- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-5x + 6y = 55
4x + 3y = 34
<u>Step 2: Rewrite Systems</u>
4x + 3y = 34
- Multiply everything by -2: -8x - 6y = -68
<u>Step 3: Redefine Systems</u>
-5x + 6y = 55
-8x - 6y = -68
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -13x = -13
- Divide -13 on both sides: x = 1
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 4x + 3y = 34
- Substitute in <em>x</em>: 4(1) + 3y = 34
- Multiply: 4 + 3y = 34
- Isolate <em>y</em> term: 3y = 30
- Isolate <em>y</em>: y = 10
Answer:
A
Step-by-step explanation:
Ratio of volume is ratio of the radius raised to the power 3.
8*10 squared as a decimal would be 2.8
Do u mean 9.375? if that is the case it would be
9.38
Answer:
6p + 8b
Step-by-step explanation:
Let us assume that p would be the number of cups in each pack
And b would be the number of cups in boxes
Given that
There are 6 cups in each pack
And, 8 cups in each box
So the totla number of cups in each pack be 6p
And, the total number of cups in each box is 8b
Now the total number of cups did Alision buys is 6p + 8b
