Answer:
x= 4
Step-by-step explanation:
2x + 3( 5x - 7) = 47
2x + 15x - 21 = 47
17x -21 = 47
17x = 47 + 21
17x = 68
x = 68 / 17
x = 4

<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.
Let l represent the length of the string, hence:
sin(28) = l / 75
l = 159.75 feet < 162 feet

Pretty sure it is y=2x+1 because of y=mx+b
Rate times time equal distance
75*t=30
Divide both sides by 75.
