Answer:

A) three-fourths of a number plus two

Step-by-step explanation:

To find out what the answer is, we first need to translate the sentence into numbers, which will give us:

\frac{3}{4}x+2

We can see that we are multiplying an unknown number, x, by three fourths, so we know that we are taking three-fourths of a number, and we also know that we are then adding two. We are not dividing or subtracting, so we know it can't be  B or D. We also know that we are multiplying three-fourths by x, not two so we know that it can't be C. So our only option is A, So the correct answer is:

A) three-fourths of a number plus two

Answer:

Three-fourths of a number plus two

Step-by-step explanation:

The value "x" is  used in algebra to mean a value that is not yet known.

Remember the algebraic expression is: 3/4x + 2

Lets break each possible answer down,

<em>1. The quotient of four-thirds and two is:  </em>4/3 ÷ 2

<em>2. The product of three-fourths and two is:  </em>3/4 * 2

<em>3. The difference between three-fourths of a number and two is:</em>

3/4x - 2

None of these expressions match 3/4x + 2, which brings us to the last answer.

<em>4. Three-fourths of a number plus two </em>is:  3/4x + 2

Notice, "x" is represented as "<em>of a number</em>", since the value is unknown.

Therefore, your answer is A, three-fourths of a number plus two.

The sum of squares of two consecutive positive even integers is 52 more than their product. Find these numbers.
natulia [17]

Answer:

The first set of consecutive even integers equals (8 , 6)

The second set is ( - 8 and - 6) which also works.

Step-by-step explanation:

Equation

(x)^2 + (x + 2)^2 = (x)(x + 2) + 52            Remove the brackets on both sides

Solution

x^2 + x^2 + 4x + 4 = x^2 + 2x + 52        Collect the like terms on the left

2x^2+ 4x+ 4 = x^2 + 2x + 52                  Subtract right side from left

2x^2 - x^2 + 4x - 2x + 4 - 52  =  0          Collect the like terms

x^2 + 2x - 48 = 0                                     Factor

(x + 8)(x - 6) = 0

Answer

Try the one you know works.

x - 6 = 0

x = 6

Therefore the two integers are 6 and 8

6^2 + 8^2 = 100

6*8 + 52  = 100

So 6 and 8 is one set of  consecutive even numbers that works.    

========================

What about the other set.

x + 8 = 0

x = - 8

x and x + 2

- 8  and -8 + 2 = - 8, - 6

(- 8 )^2 + (- 6)^2 = 100

(-8)(-6) + 52 = 100

Both sets of consecutive numbers work.

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams. (Note 1 kilogram=35 ounces)
n200080 [17]

Answer:0.8 kilograms

800 grams

Step-by-step explanation:

The weight of Tyler's baseball bat is 28 ounces. We would convert the weight in ounces to kilogram and grams.

Let x represent the number of kilograms that is equal to 28 ounces. Therefore

1 kilogram = 35 ounces

x kilogram = 28 ounces

Cross multiplying, it becomes

35 × x = 28 × 1

35x = 28

x = 28/35 = 0.8 kilograms

We would convert 0.8 kilograms to grams

Let y represent the number of grams that is equal to 0.8 kilograms. Therefore,

1000 grams = 1 kilogram

y grams = 0.8 kilograms

Cross multiplying,

y × 1 = 0.8 × 1000

y = 800 grams

I don't need the answer I NEED someone to explain this to me, I'm really struggling with this, and can someone walk me through t
Whitepunk [10]
<h2>Answer:</h2>

I hope it will helps u

<h2>Step-by-step explanation:</h2>

As given

x²-3x-10

Now according to the one of the rule of factorization ,

we have to find such two values whose product becomes equal to the

"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".

so such numbers are   -5x and +2x

if we add or multiply them we get the above

as  adding    -5x+2x=-3x  (middle term)

also multiplying   -5x*2x=-10x²  (product of 1st and last term)

so now , we can write as,

x²-3x-10

=x²-5x+2x-10

now making groups of 2 terms,

=(x²-5x)+(2x-10)

now common

=x(x-5)+2(x-5)

now common(x-5)

=(x-5)(x+2)   This is the required factors.....
