Can someone please answer these questions!

For number one A we need to multiply 5x5 because exponents make you multiply the base number by the exponent the ammount of times the exponest value is. This would give is 25-6 which equals 19

number 1 B we need to add the 8 and the 3 to give us eleven over five. thats the simplest answer to this question

2a we need to multiply the 5 into the parenthesis

then we add. The answer would be 28

for 2b the answer would be 9 2/9

ill let you solve the rest. hope this helped. dont forget to leave a heart give it 5 stars and make it the brainliest answer!!

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.
