1) \frac{5}{4}= \frac{25}{y} 

5y=100
y=20

2) \frac{x}{0.6} =  \frac{9}{0.5}
\frac{10x}{6} =  \frac{90}{5}
50x=540
x=10.8

3) 2x=12
x=6

4) x-7+x
2x-7

5) x-x+4=4

If you need explanation just ask.

Find the ranges giving brainlest
scoray [572]

Answer:

The range for Problem 18 is

16.1

The range for problem 19 is

167

Step-by-step explanation:

To find the range you subtract the smallest value from the largest value. In problem 18 the largest value was 17.6 and the smallest was 1.5.

17.6 - 1.5 = 16.1

In problem 19 the largest value was 181 and the smallest was 14

181 - 14 = 167

If –y + 2x^2 – x = -5y^3 then find dy / dx in terms of x and y.
vlada-n [284]

Answer:

dy/dx = \frac{4x-1}{1-15y^{2} }

Step-by-step explanation:

-y + 2x²- x = -5y³

2x² - x = y - 5y³

4x - 1 = dy/dx - 15y².dy/dx

dy/dx(1 - 15y²) = 4x - 1

dy/dx = \frac{4x-1}{1-15y^{2} }

a tea company surveyed shoppers at two different malls. shoppers were asked whether they prefer sweetened or unsweetened tea. at
FromTheMoon [43]
First, let's create the ratios of sweetened to unsweetened. To do this, you would have to subtract the number of people that preferred unsweetened from the total.
Westside mall: 15:30 or \frac{15}{30}
Eastside mall: 13:26 or \frac{13}{26}

Now, you would divide to both ratios.
15 ÷ 30 = 0.5
13 ÷ 26 = 0.5 

They have the same sum, meaning, they are the same. 

Westside Mall shoppers are just as likely to prefer unsweetened tea as Eastside Mall shoppers. 

I hope this helps!
