Can someone please help me with math

Answer:

{1,4}

Step-by-step explanation:

A={3,6,9}

B={2,3,5,7}

C={1,2,3,4,5}

AUB={2,3,5,6,7,9}

(AUB)'={1,4,8,10}

(AUB)'⋂C={1,4}

Answer:

Step-by-step explanation:

A = {3 , 6 , 9}

B = {2,3,5,7}

A ∪ B = { 2,3,5,6,7,9}

(A∪B)' - is set of all elements in universal set  that are not in (A∪B)

(A∪B)'  = {1,4,8,10}

C = {1,2,3,4,5}

(A∪B)' ∩C = {1 , 4}

Answer:

2s-12=j

S+J=127

Step-by-step explanation:

ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j

. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127

hope this helps!!

step-by-step explanation

Number of subscriptions he must sell to earn $90 in one week is

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Fixed amount he earns per week = $15

Additional amount added depending on the number of subscription sold = $3

Let x be the number of subscription sold.

Amount earned in a week = 15 + 3x

If amount earned is $90,

15 + 3x = 90

3x = 75

x = 75 / 3 = 25

Hence the number of subscriptions is 25.

Answer:

Step-by-step explanation:

With a single application of the Law of Cosines, you can only find one of an unknown side or an unknown angle. The other three elements in the 4-variable equation must be specified.

However, a single application of the LoC can be used to find DE. Then, knowing the three sides, either of the unknown angles can be found from an additional application of the LoC.

So, the answer is "it depends." It is yes to all if finding DE first is allowed. It is "no" to the angles if they must be found without finding DE first.

Answer:

3

Step-by-step explanation:

To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values using two given points. I will use the first and last points.

(1, -2) & (13, 34)

(34 - (-2)) / (13 - 1)

Simplify the parentheses.

= (34 + 2) / (12)

= 36/12

Simplify the fraction.

36/12

= 3

This is your slope.

Answer:

x = 3

Step-by-step explanation:

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.

Answer:

Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

Answer:

4

Step-by-step explanation:

two-thirds = 2/3 (it's easier to write it out in number format)

2/3 = 4/6

So, there are 4 sixths in two-thirds.

Answer:

4 sixths

Step-by-step explanation:

Answer:

1. x^2 + 3x - 4 =0

x^2 + 3x = 4

x + 3x = √4

4x = 2

x =2/4

x = 1/4

2. 2x^2 - 4x - 3 = 0

2x^2 - 4x = 3

2x^2 - x = 3/4

2x - x = √3/4

x = √3/4

3.x(x-2) = 4

x^2 - 2x = 4

x - 2x = √4

- x = 2

x = -2

Answer:

Average grade now = 7.524

Step-by-step explanation:

Given - If the average score of the 20 students is 7.5. Then a student follows the test and gets a grade of 8.

To find - What is your average grade now?

Proof -

Given that,

Average score of 20 students = 7.5

So,

Total value of students = 20 × 7.5 = 150

Now,

Given that, One person added ang his grade is 8

So,

So Total value of 21 students = 150 + 8 = 158

Now,

Average score of 21 students = [tex]\frac{158}{21}[/tex] = 7.5238

∴ we get

Average grade now = 7.524
