An airplane at 30,100 feet above the ground begins descending at the rate of 2150 feet per minute. Write and solve a linear equa
IrinaVladis [17]

Answer:

30100-2150x and it would take 14 minutes to reach the ground.

Step-by-step explanation:

30100 feet is out starting y coordinate, and since 2150 is always changing depending on the amount of time we multiple it by x (the amount of minutes) therefor we can create the equation 30100-2150x and when we plus in 14 the equation would equal 0

If AC=18x-7,find the x. Round to the nearest hundredth if necessary <br>AB=7x+29 <br>BC=30​
Margaret [11]

Answer:

x=6

Step-by-step explanation:

AC = AB + BC

18x-7=(7x+29)+30

18x-7=7x+29+30

18x-7=7x+59

Add 7 to both sides:

18x-7+7=7x+59+7

18x=7x+66

Subtract 7x from both sides:

11x=66

Divide both sides by 11:

\frac{11x}{11}=\frac{66}{11}

x=6
