- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
The answer is A. 9, 12, 15,
Answer:
0
Step-by-step explanation:
-2 minus -2 = 0
9 minus -5 = 14
0 divided by 14 = 0
Answer:
Step-by-step explanation:
step 1
Find the volume of the prism
The volume of the prism is equal to
we have
substitute
step 2
Find the volume of the pyramid
The volume of the pyramid is
where
B is the area of the base
---> half the height of the prism
substitute
step 3
we know that
The volume of the space outside the pyramid but inside the prism is equal to subtract the volume of the pyramid from the volume of the cylinder
