Hello,
The GCF is -10m^2 n^7.
Answer:
20km/h
Step-by-step explanation:
use the speed distance time formula
it takes 45mins to get to the park which is 0.75 of an hour
20/0.75 = 20km/h
Answer:
1. k= 6
2. z= 4
Step-by-step explanation:
1. Given equation is:
6k+8=-10
We will solve the equation.
Subtracting 8 from both sides
6k+8-8 = -10-8
6k = -18
Dividing both sides by 6
![\frac{6k}{6}=\frac{-18}{6}\\k=-3](https://tex.z-dn.net/?f=%5Cfrac%7B6k%7D%7B6%7D%3D%5Cfrac%7B-18%7D%7B6%7D%5C%5Ck%3D-3)
2. Given equation is:
5z-5=15
We will solve the equation.
Adding 5 on both sides
5z-5+5=15+5
5z=20
Dividing both sides by 5
![\frac{5z}{5}=\frac{20}{5}\\z=4](https://tex.z-dn.net/?f=%5Cfrac%7B5z%7D%7B5%7D%3D%5Cfrac%7B20%7D%7B5%7D%5C%5Cz%3D4)
Hence,
1. k= 6
2. z= 4
250% 35 divided by 14 equals 2.5 then you convert that into a percentage
