zhenek [66]3 years ago

Answer:

a) x =18

b) x=2

c) x=3

Step-by-step explanation:

<u><em>Step(i):-</em></u>

a)

Given that (x-2)^{\frac{1}{4}  }

     put x = 18

   ⇒    (18-2)^{\frac{1}{4} } = (2^{4} )^{\frac{1}{4} } = 2

      (x-2)^{\frac{1}{4}  } =2    

b)

put x= 2

(1-x)^{\frac{1}{3}  } =  (1-2)^{\frac{1}{3}  } = (-1)^{\frac{1}{3} } = -1

 (1-x)^{\frac{1}{3}  } = -1

c)

put x=3

\sqrt{x^{2} +7} = \sqrt{3^{2} +7} = \sqrt{16} = 4

\sqrt{x^{2} +7}= 4

If ba-cd =b which expression represents "a"?A. b-cd/bB. b+cd/bC. b/b-cdD. b/b+cd
navik [9.2K]

Isolating the variable 'a' in the expression, we have:

\begin{gathered} ba-cd=b \\ ba=b+cd \\ a=\frac{b+cd}{b} \end{gathered}

So the correct option is B.

A cash box of $1 and $5 bills is worth $45. The number of $1 bills is three more than the number of $5 bills. How many of each b
Softa [21]

Answer:

  • 7 $5 bills
  • 10 $1 bills

Step-by-step explanation:

If we take out the extra $3, we can group the bills into one each of $5 and $1, for a value of $6. There will be 7 such groups in the remaining $42.

That means there are 7 bills of the $5 denomination, and 3 more than that (10 bills) of the $1 denomination.

There are 7 $5 bills and 10 $1 bills.

_____

If you want to write an equation, it is usually best to let a variable stand for the most-valuable contributor. Here, we can let x represent then number of $5 bills. Then the value of the cash box is ...

  5x +(x+3) = 45

  6x = 42 . . . . . . . . subtract 3, collect terms

  x = 7 . . . . . . . . . . . there are 7 $5 bills

  x+3 = 10 . . . . . . . . there are 10 $1 bills

You may notice that this working parallels the verbal description above. (After we subtract $3, x is the number of $6 groups.)

Solve the equation.<br> -5=x+3<br> Ox=3<br> Ox=-3<br> Ox=8<br> Ox=-8
weqwewe [10]
Answer:
x= -8

Explain:
You first have to make the variable by itself so you subtract 3 on both sides. The x is by itself and you finish by subtracting -5 to 3 and you get the answer x = -8

Hope this helps

Sue spent 1 hour 19 minutes less than Jared reading last week. Jared spent 45 minutes less than Pete. Pete spent 3 hours reading
polet [3.4K]

Sue spend 56 minutes in reading.

<h3>What is Unitary Method?</h3>

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Sue spent 1 hour 19 minutes less than Jared

Lucas spent 45 minutes less than Pete.

Pete spent 3 hours reading.

Since, pete spent 3 hours. So, Jared spent

= 3 hours or (180 minutes) - 45 minutes

= 2 hours 15 minutes.

Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes  

                           = 56 minutes
