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=18
Step-by-step explanation:

Here you have to use cross multiplication
Answer:
25% = (p) 1/4 = picking a number 9.
(p) 1/4 = 0.25 (results getting a number more than 8 or just getting 9
This is add rule from the 4 card set.
1/4 + 0 + 0 + 0 = 1/4
Because each (P) is equal and shows (P); 1/4
there are 1 event so 1/4 + 0= 1/4 = 0.25%
Step-by-step explanation:
0.25 x 100 = 25%
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
(23 x 2) - 12 = x
We need 2 cookies per student, so multiply the amount of students by 2. which is 23 x 2. Then because you already baked 12 subtract 12 from the original amount you needed to bake. Which is 46 - 12. Oh and if you wanted the answer, it's 34.
