Answer:
60 feet
Step-by-step explanation:
We know that a triangle has 3 sides, in this case we will call them a, b and c.
It tells us that everything is material, it measures 20, that is:
a + b + c = 20
They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:
border material need = 3 * a + 3 * b + 3 * c
common factor 3:
border material need = 3 * (a + b + c)
border material need = 3 * 20
border material need = 60
Which means that she needs a total of 60 feet of material.
Answer:
<h2>cherry pie = 5</h2><h2>lemon pie =10</h2>
Step-by-step explanation:
Step one:
let cherry be x
and lemon be y
the systems of the equation for the solution is given as
4x+y=30-----------1
8x+6y=100------2
Step two:
solve the equation simultaneously by substitution we have
4x+y=30
y=30-4x
put y=30-4x in equation 2
8x+6(30-4x)=100
8x+180-24x=100
8x-24x=100-180
-16x=-80
x=80/16
x=5
put x=4 in y=30-4x
y=30-4(5).
y=30-20
y=10
