Answer:

A rational number is a number able to be put into a fraction, an irrational number is not able to be. Therefore, when adding the two, the rational and the irrational will be irrational. For example, 2 is a rational number, and 1.8903 is irrational. If you add the two, you will get 3.18903, which is unable to be put into a fraction.

Solve for y:<br><br> -y+6+6y=9
Marina CMI [18]
-y + 6 + 6y = 9

First, simplify -y + 6 + 6y to 5y + 6. / Your problem should look like: 5y + 6 = 9
Second, subtract 6 from both sides. / Your problem should look like: 5y = 9 - 6
Third, subtract 9 - 6 to get 3. / Your problem should look like: 5y = 3
Fourth, divide both sides by 5. / Your problem should look like: y =  \frac{3}{5}

Answer as fraction: y = \frac{3}{5}

Help asap thank you!!!!!
viktelen [127]

Answer:

A = 120

C = 45

Step-by-step explanation:

(12x + 12) + 15 + (3x + 18) = 180

(12x + 3x) + (12 + 15 + 18) = 180

15x + 45 = 180

15x = 180 - 45

15x = 135

x = 135/15

x = 9

A = 12x + 12 = 12(9) + 12 = 108 + 12 = 120

C = 3x + 18 = 3(9) + 18 = 27 + 18 = 45

1/2(4x-5) + 5/2 = 10

Use the distributive property:

2x - 5/2 + 5/2 = 10

Use addition property:

2x = 10

Divide both sides by 2:

x = 10/2

x = 5

zhenek [66]
4 miles = 1 day

4miles divided by 1/3 distance on 2nd day = 1.33 miles ran on second day
4/1 x 1/3=4/3   4 divided by 3= 1.33 miles ran on the second day
If Will ran 1/3 of the distance that he ran on the first day (4 miles) the second day, he ran 1.33 miles
