answer= x=20
Step-by-step explanation:
We have, 35% × x = 7
or,
35
100
× x = 7
Multiplying both sides by 100 and dividing both sides by 35,
we have x = 7 ×
100
35
x = 20
If you are using a calculator, simply enter 7×100÷35, which will give you the answer.
10C6 = 10!/(6!*(10-6)!) = 10*9*8*7/(4*3*2*1) = 210
There are 210 ways to choose 6 from a group of 10.
Answer:
Both lines are not parallel
Step-by-step explanation:
Given as :
Two lines equation are as :
3y - 5x = 9 And y = -
x - 12
First line is now written in eq y = mx + c
Or, 3y = 5x + 9
Or, y =
x + ![\frac{9}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B3%7D)
So, Slop of this line ( m 1 ) = ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
slop of second line ( m 2) is ![\frac{- 5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-%205%7D%7B3%7D)
∵ The slop of both lines are not equal , so the line are not parallel to each other .
Hence Both lines are not parallel Answer
Divide 120 by 2. Given that there are only two people. Split it equally among the 2
8x3 - 8x + 2x2 - 2
8x3 + 2x2 - 8x - 2
