Answer:
B negative
Step-by-step explanation:
use real numbers?
n is +9
m is -11
m/n * (-m*n^2)
-11/9 * (11*81)
-11/1 * (11*9)
-11 * 99
-1089
X^2 + 12^2 = 13^2. (‘^2’= to 2nd power)
X^2 + 144 = 169
- 144. -144 (make X term by itself)
X^2 = 25 (to undo “squared”, find root.)
X = 5
Answer:
1/61
Step-by-step explanation:
reciprocal just means you flip it. since 61 is a whole number. it would be 61/1 but you flip that over and its 1/61.
Answer:
$46.27
Step-by-step explanation:
we know that
The average cost of 5 gallons of regular unleaded gasoline in the United States was $14.46
using proportion
Find out the average cost for 16 gallons of gas
Let
x ----> the average cost for 16 gallons of gas
![\frac{5\ gal}{\$14.46}=\frac{16\ gal}{x}\\\\x=16(14.46)/5\\\\x=\$46.27](https://tex.z-dn.net/?f=%5Cfrac%7B5%5C%20gal%7D%7B%5C%2414.46%7D%3D%5Cfrac%7B16%5C%20gal%7D%7Bx%7D%5C%5C%5C%5Cx%3D16%2814.46%29%2F5%5C%5C%5C%5Cx%3D%5C%2446.27)
A= 13 because B=5 and C=12
Hope this helps
