Answer:
Divide both sides by-2
Use the distributive property
Step-by-step explanation:
If you divided both sides by -2, you would get n + 3 = -6.5. Then you would have to subtract 3 from both sides, so n would be -9.5.
However, if you used the distributive property, you would get -2n - 6 = 13. Then you could add 6 to both sides and get -2n = 19. Finally, to solve for n, you would divide both sides by -2 to get n = -9.5.
Hope this helps!
Answer:
- The radius of the container is approximately 4.89 cm
Step-by-step explanation:
<h3>
Given </h3>
A container with:
<h3>
To find</h3>
- The radius of the container
<h3>Solution</h3>
Use the equation for total surface area of cylinder:
- S = 2πr² + 2πrh or S = 2πr(r + h)
Since we have r = h and the value of S is known, let's solve this equation:
- 2πr(r + h) = 300
- 2πr(r + r) = 300
- 2πr(2r) = 300
- 4πr² = 300
- πr² = 75
- 3.14r² = 75
- r² = 75/3.14
- r² = 23.89 (rounded)
- r = √23.89
- r = 4.89 cm (rounded)
Answer:
Option 3 - 4/3
Step-by-step explanation:
When solving equations, we use inverse operations. The inverse of 3/4 is the reciprocal 4/3. Option 3 is the solution.
Answer:
48.14= $58.25
$97.92= 81.27 euro
Step-by-step explanation:
Giving the following information:
1 Euro is currently valued at 1.21 U.S. Dollars.
<u>First, we need to calculate the dollar value of 48.14 euros.</u>
Proportion equation used for answer below: 1e= 1.21d
48.14*1.21= $58.25
<u>Now, the euro value of 97.72 dollars.</u>
Proportion equation used for answer below: (1:1.21) 0.83
1 dollar equals 0.83 euro.
97.92*0.83= 81.27 euro
