Answer:
4$
Step-by-step explanation:
The ratio between the $5.80 spent for 58 text messages is $0.10. This means that each text message sent is $0.10. So you just multiply $0.10 and 40 text messages to find that it costs $4 to send 40 messages.
ANSWER:
As we know, diagonals of parallelogram (||gm) bisect each other.
So, AE = EC
2x - 10 = 8x - 70
2x - 8x = - 70 + 10
- 6x = - 60
x = 10
The plane went 100 meters higher than its original height
Answer:
30°
Step-by-step explanation:
Angle C = 55°, Angle D = Angle A = 65°, Angle B = 2x
Sum of angles in a triangle = 180°
65° + 55° + 2x = 180
120 + 2x = 180
2x = 180 - 120
2x = 60
x = 30°
Answer:
$828
Step-by-step explanation:
15% = 0.15
0.15 x 720 = 108
total cost = $720 + $108 = $828
