Answer:

∠ DBC = 16°

Step-by-step explanation:

∠ ABD + ∠ DBC = ∠ ABC , substitute values

2x + 15 + x - 30 = 123 , that is

3x - 15 = 123 ( add 15 to both sides )

3x = 138 ( divide both sides by 3 )

x = 46

Thus

∠ DBC = x - 30 = 46 - 30 = 16°

A bike store sells scooters at a 54% markup. If the store bought each scooter for $29.25, what is the resale price to the neares

7nadin3 [17]

The purchasing price of the store = $29.25.

They want to resale it at 54% markup of the purchasing price.

54% of 29.25 = 0.54 × 29.25.

On multiplying 0.54 and 29.25, we get 15.795.

Resale price = The purchasing price + Markup

= 29.25 + 15.795.

On adding 29.25 and 15.795, we get 45.045.

We can round it to 45 to the nearest dollar.

<h3>Therefore, the resale price to the nearest dollar is $45.</h3>

If G is the midpoint of FH find FG<br>fg=11x-7 gh= 3x+9

gavmur [86]

Solution:

we are given that

If G is the midpoint of FH, it mean that

$FG=GH$

we are also given that

$FG=11x-7 ,GH= 3x+9$

So we can write

$11x-7=3x+9\\
\\
11x-3x=7+9\\
\\
8x=16\\
\\
x=2$

So $FG=11x-7=11*\frac{1}{2}-7=11*2-7=15$
