A number, n, increased by 6, and them the sum is doubled

Answer:

x=-5 y=2

Step-by-step explanation:

1) multiplying equation 1 by 4 and multiplying equation 2 by 2 .

2)adding them we get value of y.

3) replacing value of y in either of given equation

Answer:

The property is the neutral element, in this case, it's the 0

The equation is justified using the additive inverse property of real numbers. The equation [tex]\(x + (37 + (-37)) = x + 0\)[/tex] is justified by the additive inverse property of real numbers.

According to the additive inverse property, for any real number a, there exists another real number -a such that their sum is equal to zero:

[tex]\(a + (-a) = 0\)[/tex]

In the given equation, 37 and -37 are additive inverses of each other, meaning [tex]\(37 + (-37) = 0\).[/tex] Therefore, the equation simplifies to:

[tex]\(x + (37 + (-37)) = x + 0\)\(x + 0 = x\)[/tex]

So, the equation is justified using the additive inverse property of real numbers.

Step-by-step explanation:

Prime numbers are numbers that have two factors thus 1 and the number itself . Example; 2 ,3,5 ,7 and 11

Also 0 and 1 is not a prime number

Answer:

C. [tex]\displaystyle 3[/tex]

Step-by-step explanation:

Prime Numbers consist of two factours -- 1 and that number. Just so you know, you can AUTOMATICALLY eliminate the first two choises because those two numbers are not composite nor prime. Now, I can predict that your next lesson will probably be about prime factorisation, in which you have to find the prime factorisation of numbers, using two methods:

3 3|3

| ⁻⁻

3 1

Factour Tree Ladder Diagram

9 3|9

/\ ⁻⁻

3 3 3|3

So, the prime factorisation of 9 is [tex]\displaystyle 3^2,[/tex]and the prime factorisation of 3 is 3.

Hi! I'm happy to help!

To first solve this, we need to make those mixed numbers improper fractions.

To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.

[tex]\frac{9}{2}[/tex]​ ÷(−1[tex]\frac{3}{7}[/tex]​ )

Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.

[tex]\frac{9}{2}[/tex]​ ÷(−[tex]\frac{10}{7}[/tex]​ )

From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.

[tex]\frac{9}{2}[/tex]​ ×(−[tex]\frac{7}{10}[/tex]​ )

Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)

-[tex]\frac{63}{20}[/tex]

Since we cannot simplify, our final answer is -63/20.

Answer:

b = 30

Step-by-step explanation:

b - 1 + 8 = 37       (Given)

b + 7 = 37            (Simplify)

b + 7 - 7 = 37 - 7  (Subtract 7 on both sides)

b = 30                  (Simplify)

Answer:

Kamille paid $34.88 for her outfit after tax.

Ms. Roth will pay $59.16 in total.

Step-by-step explanation:

Kamille brought a new outfit that cost $32.00. The tax rate is 9%. How much did she pay for the outfit after tax?

32.00 x 0.09 = 2.88

32 + 2.88 = 34.88

Ms. Roth went to I-Hop for breakfast. She ordered pancakes for $5.00, eggs for $3.50, and orange juice for 42.50. if she tips the waiter 16%, how much will she pay in total?

5 + 3.5 + 42.50 = 51

51 x 0.16 = 8.16

51 + 8.16 = 59.16

Answer:

Substitute what t and n equals to in the equation and just solve using algebra.

So number 2, plug in -3 where ever the variable N is located in and solve.

g(-3) = 3(-3)^2+3+2(-3)  ---> g(-3) = 27+3-6 ---> g(-3) = 24 That's the answer for 2.

For 1

plug in -5 into the t variable and solve.

k(t) = -2 |3(-5)| + 2 Since the || is between the 3 and 5, answer will be positive.

k(t) = -2(15)+2

k(t) = -28

Step-by-step explanation:

The answer 6x - 2y = 5

Step-by-step explanation:

The general formula of linear equations is y = mx + c

where m is the slope

so when we put this in the general form, it will be

-2y = -6x + 5

y = 3x - 5/2

and so the slope is 3

Answer:

a = 32

Step-by-step explanation:

This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths

68^2 = 60^2 + a^2

4624 = 3600 + a^2

4624 - 3600 = a^2

1024 = a^2 find the root for both sides

32 = a
