Answer:
Solution given
let boys be x and girls be y.
now
according to the question;
x+y=575
and
y=x-54
substituting value of y in equation 1.
x+x-54=575
2x=575+54
x=629/2
x=314.5
Answer:
33.4
Step-by-step explanation:
Ur retirement plan is lower because you are not woroking as much
Answer:
least number of quilts is gonna be 10
Step-by-step explanation:
ok...so profit = revenue - expenses
n = # of quilts
revenue : (the money made from the quilts)
she sold each quilt for 35 bucks......35n
expense : (the money Norma spent on the materials)
the cost of fabric is 13.55 per quilt......13.55n
so ur expression is :
revenue - expenses
35n - 13.55n <==== this is part A
==========================
she wants to make a profit of 200...
P = revenue - expenses
200 = 35n - 13.55n
200 = 21.45n
200 / 21.45 = n
9.32 = n.......gonna have to round up to 10 <==== part B
ok...so 9 quilts is not gonna be quite enough...so shes gonna have to make 10.

Hi,
Let width = w
Length = l
now according to the question
l = 3w+7
Perimeter = 2(w+l) = 462 .... equation 1
Substituting values of l and w in equation 1 we get
462 = 2(w+3w+7)
231 = 4w+7
224 = 4w
w = 56 yards
Now
l = 3w+7
l = 3*56+7
l=175 yards
So width = 56 yards and length = 175 yards
