- 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:
1. x^8
2. x^8
3. 1024
4. -21a^4
5. z^10
6. -9x^7
7. 42r^7
8. b^7
9. 8a^11
10. 12p^12
Step-by-step explanation:
Vcylinder=hpir^2
VA=hpi6^2
VB=hpi(6/2)^2=hpi3^2
A times ?=B
?= a fraction
hpi6^2 times ?=hpi3^2
divide both sides by hpi
6^2 times ?=3^2
36 times ?=9
divide both sides by 36
?=9/36
?=1/4
1/4 of A is B
12/6 you have to put it on top and bottom then subtract
Answer:
8 cubes
Step-by-step explanation:
1^3=1
(1/2)^3=1/8
1/(1/8)=1*8=8
