The digit 5 appears twice in the number 255,120. How does the total value of the 5 on the right compare to the total value of th

maksim [4K]

Answer:

The value of the first " $5$ " in the number $255,\!120$ is ten times that of the second " $5\!$ " in this number.

Step-by-step explanation:

What gives the number " $255,\!120$ " its value? Of course, each of its six digits has contributed. However, their significance are not exactly the same. For example, changing the first $\verb!5!$ to $\verb!6!$ would give $2\mathbf{6}5,\!120$ and increase the value of this number by $10,\!000$ . On the other hand, changing the second $\verb!5!\!$ to $\verb!6!\!$ would give $25\mathbf{6},\!120$ , which is an increase of only $1,\!000$ compared to the original number.

The order of these two digits matter because the number " $255,\!120$ " is written using positional notation. In this notation, the position of each digits gives the digit a unique weight. For example, in $255,\!120\!$ :

$\begin{array}{|r||c|c|c|c|c|c|}\cline{1-7}\verb!Digit!& \verb!2! & \verb!5! & \verb!5! & \verb!1! & \verb!2! & \verb!0!\\\cline{1-7}\textsf{Index} & 5 & 4 & 3 & 2 & 1& 0 \\ \cline{1-7} \textsf{Weight} & 10^{5} & 10^{4} & 10^{3} & 10^{2} & 10^{1} & 10^{0}\\\cline{1-7}\end{array}$ .

(Note that the index starts at $0$ from the right-hand side.)

Using these weights, the value $255,\!120$ can be written as the sum:

$\begin{aligned}& 255,\!120\\ &= 2 \times 10^{5} + 5 \times 10^{4} + 5 \times 10^{3} + 1 \times 10^{2} + 2 \times 10^{1} + 0 \times 10^{0} \\&=200,\!000 + 50,\!000 + 5,\!000 + 100 + 20 + 0 \end{aligned}$ .

As seen in this sum, the first " $5$ " contributed $50,\!000$ to the total value, while the second " $5\!$ " contributed only $5,\!000$ .

Hence: The value of the first " $5$ " in the number $255,\!120$ is ten times that of the second " $5\!$ " in this number.

5. -[-2(x-4) - |1-3|] = -2x18

irina [24]

Solving the expression $-[-2(x-4) - |1-3|] = -2x18$ we get value of x: $x=\frac{3}{19}$

Step-by-step explanation:

We need to solve the equation $-[-2(x-4) - |1-3|] = -2x18$ and find value of x

Solving:

$-[-2(x-4) - |1-3|] = -2x18$

Multiply -2 with terms inside the bracket

$-[-2x+8 - |1-3|] = -2x18$

Solving |1-3| we get |-2|=2

$-[-2x+8 - 2] = -2x18$

$-[-2x+6] = -2x18$

Multiply (-) sign with terms inside the bracket

$+2x-6 = -2x18$

Multiply 2x with 18

$2x-6 = -36x$

Add 36x on both sdides

$2x-6+36x =0$

$38x-6 =0$

Add 6 on both sides:

$38x =6$

Divide both sides by 38

$x=\frac{6}{38}$

Simplifying:

$x=\frac{3}{19}$

So, Solving the expression $-[-2(x-4) - |1-3|] = -2x18$ we get value of x: $x=\frac{3}{19}$

charle [14.2K]

Answer:

Jacqueline = 150 minutes

Cassie = 125 minutes

The answer would be 2. (The difference in length between Cassie’s longest and shortest practice sessions was greater than the difference in length between Jacqueline’s longest and shortest sessions.)

Step-by-step explanation: Cassies longest session was 50 minutes. her shortest session was for 15 minutes and they are 45 minutes apart. Jacquelines longest session was 45 minutes and her sgortest was 30 minutes they are onlu 15 minutes away from eachother so the second answer is correct.
