3x+8x+4x=6x+63
First, since almost everything is together, combine like terms

15x=6x+63

Now, subtract 6x from both sides

9x=63

Now divide both side by 9

x=7

Now that we have found what x equals, we need to plug in the variable into 5x+23

5(7)+23

Now just simplify

35+23= 58
Therefore, 5x+23 when x=7 is 58

Answer:

z ≈ 145.62

Step-by-step explanation:

using the sine ratio in the right triangle

sin18° = $\frac{opposite}{hypotenuse}$ = $\frac{45}{z}$ ( multiply both sides by z )

z × sin18° = 45 ( divide both sides by sin18° )

z = $\frac{45}{sin18}$ ≈ 145.62 ( to the nearest hundredth )
