If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
10 + 3(5n - 12) = 13n
10 + 15n - 36 = 13n
15n - 13n = 36 - 10
2n = 26
n = 13 [Answer C]
Answer:
3 and 4
Step-by-step explanation:
proportionally it is the same shape and 2/1 is 2 so that's your scale factor
Answer:
x = 20
KPL = 64
JPL = 116
Step-by-step explanation:
A linear pair adds to 180 degrees
2x+24 + 4x+ 36 = 180
Combine like terms
6x+60 = 180
Subtract 60 from each side
6x = 120
Divide by 6
6x/6 = 120/6
x = 20
KPL = 2x+24 = 2*20+24 = 40+24 = 64
JPL = 4x+36 = 4*20 +36 = 80+36 = 116
20 percent off of 80 should be 16. So 80-16 = 64.
She paid $64 for a $80 pair of shoes.
(Side note- $80 for shoes is a lot!)
She saved $16
