Eric says he knows 9/10 is 1/10 less than 10/10 or 1 mile so he is going to subtract 1 mile then i had 1/10 back can he use this method to solve the example problem explain

Step-by-step explanation:

According to Eric's opinion, 9/10is 1/10 less than 10/10 or 1 mile.

So, to prove that, he is going to subtract 1 mile and 9/10, to obtain 1/10 back. Let's see if he's right

You can observe that Eric is actually right, he can subtract 9/10 from 1 mile, and that operation will return 1/10 back.

Therefore, Eric can use this method, it's totally correct.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
