Answer:
20 feet
Step-by-step explanation:
1st piece = x
2nd piece = 2x
3rd piece = 6x
x+2x+6x=180
9x=180
x=20
so the first piece is 20 feet, the second is 40, and the third is 120.
Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"
Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p
480p + 260p + 16 = 740p + 16
740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p stands for though. If it is cents, divide 100 from 740 and take out the p, then add total to 16 to get answer.)
hope this helps

Answer below Please give brainliest!!
Step-by-step explanation:
Sue Black: 8x5=40 hours 40 x $6.75 = $270
Jerry Atrix: 7.25 + 3 + 6.75 + 8 + 5 = 30 hours
30 x $5.15 = $154.50
Sam Ting: 7.75 x 5 = 38.75 hours
38.75 x $8.75 = 339.0625 = $339.06
$600x06x3= $108.00- the interest and with the $600 it would be $708
<< Add
to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.
A)
25x.(-32)= (-16).5
-800x= -80
**to leave x alone and positive, you must divide to -800.
= INCORRECT
B)
C)
10x=1
D)
40x= 4
x=
= 1/10
I think there is a problem with the options :D
