Answer:
33% off the regular price
Step-by-step explanation:
Lets give these a variables to help us better understand this concept
In our scenario lets say the price is $10.00 and you get 10 milliliters prior to the special, this is arbitrary as any values would do
33% extra free
For the 33% extra free deal you get 3.3 milliliters more for $10 for a total of 13.3 milliliters [Math behind this solution: <em>(10*.33)+10</em>]
<u><em>So now to know how much you're getting per dollar:</em></u>
13.3/10 = 1.33 ml per dollar
33% off the price
This basically means 67% of the actual price so with that being said
you'd be paying $6.7 for 10 ml. This means you get 1.49 ml per dollar
Compare
1.33ml vs 1.49ml
1.33 < 1.49 so thus 33% off the price is a better deal
Justin can make 25 scraves with 15 balls of yarn
<h3><u>Solution:</u></h3>
Given that Justin can make one scarve for 3/5 of a ball of yarn
He purchases 15 balls of yarn
<em><u>To find: number of scarves Justin can make</u></em>
Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn
Thus he can make 25 scraves
Answer:
∆<em>LMN</em> ~ ∆<em>LQR</em>
Step-by-step explanation:
All you have to do is match their similar corresponding angles.
* These are congruent by the Angle-Angle Similarity Postulate, where at least two angles of both triangles are congruent, which in this case is ∠<em>L</em> [Vertical Angles Theorem] and ∠<em>Q</em> & ∠<em>M</em>. This obviously gives us our third side in each triangle, which must sum up to 180° altogether, therefore you have your answer.

If he has 9 rows of equal length there are 3 chairs left over.
If he has 7 rows of same length there are 19 left over.
It's important to note that these two setups have the same number of chairs. So we can make an equation out of it.
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
5x+2x-6=-2x+2
7x-(-2x)-6=2
7x+2x=2+6
9x=8
x=8/9
