Write correct if the order of operations is correct otherwise give the correct sequence of operations remember use pemdas
1. 6 x 4 + 3 divide 3 multiply, add, and then divide
2. 15 divide (4 - 1) x 7 subtract, divide, and then multiply
3. 7+ (8+5) divid 5. add, add, then divide

ratio is 2 : 9

the answer is three

13.5 : 3

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.

c and d is your answers.
