16 scarfs because every 4 scarfs takes 5 feet of fabric
(2x+1) (x+7)
I solved it by using the FOIL method, but you get the same answer either way
Answer:
AG = 18
Step-by-step explanation:
The relationship of the segments created is one is 1/3 (shorter) and the other (longer) is 2/3 of the total length.
Lets make x represent AG.
So, 2/3 of x is 12
or
x = 12
Multiply both sides by the reciprocal of
, which is
.
(
)
x = 12 (
) (x is left alone, the fractions = 1 when multiplied)
x = 12 (
) ( 12 times 3 = 36, divided by 2 = 18)
x = 18
Answer:
The system of equations has one solution. The two equations are intersecting lines.
Step-by-step explanation:
if you want to use the substitution method, you would have to plug in y for 12x+2 in the second equation.
2(12x+2)=x+4
next, you have to distribute
24x+4=x+4
subtract 24x from each side
4=-23x+4
subtract 4 from each side
0=23x
divide each side by 23
x=0
now, plug in 0 to one equation.
y=12(0)+2
y=2
the lines intersect at one point, (0,2)
10*9=90
10+10+9+9=38
90-38=52
52 tiles
and 38 feet of base board
