There are 43 girls and 25 boys in the Valley View Middle School chorus. Part A
Write the ratio of girls to boys and the ratio of boys to girls in the chorus.
Part B
Are the ratios you wrote part to part or parts a whole ratios?
Part C
Write the ratio of girl in the chores to the total number of chores member and the ratios of boys in the chorus to the number of chorus members.
Part D
Are the ratios you wrote Part two part or part to whole ratios?
Part E
Which is greater the ratio of girls to the total number of course members or the race you to boys to the total number of course member explain your reasoning

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

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.
