the value of x if x/80-x = 3/5 is
a. 120
b, 60
c. 30
d. 40
Answer:
The awnser to this is C. 30
Answer:
c
Step-by-step explanation:
We can multiply each side by (80-x) to get:
x = 3/5 · 80 -x
x = 60-x
Move -x to the other side:
2x = 60
Then divide both sides by 2:
x = 30
So, your answer is c. 30

Square Root of 72 in Simplest Radical Form
Simplest Radical Form
Here we answer "What is the square root of 72 (√72) in simplest radical form?" The square root of 72 in its simplest form means to get the number 72 inside the radical √ as low as possible.
Here is how to do that! First we write the square root of 72 like this:
√72
The largest perfect square of the factors of 72 is 36. We can therefore convert √72 like this:
√36 × 2
Next, we separate the numbers inside the √ as such:
√36 × √2
√36 is a perfect square that equals 6. We can therefore put 6 outside the radical and get the final answer to square root of 72 in simplest radical form as follows:
6√2

select the algebraic rule that describes the dialtion of ABC to A'B'C
A.(3x,3y)
B.(2x,2y)
C.(1/3x,1/3y)
Answer: A.(3x,3y)
Step-by-step explanation:
In the given graph,
Triangle A'B'C' is an image of Triangle ABC after dilation.
Algebraic rule for dilation (with center =origin)
[tex](x,y)\to (kx,ky)[/tex] , where k= scale factor.
Coordiantes of A = (1,1) Coordinates of A' = (3,3)
Scale factor = [tex]\dfrac{\text{x-coordinate in image}}{\text{ x-coordinate in pre-image}}[/tex]
[tex]=\dfrac31=3[/tex]
Hence, the required algebraic rule : (3x,3y)
The correct option is A.

Z-m=z+bx , solve for b
Answer:
b= (Z-m-z)/(x)
Step-by-step explanation:
Z-m=z+bx
Z-m-z=bx [Transpose z of R.H.S to L.H.S] / [Substract z from L.H.S and R.H.S]
(Z-m-z)/(x)=b [Divide by x on both sides i.e, L.H.S and R.H.S]
b= (Z-m-z)/(x)
Hope this helps you.

B=m/x

A bicycle has a listed price of 837.95 before tax if the sales tax rate is 7.5% find the total cost of the bicycle with a sales tax include round your answer to the nearest cent as necessary
Answer:
The total cost of a bicycle after the tax = $900.8
Step-by-step explanation:
Given
The cost of a bicycle before tax = 837.95 (let say in $)Sales tax = 7.5% = 0.075To determine
The total cost of the bicycle with a sales tax include
The tax amount can be calculated by multiplying Sales tax i.e. 0.075 with the cost of bicycle before tax i.e. 837.95.
Thus,
Tax amount = 7.5% × 837.95
= 0.075 × 837.95
= $62.85
Thus, the tax amount is: $62.85
Total cost after the tax can be calculated by adding the Tax amount and the cost before tax.
Therefore,
The total cost of a bicycle after the tax = $62.85 + $837.95
= $900.8
Hence, the total cost of a bicycle after the tax = $900.8
Answer:
The total cost of a bicycle after the tax = $900.8

Write the equation of the line that passes through the points (7,3) and (2,-6). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y = (9/5)x - 9.6 in slope intercept (not sure if this counts as reduced?) and y + 6 = 9/5 ( x - 2 ) point slope
Step-by-step explanation:
We need to find the point slope formula. This is y-y1 = m(x-x1). First, we need to find the slope, and we can start to begin to make our equation from there. Slope = rise/run, so 9/5 should be our slope.
y - y1 = 9/5(x - x1) is our new eqn.
Then, we can put one of the points from our line into our eqn, since both pass through our eqn, we can use either point for our calculations.
Sticking with just the first point and substitutuing in values, we get:
y + 6 = 9/5 ( x - 2 ) and now we have to simplify.
y = 9x/5 - 18/5 - 6
y = 9x/5 - (15/5 + 3/5) - 6
y = 9x/5 -3.6-6
y = 9x/5 -9.6
Find the x-and y-intercepts of the graph of 2x - 10y = 36. State your answers as

Step-by-step explanation:
Find the x-intercept:
2x - 10(0) = 36
2x = 36
/2 /2
x=18
(18,0)
Find the y-intercept:
2(0)- 10y = 36
10y=36
/10 /10
y = -18/5 or y = -3.6
(0,-3.6)
