The sum of three numbers is 75. the second number is 5 more than 4 times the first, and the third is 2 times the first. find the second number.

Second number = 4(10) + 5 = 45

Step-by-step explanation:

First number = x

Second number = 4x + 5

Third number = 2x

Therefore, the total is:

x + (4x + 5) + 2x = 75

Combine like terms:

7x + 5 = 75

Subtract 5 from both sides:

7x = 70

Divide both sides by 7:

x = 10

Recall that x represents the first number. Therefore, the first number is 10. The second number is 4(10) + 5 = 45. The third number is 2(10) = 20. To verify: 10 + 45 + 20 = 75. Check.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
