Emma scored 4 points more than twice number of points teagan scored. Emma scored 3 points. How many did teagan score
Snowcat [4.5K]
Let's write T for Teagan's score and E for Emma's score.
Also, let's write an equation

E = 2T + 4
E = 3
2T + 4 = 3
subtract 4 from both sides
2T = -1
divide both sides by 2
T = -1/2

To see of this is correct:
2T + 4 = 3
2(-1/2) + 4 =?= 3
-1 + 4 =?= 3
3 = 3

Hope this helps

What is the surface area of a cube whose edges are 11 inches long?
Dennis_Churaev [7]
Surface area is the total area of the surface. A cube has 6 surface, and each surface is the same. Each surface is a 11 by 11 square. Therefore there will be 6 11in. x 11in. surfaces. The math would be 11x11x6 =726.

#3 is correct at 120.4

#4 is 15/8...because 3/4+3/4=6/4 (for 20 doors) plus 3/8 (which is half of 3/4 for 5 more doors) equals 15/8 gallons or 1.875 gallons

#5 is $812.50 because if 50 shares cost $125, 325 shares (125×6.5) equals 812.50
