Answer:
n= 4
Step-by-step explanation:
3 multiplied by n is 3n.
3 multiplied by -5 is -15.
so 3n-15= 7-2(n+1)
7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.
3n-15=7-2n-2
then move the variables to one side and numbers to the one side.
3n+2n=15+7-2
*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.
so 5n=22-2
5n=20
5 multiplied by 4 is 20 so n is going to be 4.
N=4
You put number nine in the form of y=kx
For number 7 because 9 is the number of small triangle and 99 is for the bigger one so you can say 9 * 11 = 99 so 10 * 11 = 110 = x
and for number 8 because the small triangle has the same sides so the bigger one should have too so x = 100 :)))
hope this is helpful
have a nice day
The quotient of 2/7 is 2 ÷ 7 = 0.285714
And 3/5 is 3 ÷ 5 = 0.6
[(-5)^3]^2
= (-5)^(3*2)
=(-5)^6
answer
(-5)^6
