Can I get the steps of solving the fractions ?

Paul [167]3 years ago

Step-by-step explanation:

In adding fractions, first you have to make the denominators the same. To do this, you need to find the GCF (greatest common factor).

3/4 + 4/8  

The GCF on this would be 8, since both 4 and 8 can go into it. Next, you need to change both the denominators to the GCF, but you have to make sure the fractions are still equal to the original one. To do this, you have to multiply the numerator by the amount the original denominator is multiplied to get to the GCF.

4(2) = 8

3(2) = 6

So now you have 6/8 + 4/8. Next, you just add up the numbers normally, leaving the denominators the same.

6/8 + 4/8 = 10/8

If necessary, you simplify the fraction. To do this, you need to find the smallest number that goes into both of them, besides one. In this case, it would be 2. Then, you divide both the numerator and denominator by that number.

10/2 = 5

8/2 = 4

Then, to find the most simplified version, you need to divide the numorator by the denominator.

5/4 = 1 with a remainder of 1.

You put your answer as the whole number, and your remainder as the numorator. Leave the denominator the same.

1\frac{1}{4}

Hope this helped with adding fractions!

AUTOMOBILES The engine torque y (in foot-pounds) of one model of car is given by y = º3.75x2 + 23.2x + 38.8 where x is the speed
Scilla [17]

Answer:

Part 1) The engine speed that maximizes torque is 3,093 rev/min

Part 2)The maximum torque is 74.683\ foot-pounds

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y=-3.75x^{2}+23.2x+38.8

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The x-coordinate of the vertex represent the engine speed that maximizes torque

The y-coordinate of the vertex represent the maximum torque

Solve the quadratic equation by graphing

using a graphing tool

The vertex is the point (3.093,74.683)

see the attached figure

therefore

The engine speed that maximizes torque is

3.093(1,000)=3,093 rev/min ---> because is in thousands of revolutions per minute

The maximum torque is

74.683\ foot-pounds

Need a answer soon I am taking a test <br> 70 divide by 14 +54 divide by 9
algol13

<u>Answer:</u>

11

<u>Step-by-step explanation:</u>

We are given the following expression and we are to solve it:

\frac {70} {14} + \frac {54} {9}

Simplifying both the fractions before adding them to make it easier to solve:

= \frac {70} {14} + \frac {54} {9}

= 5 + 6

= 11

Therefore, the answer to the given mathematical expression is 11.
