40-15=g so they scored 25 this year and 25+15=40
Hi there!

Knowing that one cube has side-lengths of 1/2, we can calculate the dimensions for the prism:
Length: 1/2 × 5 = 2.5 cm
Height: 1/2 × 3 = 1.5 cm
Width: 1/2 × 2 = 1 cm
Use this formula to solve for the volume:
V = l × w × h
Thus:
V = 2.5 × 1.5 × 1 = 3.75 cm³
Convert to fraction:
75/100 = 3/4
Thus, the volume in mixed-numbers is 3 3/4 cm³.
If the math adds up the submarine will travel .6 km in .25 hours.
Plug in 3 for y
8(3)^2-(3)-8
8(9)-3-8
72-3-8 = 61
-13 +3x +8 = 3x + (-5)
-9x + 15 - x -10 = -10 x + 5
The other two don't match
