How to solve it step by step

Answer:

n = -5

Step-by-step explanation:

Step 1: Write equation

-n + 7 - 2n + 5n - 3 = -6

Step 2: Solve for n

Combine like terms: 2n + 4 = -6

Subtract 4 on both sides: 2n = -10

Divide both sides by 2: n = -5

Step-by-step explanation:

Answer:

mid point (x,y) = M (18, 24)

let J (- 4, - 2) be ( x1, y1)

     L(a,b) be (x2,y2)

using midpoint formula

(x,y) = [(x1+x2)/2, (y1 + y2)/2]

or, (18, 24) = [(-4+a)/2, (-2+b)/2]

comparing corresponding element we get

18 = (-4+a)/2                 24 =(-2+b)/2

or 36 = -4+ a            or 48 = -2 +b

or a = 40                  or b= 50

L(40,50)

Answer:

7:21   For every student wearing a blue shirt, there were 3 students wearing red shirts.

Step-by-step explanation:

If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.

That means the ratio of blue shirts to red shirts is 7:21

That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.

We get this because 21/7 = 3  and 7/7 = 1

Answer:

You can tell 7.360 and 7.36 are equivalent decimals because when you put a zero in the decimal places, it doesn't count as a number and it doesn't have a value. In conclusion, zero is just a placeholder. Therefore, if you have the zero or not it doesn't matter.

Answer:

She bought 19 chicken wings

Step-by-step explanation:

first, find how much 1 chicken wings cost

$39.1 / 23= $1.70 (1 chicken wings cost = $1.70)

32.30/ 1.70 = 19

She bought 19 chicken wings

Hope it helps

If my answer helps you, please give me a brainliest! thanks.

If Aaliyah spent $32.30, she brought 19 chicken wings.

One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.

Aaliyah bought 23 chicken wings for $39.10.

Hence, as the price of each chicken wings is same, the price of each  chicken wings  will be=  $39.10÷23 = $ 1.70

She spent $32.30 in buying chicken wings.

So,  The number of chicken wings, she got = $32.30/$1.70 = 19.

Hence,  if Aaliyah spent $32.30, she brought 19 chicken wings.

For problem 17a) your answer is: x=11.5 degrees

Step-by-step explanation:

1. Measure of angle BCA will be 180°-124°=46°

2. In triangle BCA, you now have two angles. 46 degrees, and 2x.

3. Measure of angle ABE is an exterior angle of triangle BCA

4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC

5. substitute!! 2x+46=6x

Step-by-step explanation:

"How many more" means to subtract the products, not add them. Also, do the multiplication first before you subtract.

The coordinates of M ⇒ (-6,0)

Substitution

Step-by-step explanation:

Subtitue x=3 into the second equation

y=2(3)+1

y=6+1

y=7

Answer:

principal (p) = 2400

Amount (A) =2646

time (t) = 2 years

Interest = A-p

           =2646-2400=246

T = I * 100/(P*T)

  = 246*100/(2400 *2) = 5.125%

Step-by-step explanation:

The rate of interest will be 5.125% for the given data.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

Given that the sum of rs 2400 compounded to rs 2646 in 2 years. The compound interest will be calculated as,

principal (p) = 2400

Amount (A) =2646

time (t) = 2 years

Interest = A-p

=2646-2400=246

T = I x  100/(P x T)

T = ( 246 x 100) / (2400  x 2)

T = 5.125%

Hence, the interest rate will be %5.125.

Answer:

The measure of x = 45 degrees

Answer:

x is equal to 50.

Explanation:

The three lines intersect creating a triangle. All angle measures for triangles in Euclidean geometry must have a sum of 180 degrees. Because of the Vertical angles theorem, which states if two angles are opposite they are congruent, this means the angle across from 40 degrees is also 40 degrees. Since we know that the second angle is 90 degrees based on the right angle sign. By adding 40 and 90 you get a sum of 130. Now you subtract 130 from 180. This gives you 50 degrees. Since the Vertical angle theorem states two opposite angles are congruent we know the x is equal to 50 degrees.

Answer:

304

Step-by-step explanation:

4x76=304 mark as brainlist.

ok so 68 customers everything morning times 7 days per week is 476 customer.

now we know that 476 x .67 = $318.92

she make 8.50 per week plus $318.92 from customers

now we have this equation of

500 = 8.5x + 318.92

find x you will know how many weeks she needs.

8.5x = 500 - 318.92

8.5x = 181.08

x = 181.08/ 8.5

x ~~ 21.3 weeks

Answer:

1o weeks

Step-by-step explanation:

As I understand it she get's paid 8.50 per week

8.50x

and 0.67 per customer per week

0.67(68)x since there are 68 customers

it has to be at least 500

[tex]8.5x+0.67(68)x\geq 500\\\\8.5x+45.56x\geq 500\\\\56.06x\geq500\\\\x\geq\frac{500}{56.06} \\\\x\geq 9.24...\\\\x=10[/tex]

Explanation:

We're given that f(x) = x^2

The function g(x) is vertically stretched to be five times taller. We see this with the point (1,5) on the purple graph since its counterpart is at (1,1) on the blue graph.

We look at how the y values changed. So we had gone from y = 1 to y = 5. This jump means "multiply by 5"

If we do this to all the y values on the blue graph, then all the points jump to a height 5 times taller. Something like (2,4) moves to (2,20). Something like (3,9) goes to (3,45). And so on. This is what produces the purple g(x) graph.

You could say that

g(x) = 5*f(x)

g(x) = 5x^2

This works because y = f(x), so when we say 5*f(x), we really mean 5*y.
