<em>multiply both sides by 5 </em> 3(15k+10)=5(12k-9)
<em>get rid of the brackets</em> 45k+30=60k-45
<em>take away 45k to both sides</em> 30=15k-45
<em>plus 45 to both sides</em> 75=15k
<em>divide both by 15</em> k=5
So first we need to find the area of both using a=3.14*radius*radius
to find the radius we need to divide 35 by 2 (large) and 30 by 2 (medium)
lets do the large first since the raidus is 17.5 we put it into a=3.14*17.5*17.5
and then we get 961.63, for the medium we do a=3.14*15*15 which is 706.50
now for the large 961.63 * 2 is 1923.26 and the price is 19.99
for the medium we do 706.50 * 3 which is 2119.5 and costs 24.99
So the medium pizzas are a better deal
Answer:

Answer:
<u>B.(-5.5; 0)</u>
Step-by-step explanation:
Answer:
It has a scalar factor of 2.5
Step-by-step explanation:
You can just look at the bottom, the first shape has a bottom of 4 square while the second image has a bottom of 10 squared. You can divide the two to get the scaling factor. 10/4 = 2.5
You can also see one of the side square
