Adding the tax?
 
to add taxes it requires only two steps:
1) multiply the price by the tax as a Decimal (tax must be in decimal form)
2) add what you get after multiplying to the original price
 So..
1) 49.95(.05) = 2.497
 
2) 49.95+ 2.497 = 52.447 round to 52.45

So the whole price is $52.45

**you can also round the 49.95 to 50 before doing the math to make it easier**

At a temperature of t degrees​ Fahrenheit, sound travels s feet per​ second, where s equals 21.9 StartRoot 5 t plus 2457 EndRoot
mafiozo [28]

Answer:

32.63 F

Step-by-step explanation:

The function:

s = 21.9 \; \sqrt{ 5 t + 2457 }

represents sound travels s at feet per​ second, where t is the temperature at Fahrenheit degrees​.

We know that sound traveled at a rate of 1121 ​ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.

1121 = 21.9 \; \sqrt{ 5 t + 2457 }

\frac{1121}{21.9} = \sqrt{ 5 t + 2457 }

51.19^2 = 5 t + 2457

2620.13 - 2457 = 5 t

\frac{163.13}{5} = t

32.63 \; F= t

The figure below is a parallelogram. Find the measure of the<br> variables.
Ilya [14]

Answer:

B.

Step-by-step explanation:

Since 6 = 5r + 1, r = 1

As for s, if s is 2, then you can do

4 x 2 + 5 = 13 & 6 x 2 + 1 = 13

13 = 13

So B!

Hope that helps!

If 4x+y= x solve for x.
erik [133]

4x+y= x

Move all x term to left side

4x-x+y=0

Subtract 4x from 3x

3x+y=0

Move y term to right side

3x= -y

Divide both sides by 3

X= -y/3



Ok so if it's


4x+y= z solve for x


Move y to right side


4x= -y +z


Now divide both by 4 to get x alone


X= -y/4 + z/4
