Answer:

6

Step-by-step explanation:

3n = n + 12

2n = 12

n = 6

Answer:

6

Step-by-step explanation:

let the number be x , then

3x = x + 12 ( subtract x from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

That is the number is 6

Answer:

12.5 days

Step-by-step explanation:

Given

No of workers= 30

Time taken to paint shopping mall= 25 days

Assume time taken for 15 men =X

Time taken for 15men to paint X= (15*25)/30

=12.5 days

Answer:

(x + 7) = 41

Step-by-step explanation:

Let the number of lions in the wildlife reserve = x

Since, 7 lion cubs were born, so the total number of lions in the wildlife reserve will be (x + 7)

Now total number of lions = 41

Therefore, equation representing this situation will be,

(x + 7) = 41

Answer:

x=5 30 degrees

Step-by-step explanation:

theres 90 degrees in the right angle and you already have 60 degrees so you know it has to equal to 90 degrees so it has to be 30 degrees and 6 x 5 is equal to 30

Answer:

B

Step-by-step explanation:

We can determine the total miles run by the 10 students by adding all the miles run by each individual student:

A

1 student * 1/12 miles = 1/12 miles

2 students * 1/8 miles = 2/8 miles = 1/4 miles

1 student * 1/6 miles = 1/6 miles

2 students * 1/4 miles = 2/4 miles = 1/2 miles

1 student * 1/3 miles = 1/3 miles

3 students * 1/2 miles = 3/2 miles

We add all these fractions to obtain 17/6, which is approximately 2.83, which is not as the question describes.

B

2 students * 1/6 miles = 1/3 miles

2 students * 1/4 miles = 1/2 miles

2 students * 1/3 miles = 2/3 miles

3 students * 1/2 miles = 3/2 miles

1 student * 1 mile = 1 mile

We add all these fractions to obtain 4 miles, which is as the question describes.

Answer:

29

Step-by-step explanation:

x+11÷8=5

5 × 8 = 40

40- 11 = 29

29 + 11 ÷ 8 =5

Answer:

Step-by-step explanation:

The required simplified value of the expression 150/8 is 18.75. Option D is correct.

To simplify the expression 150/8, using arithmetic operations,

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
To simplify 150 / 8 as where "/" is the division operator,
So,
150 / 8 = 18.75

Thus, the required simplified value of the expression 150/8 is 18.75. Option D is correct.

Answer: A) Yes, it is a solution.

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

Explanation:

Replace every x with -3 and simplify both sides.

3x - 2 < 2 - 2x

3(-3) - 2 < 2 - 2(-3)

-9 - 2 < 2 + 6

-11 < 8

Since -11 is to the left of 8 on the number line, this means the inequality -11 < 8 is true. Consequently, it means the first inequality is true when x = -3.

Therefore, x = -3 is a solution.

Answer:Answer:

13.0feet

Step-by-step explanation:

Given ΔDEF with ∠F=90°, the measure of ∠D=19°, and DE = 40 feet, since one of the angles of the triangle is 90°, the triangle is a right angled triangle as shown in the attachment.

Using SOH, CAH, TOA to get the unknown EF.

Since <D is opposite to side EF, EF will be the opposite while side DE will be the hypotenuse

Based on SOH:

Sin<D = Opposite/Hypotenuse

Sin<D = EF/DE

Sin19° = EF/40

EF = 40sin19°

EF = 13.0 feet to the nearest tenth of a foot

the answer is 1

as the formula is:

m= -coefficient of x / coefficient of y

where coefficient of x is 1 and coefficient of y is -1

Answer:

8 (3.8 + 4)

Step-by-step explanation:

x=3.8

Answer:

x = 4

y = 11

Step-by-step explanation:

Set  your formula as follow:

2x+3=3x-1 -> 2x+3-3x=-1  -> -x+3 = -1 -> -x=-4 -> x=4

now substitute x for 4 in the following

y-2=2(4)+1 -> y-2=8+1 ->y-2 = 9y -> y=11

Answer:

x= 4

To Obtian the number of cans of paints to be purchased;

1.) Find the area of the penthouse in feet². This gives the value of the whole area of the penthouse to be painted.

2.) since 1 can of paint is said to cover 24 feet²

3.) Divide the area of the penthouse by 24 feet² ; this will give the number of cans of paints to be purchased.

By taking the simple steps above, the number of cans of paints needed will be obtained.
