40 meters in 60 seconds could be expressed as

So, in order to get the unit rate, we divide the numerator and denominator by 16.

So, the unit rate is 2.5 meters per second (or every one second)
7. Alternate interior
8. Congruent
9. Work:
6x - 16 = 2x + 40
4x = 56
x = 14
Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer:
The surface area is 270in units squared
