I believe it would be x>7/3
<span>So we want to know how much does the pencil costs if the ruler costs 1$ more than the pencil and together they cost 1.5$. So lets start with converting dollars into cents. Lets turn this into an equation. Ruler is x and the pencil is y. So together ruler and pencil cost 150cents or: x+y=150 cents. The ruler costs 100 cents more than the pencil, or: (x+100 cents ) + y = 150 cents. So we see that we need to put the values of x=25 cents and y=25 cents to get the ruler to cost 125 cents which is 100 cents or 1$ more than the pencil. So the pencil costs 25 cents. </span>
Answer:
700,000
Step-by-step explanation:
okay so to increase something by 7% you have to multiply it by 1.07
so if you divide it by 1.07, you'll find the original price
749,000 ÷ 1.07 = 700,000
Answer:
Step-by-step explanation:
The formula for calculate the volume of a sphere is shown below:
Where V is the volume of the sphere and r is the radius of the sphere.
The problem says that the radius of the sphere is 8. Then, you only need to substitute this value into the formula shown above.
Therefore, you can calculate it as following:
Let the number of years be x.
11 + x = 2( 3 + x)
11 + x = 6 + 2x
x = 11 - 6
x = 5
