Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

2(5x+2)^2=48

If we divide it from 2 in both sides

\frac{2(5x+2)^2}{2}=\frac{48}{2}

(5x+2)^2=24

Taking square root on both sides

(5x+2)=±24

(5x+2)=±2√6

Subtracting 2 in both sides

5x=±2√6-2

Dividing 5 in both sides

x=\frac{2\sqrt{6}-2 }{5} or x=\frac{-2\sqrt{6}-2}{5}  :  Answer

Hope it will help :)

The diagram shows the diffrence between my home h and two towns
katrin2010 [14]

Answer:

  • from home to town A :

V = D/t = 10 / 20 = 0.5 mile per min

  • from home to town B :

V = D/t = 20/30 = (2/3) mile per min

  • From town A to town B :

V = D/t = (10+20)/ 50 = (3/5) mile per min

Find the value of x such that 365 based seven + 43 based x = 217 based 10.
Pepsi [2]

We need to find the base x in the following equation:

365_7+43_x=217_{10}

First, lets convert 365 from base 7 to base 10. This is given by

365_7=3\times7^2+6\times7^1+5\times7^0

where the upperindex denotes the position of eah number. This gives

\begin{gathered} 365_7=3\times49+6\times7+5\times1 \\ 365_7=147+42+5 \\ 365_7=194_{10} \end{gathered}

that is, 365 based 7 is equal to 194 bases 10.

Now, lets do the same for 43 based x. Lets convert 43 based x to base 10:

43_x=4\times x^1+3\times x^0

where again, the superindex 0 and 1 denote the position 0 and 1 in the number 43. This gives

43_x=(4x+3)_{10}

Now, we have all number in base 10. Then, our first equation can be written in base 10 as

194_{10}+(4x+3)_{10}=217_{10}

For simplicity, we can omit the 10 and get

194+4x+3=217

so, we can solve this equation for x. By combining similar terms. we have

197+4x=217

and by moving 197 to the right hand side, we obtain

\begin{gathered} 4x=217-197 \\ 4x=20 \end{gathered}

Finally, we get

\begin{gathered} x=\frac{20}{4} \\ x=5 \end{gathered}

Therefore, the solution is x=5

David is right times older than Nicole. If David is 32 years old , how old is Nicole? Write an equation to solve Nicole's age.
rosijanka [135]

Answer:

8a=32

Step by Step

Since David is 8x older than Nicole you could write Nicole as the age of a, so then David would be 8a. You are given David is 32 years old so you set 8a equal to 32.

Answer is 4

Nicole is 4 years old

8a=32

divide both sides by 8

Answer is 4
