look at the photo I have sent

Basically...

4n - 8 = 14n + 12

Simply collect like terms,

4n-14n=12+8

-10n=20

Divide both sides by -10

n= -2

Please mark BRAINLIEST.

Step-by-step explanation:

[tex]4n - 8 = 14n - 4n \ \\ - 8 - 4 = 14n - 4n \\ - 20 = 10n \\ - \frac{20}{10} = n \\ n = - 2[/tex]

Answer:

[tex]4 - 2y = -2x [/tex]

subtract the 4 from one side

[tex] - 2y = - 2x - 4[/tex]

divide the -2 from the y and the-2x and 4

[tex]y = - x + 2[/tex]

-y + 6 = x

subtract the 6 and add -6 after the x

[tex] - y = x - 6[/tex]

6x - y - 3 = 0

add the y so it cancels out

y = 6x - 3

3y + 15x = -15

subtract the 15x

3y = -15x - 15

divide the 3

y = -5x -5

Answer:

true

Step-by-step explanation:

False, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.

Given that,
To justify the given statement is false or true.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
let the salary be x,
Salary after 5% raise = 1.05x
Salary after cut of 5% = [1 - 0.05] [1.05x]
Salary after a cut of 5% = 0.9975x
So the salary becomes 99.75% of the original salary x.

Thus, the given statement is false, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.

Answer:

E

Step-by-step explanation:

The sum of the 3 angles in Δ PQT = 180°

Subtract the sum of the 2 given angles from 180° for ∠ PQT

∠ PQT = 180° - (45 + 75)° = 180° - 120° = 60°

The opposite angles in a parallelogram are congruent , then

∠ QRS = ∠ PQT = 60° → E

Answer:

frist parentheses then subtract

The solution of equation  2(2x+3)-2 = 52(2x+3)−2 = 5 is x = -29/20.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

The given equation:

2(2x+3)-2 = 52(2x+3)−2 = 5

Simplifying,

2(2x+3)-2 = 52(2x+3)−2 - 5

Using PEMDAS,

first, we solve the parentheses

4x+6 - 2 = 104x + 156 - 2 - 5

4x+4 = 104x + 149

104x - 4x = 4 - 149

100x = -145

x = -145/100

x = -29/20

Therefore, the value of x is  -29/20.

Step-by-step explanation:

They're usually congruent for these type of angles. Also, y would be 50

Answer:

x = 50°

Step-by-step explanation:

y = 65° because the base angles of an isosceles triangle are equal

x = 50° because angles in a triangle add up 180°

Answer

For any two consecutive odd numbers, the difference is 2. For example, 3 and 5 are two consecutive odd numbers, their difference = 5 - 3 = 2. For any two consecutive even numbers, the difference is 2. For example, 6 and 8 are two consecutive even numbers, their difference = 8 - 6 = 2.

Answer:

A:B:C = 5:8:6

Step-by-step explanation:

You don't have to change A, you only have to change B and C in the second ratio given. First, B is 8 and secondly, B is 4. You can multiply 4 in the second ratio and make it 8, but, remember, always do the same change to the other side too. So, if you change the 4 to 8 by multiplying by 2, multiply 3, which is C, by 2 too. Then, you get B:C as 8:6. Lastly, you get the final answer as 5:8:6.

Answer:

[tex]A = 336[/tex] [tex]m^{2}[/tex]
