a car can travel 476 miles on 14 gallons of gas. Write an equation relating the distance d to the number of gallon g. How many g
ch4aika [34]

miles per gallon (x) = d/g

x = 476/14 = x = 34 miles per gallon

so d/x = g

578/34 = 17 gallons are needed

2(x+4)/3 =12<br><br> What is da answearrrrrr
dem82 [27]

Answer:

x = 14

Step-by-step explanation:

Given

\frac{2(x+4)}{3} = 12

Multiply both sides by 3 to clear the fraction

2(x + 4) = 36 ( divide both sides by 2 )

x + 4 = 18 ( subtract 4 from both sides )

x = 14

While surveying Overlook Cave, Mike measures the angle of elevation from his line of sight to the top of a rock formation as 22°
Kaylis [27]

Answer:

The rock formation is approximately 7 feet tall.

Step-by-step explanation:

<em>We can visualize this situation as a triangle and know that the bottom side is </em><em>10</em><em> and the angle of elevation (the angle created by Mike and the ground, looking to the top of a rock). With this information, we can use tangent to solve.</em>

<em>x = the height of the rock formation</em>

tan(22°) = x/10

10 tan(22°) = x

x = ~4.04 feet

<em>We also have to add the </em><em>3 feet</em><em> to it because it is being measured 3 feet above the floor.</em>

x + 3 = 7.04 feet
