Answer:

  • See below

Step-by-step explanation:

  • 1. c increased by 5 is 5                       ⇒ h. c + 5 = 5
  • 2. 4 more than a number is 12           ⇒ b. n + 4 = 12
  • 3. The product of 4 and n is 12          ⇒ i. 4n = 12
  • 4. The difference of 27 and k is 15    ⇒ a. 27 - k = 15
  • 5. 8 less than 3 times x is 10              ⇒ f. 3x - 8 = 10
  • 6. 3 times x increased by 8 is 20      ⇒ d. 3x + 8 = 20
  • 7. A number minus 8 is 3                   ⇒ e. k - 8 = 3
  • 8. Three times a number is 9            ⇒ j. 3n = 9​
  • 9. Twice a number plus 1 is 11           ⇒ g. 2x + 1 = 11
  • 10. 6 less than a number is 5            ⇒ c. c - 6 = 15

Solve this equation. <br> Leave the answer as an improper fraction. <br> 3x^2 + 2 = 11 - x^2
Nikolay [14]

Answer:

x = \frac{3}{2}orx=-\frac{3}{2}

Step-by-step explanation:

The given Equation is

3x^{2} + 2 = 11-x^{2}   .................(i)

Adding ( x^{2} -11 ) on both sides of  (i)

3x^{2}+2+x^{2}-11 = 11-x^{2}+x^{2}-11

solving and cancelling out the terms will give

⇒ 4x^{2} -9=0  

⇒ (2x)^{2} -(3)^{2} = 0     ...................(ii)

Now we Know that

(a)^{2} -(b)^{2} = (a-b)(a+b)  

Applying this on equation (ii)

(2x-3)(2x+3)=0

This will lead us to

Either 2x-3 =0    .......(iii)        or     2x+3=0   ..........(iv)

Solving equation (iii) for value of x

2x - 3 =0

adding 3 on both sides

2x -3 +3 = 0+ 3

2x = 3

Cross multiplying gives

x=\frac{3}{2}

Solving equation (iv) for value of x

2x + 3 =0

adding -3 on both sides

2x -3 +3 = 0- 3

2x = -3

Cross multiplying gives

x=\frac{-3}{2}

so x=\frac{3}{2} and x=\frac{-3}{2}

Round 8.95 to the nearest tenth.did the ones place change? explain
Gekata [30.6K]
8.95 to the nearest tenth.

The tenth digit is the first after the decimal point to the right. And that is 9.
Looking at the next digit after it is 5, and it is up to 5 so we increase the 9 to 10.

And of course the 10 would cause an increase to the 8 for it to become 9.

≈ 9.0  to the nearest tenth.
