Answer:
Option (1)
Step-by-step explanation:



System of equations can be written as,


Therefore, system of equations given in Option (1) is the correct option.
2a. speed= distance
---------------
time
60÷69 = 52.1739 miles per hour.
so for the next one with the airplane flies 296 km in 276 min is the same formula.
296/276 = 39.9839 mph.
I couldn't see the first question clear...sorry but apply same formula.
Hoping this will help you
To write this in standard form, you need to eliminate the
fraction in the coefficient of variable x. You can do this by multiplying 8 to
the two sides of the equation:
8(y) = 8[(-5/8)x + 3]
8y = -5x + 24
Transpose the variable x to the other side:
5x + 8y = 24
Hey there Gary!
If Angle DBC is 73, you do subtract it from 180 to get ABD.
180 - 73 = 107
Angle ABD = 107
Angle DBC = 73
Angle ABD > DBC
or
Angle DBC < ABD
The line BD/DB is the same length in both angles, proving line AD is greater than CD. This is also justified by the fact that lines AB and CB are congruent.
I hope this helps, let me know if there's something wrong about my answer.
