We know that there are 4 kings in the deck. 
From this we know that there are 2 black suits. 

Hence, 2/4 = 1/2 = 50%. 
Thus, the odds are 50% in drawing a black suited King.

Nicole rented a bike from Krystal's Bikes. It costs $15 plus $7 per hour. If Nicole paid $43, then she rented the bike for how m
murzikaleks [220]

Given that Nicole rented a bike from Krystal's Bikes, the number of hours is

4 hours

Given data

Initial Cost  = $15

Cost per extra hours = $7

Amount Paid = $43

The Expression that we will use to describe this situation is modelled below

let y = Amount paid

    m = cost per extra hour

    x = the number of hours

   c = the initial cost

y = mx + c -------- Equation of line

43 = 7*x + 15

43 = 7x+15

7x = 43-15

7x = 28

divide both sides by 7

x= 28/7

x= 4 hours

Hence the number of hours is 4 hours

What is the least number you could multiply by to write an equivalent equation with integer coefficients?
Helga [31]
The least common multiple of the divisors 3 and 2 is 6. Multiplying by 6 gives you
  2(4a+1) = 3a

Multiply both sides of the equation by 6.

Find the value of x. Your answer must be exact.<br> х<br> 45° 18
ludmilkaskok [199]

Answer:

x = 63

Step-by-step explanation:

Simplifying

x + -18 = 45

Reorder the terms:

-18 + x = 45

Solving

-18 + x = 45

Solving for variable 'x'.

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

Add '18' to each side of the equation.

-18 + 18 + x = 45 + 18

Combine like terms: -18 + 18 = 0

0 + x = 45 + 18

x = 45 + 18

Combine like terms: 45 + 18 = 63

x = 63

Simplifying

x = 63

Cities A &amp; B are 5 inches apart on a map. Cities Ce Dare 4 inches apart. If C &amp; D are 900 miles apart how many miles apa
Afina-wow [57]

Answer:

<u>Cities A and B are 1,125 miles apart</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Distance between A and B in the map = 5 inches

Distance between C and D in the map = 4 inches

Real distance between C and D = 900 miles

2. How many miles apart are cities A and B?

We will solve the question, using Direct Rule of Three, as follows:

Distance in the map      Real distance

A - B     5 inches                    x

C - D     4 inches                900 miles

***************************************************

4x = 900 * 5

4x = 4,500

x = 4,500/4

x = 1,125 miles

<u>Cities A and B are 1,125 miles apart</u>
