Need help with 73, 74, 75, & 76. Find the value of X.
bija089 [108]

Answer:

see explanation

Step-by-step explanation:

73.

18 = 3x\sqrt{3} (divide both sides by 3 )

6 = x\sqrt{3} ( multiply both sides by \sqrt{3} )

6\sqrt{3} = 3x [ \sqrt{3} × \sqrt{3} = 3 ]

divide both sides by 3

x = 2\sqrt{3}

74.

24 = 2x\sqrt{2} ( divide both sides by 2 )

12 = x\sqrt{2} ( multiply both sides by \sqrt{2} )

12\sqrt{2} = 2x ( divide both sides by 2 )

x = 6\sqrt{2}

75.

9\sqrt{2} × x = 18\sqrt{2} ( divide both sides by 9\sqrt{2} )

x = 2

76.

2 = x × \frac{4}{\sqrt{3} } ( multiply both sides by \sqrt{3} )

2\sqrt{3} = 4x ( divide both sides by 4 )

x = \frac{\sqrt{3} }{2}

The sin ratio is the side opposite the reference angle over the hypotenuse.  If Z is our reference angle, then the side opposite it has a length of 32.  The hypotenuse has a length of 40.  Therefore, the sin of Z = 32/40.  We will reduce that to sin Z = 4/5.  First choice above.

3a-4b=12 what does a solve?
leonid [27]

Answer:

a = 4 + -1.333333333b

Step-by-step explanation:

Simplifying

3a + 4b = 12

Solving

3a + 4b = 12

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4b' to each side of the equation.

3a + 4b + -4b = 12 + -4b

Combine like terms: 4b + -4b = 0

3a + 0 = 12 + -4b

3a = 12 + -4b

Divide each side by '3'.

a = 4 + -1.333333333b

Simplifying

a = 4 + -1.333333333b
