15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
romanna [79]

Answer:

x = 14 and 2/3

Step-by-step explanation:

Make an equation where x is the number.

2x - 15 = 7 + 1/2x

Then, solve the equation.

multiply both sides by 2 to get rid of the fraction

4x - 30 = 14 + x

subtract x from both sides

3x - 30 = 14

add 30 to both sides

3x = 44

divide both sides by 3

x = 14 and 2/3

Mrs. Ruiz has 11/12 yard of string to hang 3 banners. She uses the same length of string to hang each banner. How much string do
lesya [120]

Answer:

\frac{11}{36} yard

Step-by-step explanation:

Length of string Mrs. Ruiz has = \frac{11}{12} yard

Mrs. Ruiz needs to hang 3 banners using the string.

Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.

So, we can divide \frac{11}{12} yard by 3 as

⇒ \frac{11}{12}\div 3

Changing the division sing to multiplication by taking reciprocal of divisor.

⇒ \frac{11}{12}\times \frac{1}{3}

We can now multiply numerators and denominators.

⇒ \frac{11}{36} yard

∴  Mrs. Ruiz must used  \frac{11}{36} yard of string for each banner.
