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 AB=7x+29 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:

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

$x=6$

Determine if each pair or ratio or rate is equivalent. 16 out of 28 and 240 of 560

Keith_Richards [23]

Those ratios are not equivalent because 240 divided by 16 is 15 and 560 divided by 28 is 20.
