Answer:

x = 19

Step-by-step explanation:

x + (x + 4) + (3x - 9) = 90°

Combine like terms

5x - 5 = 90

Add 5 on both sides

5x = 95°

Divide 5 on both sides

x = 19

The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

------------------------------------------------------------

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Step-by-step explanation: So, she took 2 from each of the volunteers, and there were 5 volunteers in total. What I did, was I found out how many people were taken in total and given to the teachers, which was 10 (2*5), and then I added it to the total number of flyers still with the volunteers (40), which equals 50. Divide that by 5 (number of groups) and you get 10.

Answer:

The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.

Step-by-step explanation:

Answer:

91 scores

Step-by-step explanation:

Let x be the score meg get on fourth test,

Let the total sum of the scores in four test = 45 + 48 + 56 + x (91) = 149 + x

149 + x = 240

x = 91

So to put this in easier words, (45+48+56+91)/4=91

Hence, she should get 91 scores on the fourth test to get an average score of 60.

I hope this helps you, Enjoy!

Answer:

115ft

Step-by-step explanation:

Think of it as two rectangles. One rectangle would be 10ft long and 13-5 or 8ft wide. The other rectangle would be 5ft long and 10-3 or 7 ft wide. Find the area of the two rectangles and add them. Rectangle 1= 10•8 or 80ft. Rectangle 2= 5•7 or 35ft. 80+35=115ft. Juan would need at least 115ft of rubber flooring.

Answer:

104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people

Answer:

n=2

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

Hello! I believe that I have the answer.

My answer: The total amount was $47.79.

8% of $37.50 is $3. $37.50 + $3 = $40.50.

18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.

I hope that helps! Please let me know if my answer is incorrect.

The scatter plot diagram that represents the data that is shown in the given table is; Attached below

We are told that;

the x-axis represents the beginning balance in thousands of dollars.

the y-axis represents the change in the bank account by hundreds of dollars.

Now, this means the values on the x-axis in plotting order from left to right with their corresponding y-values are;

x - values = 6, 4, 3, 1, 8, 3, 4, 5

y - values = 6, 5, 2, 5, 4, 8, 2, 3

Thus, to plot the scatter diagram, we will enter the corresponding x and y coordinate values which are seen in the scatter diagram attached.

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Part A:

(larger)

(multiply)

(32)

Part B:

you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)

and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee

Answer:

its 7ft

Step-by-step explanation:

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

Answer:

30

Step-by-step explanation:

Lets use the formula BEDMAS:

-6 × -3 = 18 (Since two negatives equals a postive)

18 - 8 = 10

We have a first bracket done, so lets do the next one:

-6 ÷ -2 = 3

-----------

In the middle, the is a multiply symbol, so

10 × 3 = 30

----------

Have a good day :)
