Given <span>20 yards for $30.00, unit rate = $30 / 20 yards = $1.5 per yard
Given 40 yards for $45.00, unit rate = $45 / 40 yards = $1.13 per yard
Given 50 yards for $70.00, unit rate = $70 / 50 yards = $1.4 per yard
Given 65 yards for $85.00, unit rate = $85 / 65 yards = $1.31 per yard
The best deal is the cheapest rate which is 40 yard for $45.00

Answer:
x = 4
y = 10
Step-by-step explanation:
29x - 3 + 15x + 7 = 180 (Linear Pair)
44x + 4 = 180
44x + 4 = 180 - 4
44x = 176
x = 4
29(4) - 3
116 - 3
113
13y - 17 = 113 (Alternate Exterior Angles Theorem)
13y - 17 + 17= 113 + 17
13y = 130
y = 10
Answer:
D. -8
Step-by-step explanation:
0-4=-4
0-4=-4
-4 + -4 = -8
As the only prime factor of denominator is
2
, in fact there are three twos (
2
×
2
×
2
) we can can convert the fraction
7
8
by multiplying numerator and denominator by
5
×
5
×
5
.
Hence,
7
8
=

=
0.875
(This is always possible if only prime factors of denominator are
2
's and
5
's - just multiply by as many
5
's and
2
's).
