What is: 2x/7 - 18 = 6

Mathematics
2 answers:
aalyn [17]3 years ago

Answer:

<h2>x = 84 </h2>

Step-by-step explanation:

\frac{2x}{7}  - 18  = 6

<u>Add 18 to both sides of the equation</u>

That's

\frac{2x}{7}  + 18 - 18 = 6 + 18 \\  \frac{2x}{7}  = 24

Multiply through by 7 to eliminate the fraction

7 \times  \frac{2x}{7}  = 24 \times 7 \\ 2x = 168

<u>Divide both sides by 2</u>

\frac{2x}{2}  =  \frac{168}{2}  \\

We have the final answer as

<h3>x = 84</h3>

Hope this helps you

<h3>Given:</h3>

\frac{2x}{7}  - 18 = 6

<h3>To Find:</h3>

The value of x.

<h3>Solution:</h3>

By adding 18 to both the sides, we get

\frac{2x}{7}  = 24

By taking 7 to the RHS, we get

2x = 24 \times 7 = 168

By taking 2 to the other side, we get

x =  \frac{168}{2}  = 84

<h2>Answer:</h2>

The value of x is 84.

Aubree practices the piano 1197 minutes in 3 weeks. At what rate did she practice, in minutes per day?
Norma-Jean [14]

Answer:

57

Step-by-step explanation:

We need to create a ratio. so Aubree practices the piano for 1197 min: in 3 weeks. So for 1 week, we have to divide 1197 by 3, so 1197/=399. And so we know that 1 week is 7 days, just divide 399 by 7! 399/7=57. The rate that she practiced per day is 57 minutes. So one last final step just to check if this answer is correct is to divide 57 by 60, and that is 0.95. 0.95 out of 1.00 minutes per day is 95/100. Cross multiply with x/60, and you will get your answer, which is 57.

A family buys 6 airline tickets online. The family buys travel insurance that costs ​$17 per ticket. The total cost is ​$1 comma
Sedbober [7]

Answer:

1020 = 6*(x+17)

x = 153

Step-by-step explanation:

1020 = 6*(x+17)

1020 - total

6 - number of tickets

x - one ticket price

17 - insurance

1020 = 6x + 102

1020 - 102 = 6x

918 = 6x

x = 918/6

x = 153
