"The number of blue markers in a drawer is 4 more than twice the number of red markers."
Elena-2011 [213]

Answer:

b=2r+4

Step-by-step explanation:

I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.

Kenya Kon sells dishwashers. He earns an 8% commission on sales. How much must be sell in order to earn $3000?
Karolina [17]
Use a variable to solve for this.

x * .08 = 3000

Divide by .08 on both sides.
x = 37500

We can check this by inputting 37500 for x.

37500 * .08 = 3000
3000 = 3000

Kenya Kon must earn $37500 to earn $3000.

Calculate the value of x and state the geometric relationship
Allisa [31]
They are same side interior angles and same side interior angles are supplementary (add up to 180 degrees).
So, 6x+12+4x+18=180
Combine like terms:
10x+30=180
Subtract 30 from both sides:
10x=150
Divide both sides by 10:
x=15.

Therefore, the angles are same-side interior angles and x=15.

Alex needs to catch a train. The train arrives randomly some time between and , waits for minutes, and then leaves. If Alex also
8_murik_8 [283]

The probability that the train will be there when Alex arrives is 0.1.

Given that the time that  train arrives between 1:00 P.M to 2:00 P.M. and waits for 10 minutes. Alex arrives between 1:00 P.M to 2:00 P.M.

We are required to find the probability that the train when Alex arrives.

Probability is the likeliness of happening an event among all the events that are possible to happen.

Probability=Number of items/total number of items.

Number of combinations of timings in which the train may have arrived=60/10=6 combinations

Number of ways in which Alex arrives at the station=60.

Probability=6/60

=1/10

=0.1

Hence the probability that the train will be there when Alex arrives ie 0.1.

Question is incomplete. The following things should be included:

Timing in which train arrives is between 1:00 P.M and 2:00 P.M.The train waits for 10 minutes. Alex arrives between 1:00 P.M and 2:00 P.M.
