Answer:

with discount+tax= $23.15

Step-by-step explanation:

board game is 25

discount: 15%

tax: 7.5%

discount means you take off that amount

tax means you add that amount

discount: 15% off

tax: +7.5%

to find 15% of 25 multiply 25 by 15% (15/100=0.15)

25*0.15

= 3.75

then subtract that from 25

25-3.75

=21.25

tax:

0.075*25

=1.875

~1.9

21.25+1.9

=23.15

Answer: Choice A) If Amber and Jorge each sell 5 trees in one week, they will earn the same amount

The amount they earn is $200 each.

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

Explanation:

Let's form the equation for the amount Amber earns.

She starts off at $150, and then we add on 10x dollars. The 10x is because she earns 10 dollars per tree, and we have x be the number of trees sold.

Overall we can say her equation is y = 150+10x

This is the same as y = 10x+150

----------

Since Jorge's equation is y = 25x + 75, we can apply substitution to solve for x

y = 10x+150

25x+75 = 10x+150 .... replace y with 25x+75

25x+75-10x = 150 ... subtract 10x from both sides

15x+75 = 150

15x = 150-75 ... subtract 75 from both sides

15x = 75

x = 75/15 .... divide both sides by 15

x = 5

If they sell 5 trees per week, then Amber and Jorge earns the same amount of money.

That amount earned is

Amber: y = 10x+150 = 10*5+150 = 50+150 = 200 dollars

Jorge: y = 25x+75 = 25*5+75 = 125+75 = 200 dollars

Both earn $200 per week from selling 5 trees for that week. This helps confirm we have the right answer.

The value of [tex]\frac{14}{8} + \frac{15}{12}[/tex]  = 3

Step-by-step explanation:

Explanation

Given       [tex]\frac{14}{8} + \frac{15}{12}[/tex]

L.C.M     8 , 12   is  24

       [tex]\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}[/tex]

                  = [tex]\frac{42 +30}{24} = \frac{72}{24} = 3[/tex]

Final answer:-

The value of [tex]\frac{14}{8} + \frac{15}{12}[/tex]  = 3

Answer:D

Step-by-step explanation:its the same thing but the numbers are flipped, you get the same answer either way.

The statement that illustrates the commutative property of addition is

8i + 4 = 4 + 8i. The correct option is D.

The commutative property of addition:

Let a and b are numbers.

a + b =  b + a

The change in the position of two numbers in an addition operation does not change the sum.

The commutative property of addition:

Let a and b are numbers.

So, a + b =  b + a.

LHS = 8i + 4

= 2 (4i+2)

= 2(2 + 4i)

=  4 + 8i

That means,  8i + 4 = 4 + 8i holds the commutative property of addition.

Therefore, the equation is 8i + 4 = 4 + 8i.

Answer: 2.68

Step-by-step explanation: 0.4 + 0.68 + 1.6

Answer:

12/4 * 3 or 3 ÷ 12/4

Step-by-step explanation:

Don't worry, I got you covered.

First, you examine the words in the sentence. After you look at the key-words, which would be "12 fourths in 3." This would translate to 12/4 into 3. Here's the examples.

Start by dividing rather than multiplying for your first equation.

3 ÷ 12/4. If you want 3 to be equal to 12/4 in division, you want to take the largest number and divide it into the smaller number. In this case, the large number would be 3 while the small number would be 12/4. It still makes it correct, despite you changing the problem a bit.

This would get you the easiest way to use your division.

Finally, try making a multiplication problem. If you want there to be 3 equal to 12/4, another justification could be 12/4 * 3. This would keep the problem true, while still solving the missing equation.

50 Pick me brainliest

Step-by-step explanation:

Answer:

x = 50

Step-by-step explanation:

These angles are vertical angles. Vertical angles are congruent to each other. Therefore, 3x° = (2x+50)°

Subtract 2x from each side.

x=50

-3 = 13 - 15x  | subtract -13 on both sides

-16 = 15x  | divide 15 on both sides

-1 = x  | final answer is B. -1

Answer:

Equation: X-1.35= 2.30

Value of X: x=3.65

Step-by-step explanation:

You can choose whatever variable you want to represent the original amount of money Jennifer had in her pocket. I decided to use X as my variable.

If X represents the original amount of money Jennifer had in her pocket, then I can write this equation:

X-1.35= 2.30

Essential what this equation shows is that Jennifer spends $1.35 of what she originally has, which is x. After she spends that she's left with $2.30. This is how we solve for x, also known as the original amount Jennifer had in her pocket:

X-1.35= 2.30

(we will add 1.35 to each side because we what to balance out the equation and the inverse operation of subtraction is addition)

X= 3.65

So Jennifer originally had $3.65 in her pocket before she spent the $1.35

Answer:

a. The value of x is [tex]38^{o}[/tex].

b. The value of y is [tex]25^{o}[/tex].

Step-by-step explanation:

a. Applying the vertically opposite principle,

(2x + 5) = (3x - 33)

2x + 5 = 3x - 33

33 + 5 = 3x - 2x

38 = x

⇒ x = [tex]38^{o}[/tex]

b. Sum of angles on a straight line = [tex]180^{o}[/tex]

So that,

(4y - 1) + (3x - 33) = [tex]180^{o}[/tex]

But,

( 3x - 33) = (3x38 - 33)

               = 114 - 33

               = [tex]81^{o}[/tex]

(4y - 1) + [tex]81^{o}[/tex] = [tex]180^{o}[/tex]

4y - 1 = [tex]180^{o}[/tex] - [tex]81^{o}[/tex]

         = [tex]99^{o}[/tex]

4y = [tex]99^{o}[/tex] + 1

    = [tex]100^{o}[/tex]

y = [tex]\frac{100}{4}[/tex]

  = [tex]25^{o}[/tex]

y = [tex]25^{o}[/tex]

The value of x is [tex]38^{o}[/tex], and y is [tex]25^{o}[/tex].

Answer: Working or doing homework in bed will reduce one's focus because most people tend to associate their beds with comfort and sleep. Doing such activities in bed can lead to a deviation of the brain to become more lazy and possibly fall asleep.

Disadvantages of studying in bed includes issues related to posture and concentration. Hence, studying in bed often ;

A bed is primarily meant for sleeping while desks and chairs are made for studying. The difference in the build is due to the purpose of nature of each activity. Studying in an environment meant for sleeping would most likely induce sleep.

Similarly the structure or design of a bed isn't appropriate for studying and may likely affect the rate of assimilation.

Answer:

The probability is 0.16602

Step-by-step explanation:

We start by calculating the z-score

We have this mathematically as;

z-score = (x-mean)/SD/√n

From the question,

we have x = 6.15

mean = 6.06 hours

standard deviation = 0.55 hours

n = 35

Substituting these values, we have

z-score = (6.15-6.06)/0.55/√35

z-score = 0.09/0.55/5.92

z-score = 0.97

So the probability we want to calculate is:

P ( z > 0.97)

we make use of the standard normal distribution table here

The value is; 0.16602

Answer:

0.40

Step-by-step explanation:

Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

7.2 ÷ 18 = 0.40

and therefore:

0.72 ÷ 1.8 = 0.40

Both calculated to 2 decimal places.
