7(x+10)=100 how do u find what x equals

Answers

Answer 1

Answer: 7(x + 10) = 100

First, divide both sides by 7. / Your problem should look like: $x + 10 = (100)/(7)$
Second, subtract the 10 from both sides. / Your problem should look like: $x = (100)/(7) - 10$
Third, simplify. / Your problem should look like: $x = (30)/(7)$

Answer as fraction: $x = (30)/(7)$
Answer as decimal: 4.2857

Madelyn jokes 190.5 meters up a mountain . I’d she is 62 percent of the way up how tall is the mountain?

Answers

The mountain is 307.26 meters tall.

Step-by-step explanation:

Given,

Distance jogged by Madelyn = 190.5 meters

This represents 62 percent of total height of mountain.

Let,

x be the height of mountain.

62% of x = 190.5

$(62)/(100)*x=190.5\n0.62x=190.5$

Dividing both sides by 0.62

$(0.62x)/(0.62)=(190.5)/(0.62)\nx=307.258$

Rounding off to 2 decimal places

x = 307.26 meters

The mountain is 307.26 meters tall.

The meal costs $7.50. She wants to leave a 20% tip.

A 10% tip would be 75 cents ($0.75), because 7.5 / 10 = 0.75.

A 20% tip would be $1.50 because 7.5 / 5 = 1.50

You can also multiply the 10% answer by 2 to get the same number.
