The first thing to do is to convert the mixed numbers to improper fractions
5 3/8= 43/8

3 5/8 = 29/8

since they have the same denominators
SUBTRACT  the numerators and bring down the denominator
43-29= 14/8= 1 3/4 miles

Hope this helps

What’s the least common multiple of the denominators of 9+3/4x=7/8x-10
Alona [7]

Answer:

x = 72

Step-by-step explanation:

9 +  \frac{3}{4} x =  \frac{7}{8} x - 10 \\  \frac{3}{4}x  -  \frac{7}{8} x =  - 10 - 9 \\  \frac{6}{8} x -  \frac{7}{8} x =  - 19 \\  -  \frac{1}{8}x =  - 19 \\ x =  \frac{ - 9}{ -  \frac{1}{8} }  \\ x = 72

If f(x)=2x^2+3x+1 and g(x)=x+5, what would f(g(x))
Fantom [35]

Answer: The answer is 2x^2+23x+66.

Step-by-step explanation: The given functions are

f(x)=2x^2+3x+1,\\\\g(x)=x+5.

We are to find f(g(x)). To do this, first we need to evaluate g(x) and then we will apply the function f on the resulting function.

The evaluation is as follows:

f(g(x))=f(x+5)=2(x+5)^2+3(x+5)+1=2(x^2+10x+25)+3x+15+1\\\\\Rightarrow f(g(x))=2x^2+23x+66.

Thus, the correct answer is 2x^2+23x+66.

PLZ answer quick!!!!!

Number of items sold by Shelley = 3 items.

Let us assume cost of each item sold by Shelley = $ x each.

Total cost of 3 items for Shelly sold = 3*x = 3x.

Number of items sold by Billy Bob = 4 items.

The cost of each item sold by Billy Bob = $2.25 less than the items that Shelley bought = $(x-2.25) each.

Total cost of 4 items for Billy Bob sold = 4*(x-2.25) = 4(x-2.25).

Both Shelley and Billy Bob paid the same amount of money. So, we can setup an equation now.

a) Total cost of 4 items for Billy Bob sold=Total cost of 3 items for Shelly sold.

4(x-2.25) = 3x

b) Solving equation for x now.

Distributing 4 over (x-2.25), we get

4x - 4*2.25 = 3x.

4x -9 = 3x.

Adding 9 on both sides, we get

4x -9+9 = 3x+9

4x =3x+9.

Subtracting 3x from both sides, we get

4x-3x =3x-3x+9.

x = 9.

c) Checking the solution of the equation by plugging x=9 in equation we got above.

4(x-2.25) = 3x  => 4(9-2.25)= 3*9

               => 4*6.75 = 27

               => 27 = 27.

We got left side = right side. So the solution x=9 is correct.

d) The cost of each item sold by Billy Bob = 9-2.25 = $6.75

Therefore, the cost of each item sold by Shelley is $9 and cost of each item sold by Billy Bob is $6.75.
