Answer:
10 feet
Step-by-step explanation:
define variables:
y= height of the boards
x= distance to corner
we are trying to figure out what x is since we know the height of the board
4= 0.4x
divide both sides by 0.4
10=x
Answer:
5
Step-by-step explanation:
5 x 8 = 40
3.50 x 4 = 14

It's ALWAYS TRUE
Answer:
see the explanation
Step-by-step explanation:
we know that
When solving a system of equations graphically, the solution is the intersection points both graphs.
so
You need to estimate the solution when:
a) both the x- and y-values for the intersection point are not integers.
b) the value of at least one coordinate is between integers.
c) the intersection point does not fall on a grid line.
The price up to 20% was
120*40/100=48 $
The cost down by 20% is:
48*80/100=3840/100=38,4 $
38,40=40*x/100
x=38,4*100/40=3840/40=96 %
