Answer:

x = 2

Step-by-step explanation:

3x - 1 = 5

First, add 1 onto both sides. (When doing these type of questions you must do the inverse!)

3x = 6

Divide by 3 on both sides to get x.

x = 2

Hope this helps and I hope you have a good day!

Suppose a ski jumper is 2,650 feet from the base of a ski jump and looks up to the top at an angle of elevation of 26 degrees. A
yuradex [85]
We can draw a right triangle to easily visualize the given problem. Since the ski jumper is 2650 ft from the base of the ski jump, we can consider this as one of the right triangle's legs. 

What we're looking for is the height of the ski jump or the other leg of the right triangle. Since the ski jumper looks up at an angle of elevation of 26°, we can use the tangent function to find the missing height. You may refer to the image below to better understand the problem. 

Recall that tanθ = (opposite side facing the angle)/(side adjacent to the angle). For this case, we have

\tan26= \frac{x}{2650}\\2650(\tan26) = x\\x \approx1292.49

Hence, the height of the ski jump (rounded off the nearest whole foot) is 1292 feet. 

Answer: 1292 feet

9 more than the product of 51and a number t. please show work
LekaFEV [45]
To find out the answer to this question, you need to represent the equation as follows: the product of 51 and t can be represented as 51*t, or 51 multiplied by t. The answer is 51t, so 9 more than that will be 51t+9.

Yep here we go again, me freaking out
Kryger [21]

Answer:

78

Step-by-step explanation:

You know that each minute represents 6 degrees of a difference because there are 360 degrees total and 60 minutes, so 360/60 = 6 degrees.

13 minutes passed, so 13 * 6 = 78 degrees
