4 ice cream cones cost $10.00. At this rate, how much do 3 ice cream cones cost?

Since you dont know the unknown money per cone we make it an equation:

4c(unknown money per cone) = $10

Let's divide both sides by 4

C = 2.50, now we found out the cost of 1 cone.

Since there are 3 cones we multiply by 3,

2.50 x 3 = $7.50

Step-by-step explanation:

4c=10

4c/4=10/4

c=2.5

3c=x

3(2.5)=x

7.5=x

answer: 2/4

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
