Answer:

[tex]\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}[/tex]

Step-by-step explanation:

We have the expression:

[tex]\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x}[/tex]

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x

We will get:

[tex](\frac{2}{2} )\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x}[/tex]

Now we can directly add the terms to get:

[tex]\frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x} = \frac{x - 6}{4*x}[/tex]

We can't simplify this anymore

Answer:

11/4

Hope this helps

Answer:

11/4

Step-by-step explanation:

An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.

You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8

then we add 8/4 with 3/4 to get 11/4

Answer:

A - 6:24

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

OA = OD ( both radii of the circle )

OD = OB + BD = x + 16

OB is at right angles to OB ( line from centre to midpoint of chord is right )

Using Pythagoras' identity in right triangle ABO

OA² = OB² + AB² , that is

(x + 16)² = x² + 24²

x² + 32x + 256 = x² + 576 ( subtract x² from both sides )

32x + 256 = 576 ( subtract 256 from both sides )

32x = 320 ( divide both sides by 32 )

x = 10

Solve the equation for  x  by finding  a ,  b , and  c  of the quadratic then applying the quadratic formula.

Exact Form:

x= -9±[tex]\sqrt{17}[/tex] / 16 (over 16)

Answer:

A [tex]\frac{1}{8}[/tex]

Step-by-step explanation:

[tex]\frac{1}{2}[/tex]÷4=[tex]\frac{1}{2}[/tex]·[tex]\frac{1}{4}[/tex]=[tex]\frac{1}{8}[/tex]

Dividing by four is also the same as multiplying by it's reciprocal which is [tex]\frac{1}{4}[/tex].

Answer:

1/8

[tex]\frac{1}{2}[/tex] ÷ 4

[tex]\frac{1}{2}[/tex]÷[tex]\frac{4}{1}[/tex]

The second fraction flips.

[tex]\frac{1}{2}[/tex]×[tex]\frac{1}{4}[/tex]

Multiply across.

[tex]\frac{1}{2}[/tex]×[tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex]

Answer:

4024.62

Step-by-step explanation:

the value in 70 days can be determined using his formula

FV = P (1 + r)^n

FV = Future value  

P = Present value = 650

R = growth rate = 20%

N = number of weeks = 70 / 7 = 10 weeks

650 x (1.2)^10 = 4024.62

Answer:

The Answer is 4024.62

Answer:

1/ 8 ^2

Step-by-step explanation:

When we are dividing exponents with same base all we do is subtract the denominator by the numerator (the exponent)

In this scenario we have  8^3 / 8^5

We are saying 8 * 8 * 8 / 8 * 8 * 8 * 8 * 8   When we cancel out the 8's were left with 1 / 8^2

or we could just subtract if that method is too long

Answer:

500N

Step-by-step explanation:

Given data

Mass m= 50kg

Acceleration a= 10m/s^2

We know that the expression for the force is

F=ma

Substitute

F= 50*10

F= 500N

Hence the applied force is 500N

Answer:

332

Step-by-step explanation:

To find how many seats there were, multiply the number of rows with the number of seats in each row:

15 (24) = 360

From these total seats, there are 28 empty seats, meaning:

360 - 28 = 332

There were 332 people.
