Answer:

1: X= 8, 2: 2/5 or 0.4

Step-by-step explanation:

1: 2(2x + 1) + x = x + 2x + 18

5x + 2 = 3x + 18

2x = 16

x = 8

2: 2x + x + 2x = 10 + x

5x = 10 + x

4x = 10

x = 4/10

x = 2/5

x = 0.4

How do you write 3 7/10 as a decimal
Leokris [45]

Answer:

3.7

Step-by-step explanation:

To change a fraction to a decimal, just divide the numerator with the denominator. Instead of placing the remainder over the divisor, continue to solve until it is answered (unless it's a repeating decimal.)

Divide 7 with 10:

7/10 = 0.7

Remember that there is a whole number, 3. Add that to the decimal you have gotten:

3 + 0.7 = 3.7

3.7 is your answer.
