<h3>1)</h3>

x = y + 5 \\ y = x - 5

<h3>2)</h3>

x =  \frac{3}{8} y \\ y =  \frac{8}{3}x

<h3> 3)</h3>

x =  - y - 2 \\ y =  - 2 - x

<h3>4)</h3>

x = 6y + 1 \\ 6y = x - 1 \\ y =  \frac{x - 1}{6}

<h3>5)</h3>

x = y - 11 \\ y = x + 11

<h3>6)</h3>

x = 8y \\ y =  \frac{x}{8}

<h3>7)</h3>

x =  \frac{ - 1}{3} y \\ y =  - 3x

basically \: flip \: x \: and \: y \: then \: solve \: for \: y

A cell phone package charges $39 even if 0 minutes are used during the month. Each additional minute of talk time adds $0.07. Wh
zmey [24]

Answer:

total cost = $ 81

Step-by-step explanation:

It is given that the fixed cost is $ 39

and the cost per minute is $0.07

Let us assume the number of minutes used be x

we have

total cost = cost per minute × number of minutes used  + fixed cost

we plug the given values, so we have

total cost = 0.07 x+39

we need to find the total cost for 10 hours used

x= 10 hours = 10(60) minutes = 600 minutes

so we have total cost for x= 600 minutes

total cost = 0.07(600)+39

total cost =42+39 = 81

hence the total cost = $ 81

Can someone help me solve this? ​
AysviL [449]

1.8

to find the circumference of a circle you have to multiple the diameter by pi (3.14). so if you have the circumference already just switch around the equation (since you don’t know the diameter) to 10.99 divided by 3.14 to find the diameter and you get 3.5. but thats the diameter and you have to find the radius so divide 3.5 by two and you get 1.75 and 1.75 rounded to the nearest tenths is 1.8
