The answer is 16 3/8.

So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.

If a 12 foot ppiece of electrical tape has 5 pieces that are each 1.45 feet cut from it, what is the new length of the tape?

liberstina [14]

4.75 feet, because you would multiply 5 by 1.54 which gives you 7.25 subtract that from 12

Josh has 4 times as many pears as leya, who has one half as many pears as amy. If josh has 32 pears how many does amy have?

arlik [135]

<h3>The number of pears Amy has is 16.</h3>

Step-by-step explanation:

Let J represent the number of pears Josh has.

Let L represent the number of pears Leya has.

Let A represent the number of pears Amy has.

From the question given above,

Josh (J) = 4 × Leya (L)

J = 4L ....... (1)

Leya (L) = ½ × Amy (A)

L = ½A ........ (2)

Next, we shall determine the number of pears Leya has. This can be obtained as follow:

From equation 1

J = 4L

But

Josh (J) = 32 pears

Thus,

32 = 4L

Divide both side by 4

L = 32 / 4

<h3>Leya (L) = 8 pears </h3>

Finally, we shall determine the number pears Amy has. This can be obtained as follow:

From equation 2

L = ½A

But

Leya (L) = 8 pears

Thus,

8 = ½A

Cross multiply

A = 8 × 2

<h3>Amy (A) = 16 pears </h3>

Therefore, Amy has 16 pears.

On babylonian tablet ybc 4652, a problem is given that translates to this equation: x x plus startfraction x over 7 endfraction

seraphim [82]

The correct option is (A). The solution of the equation is x=48.125.

Given an equation $x+\frac{x}{7}+\frac{1}{11}\left(x+\frac{x}{7}\right)=60$ .

A statement that uses the equal sign to show that two expressions have the same value is called an equation. The equation is represented as ax+by=c.

Firstly, we will apply the distributive property to the given equation a×(b+c)=ab+ac, we get

$x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60$

Now, we will simplify the right-hand side equation by taking LCM, we get

$\begin{aligned}\frac{77x+11x+7x+x}{77}&=60\\ \frac{96x}{77}&=60\end$

Further, we will multiply both sides with 77, we get

77×(96x/77)=77×60

96x=4620

Then, we will divide both sides with 96, we get

96x/96=4620/96

x=48.125

Hence, the solution of the given equation $x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60$ is x=48.125.

Andrew buys 4 books for the same price, and also a video for $18. His total bill was $110. What was the cost of a book

Jet001 [13]

First you would subtract 18 from 110 and get a result of 92 then divide by 4 and get 23 so each book is 23 dollars hope this helps mark as brainlist
