5/4 or 1 1/4
Solve -2 + 3/4= 1.25
The pyramid formula:

The volume in this case would be:
1/3×7.9×4
=79/30×4
=10.5333...
≈10.5 m^3
Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
