Question 3
Write an equivalent expression to 13.4x - 5.9 - 7.1x + 13.5 with the fewest possible terms.

Answer:

Step-by-step explanation:

Let's start by weighing everything but the assignments. We'll get back to them momentarily.

You have 85% on 45% of your grade. That's 38.25

Your final weighs in at 20%. You have.           18

So your total so far is                                        56.25

Now that looks mighty low, but we haven't put in the assignments yet.  

So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%

So your assignment mark will be 0.65 * 85.41 = 55.52

The weighted average = 0.35

The mark you will get is 0.35 * 55.52 = 19.32

So your final grade will be                      56.25  

Grade                                                        75.57

In Canada (where I live), that would be a solid B. I don't know how things are calculated in the US, but I have done the work properly, I think.

The Net Force is the difference of force. In this case

10N to the left - 5 N to the right = 5N to the left

Answer:

7-2x=y

Step-by-step explanation:

When a point passes through a line it satisfies its equation

(X-x0 )m= y-y0

Slope = m = -2

(X-2 )(-2)=y-3

4-2x=y-3

7-2x=y

Their account balances will never be equal.

Step-by-step explanation:

I basically ran the math. 500 minus 12 times anything from 1-40 cannot equal 600 minus 15 times anything from 1-40. When we come to 600 - (15*40) we get zero.

Answer: The wrestler won 45% of their matches.

Step-by-step explanation:

When are trying to find percentages, we are finding part of a whole. 31 is the whole and the part is 14.

If I was to set [tex]\frac{14}{31}[/tex] to an equivlent fraciton of over 100, we would get something close to 45.

Answer:

2(x+7)(x-7)

Step-by-step explanation:

1. In 2x^2-98, there is a common factor of 2

2. The equation therefore becomes 2 (x^2 - 49)

3. We know that x^-49 is a difference of two squares and can therefore be factored into (x+7)(x-7)

4. Therefore the fully factored answer is 2(x+7)(x-7)

Answer:

ur screwed go with b

Step-by-step explanation:

Answer:B The graph of g(x) is the graph of f(x) compressed vertically. The factor of compression is 2/5 and is less than 1 so it is compressed instead of stretch if the factor was greater than 1. There is no reflection across the x-axis because there is no negative sign in front of the function f(x).

JUST ANSWER B

Answer:

Rises to the left and falls to the right

Step-by-step explanation:

Use the degree and the leading coefficient to determine the behavior.

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Function is a type of relation, or rule, that maps one input to specific single output.

The function f(x) is defined as;

f(x)= 123x³+9[tex]x^4[/tex] - 768x - 3[tex]x^5[/tex] - 189x² + 1260

WE need the degree and the leading coefficient to determine the behavior.

Since our leading coeffeicent has a leading even degree of 5, and a positive number,

The function will Rises to the left and falls to the right.

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Answer:

Angel has a greater ratio of pencils to pens.

i.e. Angle's pencils to pens = 3 / 2 or 63/42

Thus, option (B) is true.

Step-by-step explanation:

Considering the table

Lydia's Number of Pencils = 10

Lydia's Number of Pens = 7

Lydia's Pencils to Pens ratio = 10/7

Angel's Number of Pencils = 9

Angel's Number of Pens = 6

Angels's Pencils to Pens ratio = 9/6 = 3 / 2

Elizabeth's Number of Pencils = 12

Elizabeth's Number of Pens = 9

Elizabeth's Pencils to Pens ratio = 12/9 = 4 / 3

So, We get the inputs ratios such as:

Lydia's ratio:  Angels's ratio: Elizabeth's ratio

      10/7      :         3 / 2         :        4 / 3

As the least common denominator (LCD) is: 42

Rewriting as equivalent fractions with the LCD:

10/7            :         3 / 2         :        4 / 3

60 / 42       :        63/42       :       56/42

Sorting from least to greatest:

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

Elizabeth's ratio       :         Lydia's ratio       :    Angels's ratio:  

4/3                             :         10 /7                  :        3 / 2

56/42                        :          60 / 42             :         63/42

Therefore, Angel has a greater ratio of pencils to pens.

i.e. Angle's pencils to pens = 3 / 2 or 63/42

Thus, option (B) is true.

Answer:

associative property

Step-by-step explanation:

identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged.  and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)

Answer:

RP = 2.3

PQ = 1.0

RQ = 2.3

Step-by-step explanation:

The pictures says RP = RQ,

so:

3x - 0.4 = x + 1.4

this you can simplify to:

x = 0.9

Then fill x in:

RP = 3*0.9 - 0.4 = 2.3

PQ = 0.9 + 0.1 = 1.0

RQ = 2.3

The inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the total number of DVDs Martin can buy be = A

Now , the equation will be

The price of 1 DVD is = $ 8.50

The price for shipping and handling = $ 5.00

Now , the total amount Martin decides to spend = not more than $ 56

So , the inequality equation will be

8.50A + 5 ≤ 56

On simplifying the equation and solving for A , we get

Subtracting 5 on both sides of the equation , we get

8.50 A ≤ 51

Divide by 8.50 on both sides of the equation , we get

A ≤ 51 / 8.5

A ≤ 6 DVDs

So , the value of A should be less than or equal to 6

Hence , the inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy
