Answer: he is 16

Step-by-step explanation:

Let x = Frank's age

2x+4+ = Charlie's age

x+3+ = Bob's age

9 = Bob's age

x+3=9

x=6

2x+4=2⋅6+4

2x+4=12+4

2x+4=16

Charlie is 16

a court reporter is transcribing an accident report the report states that the driver was traviling 110km per hour how many mile

Vera_Pavlovna [14]

Answer:

The driver was traveling at approximately 68.2 miles per hour

Step-by-step explanation:

Recall that one km equals approximately 0.62 miles, therefore, in order to find the speed of the driver in miles per hour, we just need to convert the 110 km into miles.

if one km equals 0.62 miles, then 110 km will equal the product of 110 times 0.62 miles. That is:

110 * 0.62 = 68.2 miles

Then the speed will translate into :

110 km/h = 68.2 mi/h

Given z^3 = 3 + square root 3i which letter represents z

Marianna [84]

The expression that represents the value of z is $\sqrt[3]{3 + i\sqrt 3 }$

<h3>What are complex numbers?</h3>

Complex numbers are numbers that have real and imaginary parts

A complex number (n) is represented as:

$n = a + bi$

From the above expression, we have:

a represents the real part
bi represents the imaginary part

Given that:

$z^3 = 3 + \sqrt 3 i$

Rewrite the above expression as:

$z^3 = 3 + i\sqrt 3$

Take the cube roots of both sides

$z = \sqrt[3]{3 + i\sqrt 3 }$

The letters are not given.

Hence, the expression that represents the value of z is $\sqrt[3]{3 + i\sqrt 3 }$

y=15(25)+200

y=575

Rose-

500 a week (25 hour week) so 20 an hour in the m space

nothing plugged into the b space because there is no extra cash to be added

25 hours of work gets plugged into the x

y=20(25)+0

y=500

Poppy-

30 an hour plugged into the m spot

nothing plugged into the b space because there is no extra cash to be added

25 hours of work gets plugged into the x

y=30(25)+0

y=750

Daisy-

350 for getting the job goes to the b space

12.50 an hour plugged into the m spot

25 hours a week gets plugged into the x

y=12.50(25)+350

y=662.5

Violet-

450 for getting the job gets placed into the b spot

6 an hour plugged into the m space

25 hours a week gets plugged into the x

y=6(25)+450

y=600

Hope this helps!
