Answer:

If solving for x then x = -3/2 +y/2

If solving for y then y = -3-2x

Step-by-step explanation:

For x: Divide both sides by 2

For y: Subtract 2x from both sides of the equation

Answer:

A

Step-by-step explanation:

To know the distance between the two on a number line, we subtract both numbers from each other

Since the absolute value will give the same result irrespective of the number we used first, we can see that it is the first option that would give the needed results

This means that option A is our answer

The sunrise café gets tea bags of 1,000. If the café charges $1.75 for each cup of tea, and each cup of tea gets 1 tea bag, how
Setler [38]

Answer:

You would do $1.75 x 1,000. That would be 1$,750. Then, you would take away that $95 because they spent buying the box of tea bags, and their total would be $1,750 - $95 = $1,655.

triangle QRS is an equilateral triangle. If QR is seventeen more than twice x, RS is 19 less than six times x, and QS is one les
koban [17]

Value of x is 9 and measure of each side is 35 units.

<u>SOLUTION: </u>

Given, Triangle QRS is an equilateral triangle.  

QR is seventeen more than twice x, \rightarrow QR = 17 + 2x

RS is 19 less than six times x, \rightarrow RS = 6x-19

And QS is one less four times x, \rightarrow QS = 4x-1

We have to find x and measure of each side.

Now, we know that, sides of equilateral triangle are equal,  

Then QR = QS \rightarrow 17 + 2x = 4x-1 \rightarrow 4x-2x = 17 + 1 \rightarrow 2x = 18 \rightarrow x = 9

So, value of x is 9.

\begin{array}{l}{\text { Now, } \mathrm{QR}=17+2(9)=17+18=35} \\\\ {\mathrm{RS}=6(9)-19=54-19=35} \\\\ {\mathrm{QS}=4(9)-1=36-1=35}\end{array}

Hence, value of x is 9 and measure of each side is 35.

I need help with this problem! Thank you!
QveST [7]

Answer:

<em>The amount of water in the reservoir at the beginning of second week</em>

<em></em>w_{2} = 299.8800<em></em>

Step-by-step explanation:

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

<em>Given equation </em>

<em>   w₀ = 300  and </em>

w_{n} = (0.9993) w _{n-1} + 0.15

Put n =1

w_{1} = (0.9993) w _{1-1} + 0.15

w_{1} = (0.9993) w _{0} + 0.15

w_{1} = (0.9993) X 300 + 0.15

w_{1} = 299.94

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

<em>Put n =2</em>

w_{2} = (0.9993) w _{2-1} + 0.15

w_{2} = (0.9993) w _{1} + 0.15

w_{2} = (0.9993) X (299.94) + 0.15

w_{2} = 299.8800

<u><em>Conclusion:</em></u>-

<em>The amount of water in the reservoir at the beginning of second week</em>

<em></em>w_{2} = 299.8800<em></em>

<em></em>

let length of the rectangle be l

length is 6 cm longer than the width, w

l = w + 6

 perimeter of rectangle is 72 cm

= 2l + 2w

substitute l = w + 6

2(w+6) + 2w = 72

4w + 12 = 72

4w = 60

x = 15

ans is C. 15 cm
