Answer:-43/60

Step-by-step explanation:

-5/12-3/10

You need to start by identifying a common denominator. I used 120, so you need to multiple -5/12 by 10 in the denominator as well as in the numerator. (-50/120). Then for 3/10 you need to multiply the top and bottom by 12 which gives you (36/120). Then you subtract -50/120-36/120. Since it is a negative minus a positive you add the two numerators and get an answer of -86/120 which simplifies to -43/60.

Greata had a price of cloth that is 9 yards long. She cuts it into prices that are each 1/3 yard long. How many prices of cloth

KonstantinChe [14]

Given:

Length of cloth = 9 yards

Length of pieces = $\dfrac{1}{3}$ yards each

To find:

The number of pieces of cloths after cutting.

Solution:

Let n be the number of required pieces.

Length of each piece is $\dfrac{1}{3}$ yards. So, the length of n pieces is $\dfrac{1}{3}n$ yards.

The length of the whole cloth is 9 yards. So, $\dfrac{1}{3}n$ yards must be equal to 9 yards.

$\dfrac{1}{3}n=9$

Multiply both sides by 3.

$n=9\times 3$

$n=27$

Therefore, the Greata have 27 pieces of cloths.

True or False

Hitman42 [59]

Answer:

True

Step-by-step explanation:

To find the average of anything, you add their values together, and then divide that number by how many of them you added.

Here, you are trying to calculate monthly expenditure, so you add their values together (the sum of monthly expenditures) and then you divide it by how many months you used to add up to the sum (divided by the number of months).

Hope this helped ya! :)
