What value of n makes the equation 2(0.5n − 3) = n − 0.25(12 − 12n) true?

Answers

Answer 1

Answer:

-1

Step-by-step explanation:

2(.5n-3)=n-0.25(12-12n)

first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis

1n-6=n-3+3n

then you combine like terms and end up with

1n-6=-3+4n

add 6 to each side to get

n=3+4n

subtract 4n from each side to get

-3n=3

divide -3 from each side to get

n=-1

A jar contains 30 red marbles, 50 blue marbles, and 20 white marbles. You choose one marble from the jar at random. What is the theoretical probability of choosing a red marble?

Answers

The total number of marbles is 30+20+50= 100, so. Since there are 20 red marbles and 50 blue marbles. There are 30+50=80. 80/100=4/5= 80%

Answer:

30%

30+50+20=100, and since there's 30 red marbles, you have a 30% chance of picking a red out of the 100 marbles.

Rick is buying $115 tennis racket from a sporting good store. If the racket is on sale for 35% off in sales tax is 8% how much will he pay in total

Answers

Answer:

$80.73

Step-by-step explanation:

First, find 35% of 115.

35% as a decimal is 0.35 (35/100)

0.35 x 115 = 40.25

Now, subtract 40.25 from 115.

115 - 40.25 = 74.75

Now, to find the sales tax, find 8% of 74.75.

8% as a decimal is 0.08 (8/100)

0.08 x 74.75 = 5.98

Now, subtract add 5.98 to 74.75

5.98 + 74.75 = 80.73

Yesterday, Ian walked 2/3 of a mile. Today, he walked 1/5 of a mile. How far did he walk altogether?

Answers

Answer:

1.4km

Step-by-step explanation:

2/3 + 1/5

Find the LCM of the denominators

(5x2)+(3x1)/15

Clear brackets:

5x2=10

3×1=3

Therefore, we have

10+3/15=13/15

In total, he has walked 13/15 of a mile

1 mile is 1.609344 km

Therfore, he walked 13/15×1.609344 km=1.4km approximately.

OR

2/3 of 1mile is 2/3×1.609344 km

=1.07km

1/5 of 1 mile the next day is 1/5×1.609344 km

=0.32km

Total distance 1.07+0.32=1.39 approximately 1.4km

Ian walked 13/15 miles altogether.

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

Yesterday, Ian walked 2/3 of a mile.

Today, he walked 1/5 of a mile.

To find the number of miles, he walks altogether:

The sum of both the fractions,

2/3 + 1/5

= (2 x 5 + 3 x 1) / 15

= (10+3) / 15

= 13/15

Therefore, he walks 13/15 miles.
