He puts 1/4 of the treasure to aside for himself he gives 1/2 of what is left to his friend bill he shares 2/3 of the remaining

Andrej [43]

Answer:

24 bars of treasure

Step-by-step explanation:

You just need to do the opposite in order to find the total value since you divided the treasure up we need to multiply the treasure “back”.

3 buried bars is equal to 1/3 of the remaining treasure. Multiply by 3 to get 3/3 or 100% of buried and crew portion. So we now have 9 bars. Then multiply by 2 to get 100% of what was given to bill, crew and buried. We now have 18 bars. Then we know that we took 1/4 for ourselves so that means 18 bars represents 3/4 of the treasure. So when we look at factors of 18 we find that 3 x 6 = 18 and 4 x 6 = 24 so we conclude that we had 24 bars of treasure before the split.

Solve for N. <br> 2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]

jonny [76]

Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Step-by-step explanation:

We need to solve the equation $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ and find value of n.

Solving:

$2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$

Multiplying the terms inside the bracket

$2[7-6+6n]+3n=-20+4[6n+6-3n]$

Simplifying:

$2[1+6n]+3n=-20+4[6n-3n+6]$

$2[1+6n]+3n=-20+4[3n+6]$

$2+12n+3n=-20+12n+24$

$2+15n=12n+4$

Adding -12n and -2 on both sides

$15n-12n=4-2$

$3n=2$

$n=\frac{2}{3}$

So, Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Help with num 4 please.

Answer:

y=1/2(x-1)

Step-by-step explanation:

If x=t^2 and t>0, then t=sqrt(x).

If t=sqrt(x) or x^(1/2) and y =1-1/t, then y=1-x^(-1/2).

The x-intercept is when y=0.

So we need to solve 0=1-x^(-1/2) to find point P.

Add x^(-1/2) on both sides: x^(-1/2)=1.

Raise both sides to -2 power: x=1

So point P is (1,0).

Let's find tangent line at point (1,0).

We will need the slope so let's differentiate.

y'=0+1/2x^(-3/2)

y'=1/(2x^(3/2))

The slope at x=1 is y'=1/(2[1]^(3/2))=1/(2×1)=1/2.

Recall point-slope form is y-y1=m(x-x1).

So our line we are looking for is y-0=1/2(x-1)

Let's simplify left hand side y=1/2(x-1)

The depth y (in inches) of a lake after x years is represented by the equation y=0.2x+42 . How much does the depth of the lake i

blagie [28]

Answer:

<h2><em><u> 42.8 in</u></em></h2>

Step-by-step explanation:

Step one:

given data

we are told that the expression for the depth of a lake after x years is given by

$y=0.2x+42$

Required

The value of y when x= 4

Step two:

substitute the value of x in the expression to get y

$y=0.2(4)+42\\\\y=0.8+42\\\\y=42.8\\\\$

<em><u>After 4 years the depth will increase by 42.8 in</u></em>
