40 = 0

The left hand side factors into a product with two terms:

(n - 20) (n + 2) = 0

Split into two equations:

n - 20 = 0 or n + 2 = 0

Add 20 to both sides:

n = 20 or n + 2 = 0

Subtract 2 from both sides:

Answer:  n = 20 or n = -2
