2 answers:

8 0

First make the denominator into a 100... to do this you need to multiply the denominator (10) by 10... do the same with the numerator to give you 70. So your percent is 70% because it is a value over 100.

Consider the following pair of equations: y = −2x + 8 y = x − 1 Explain how you will solve the pair of equations by substitution

Darina [25.2K]

Answer:

(3,2)

Step-by-step explanation:

y = −2x + 8

y = x − 1

Substitute the second equation into the first equation for y

y = -2x+8

x-1 = -2x+8

Add 2x to each side

x-1+2x = -2x+8+2x

3x -1 = 8

Add 1 to each side

3x-1+1 = 8+1

3x =9

Divide by 3

3x/3 = 9/3

x=3

Now find y

y = x-1

y =3-1

y=2

Prime factorization of 891

Fantom [35]

So exg
prime factorization is finding the prime number that will multiply to getthat tnumber
normally we exclude the number 1
so prime factor of 6=2 times 3
note:2*3 menas 2 times 3

so 891
it is odd so not divisible by 2
try 3
891/3=297
3*297=891
factor further
297
try 3
297/3=99
3*3*99=891
99
divide by 3
33
3*3*3*33
33
divide by 3
11
3*3*3*3*11
11 is prime so the prime factoization is
3*3*3*3*11 or 3^4*11
