Need help pls I don’t like math

Answer:

x= 7

Step-by-step explanation:

Theorem:  The sum of the angles of a triangle is 180

Memorize that theorem

8x - 9 + 63 + 70 = 180

8x + 124 = 180

8x = 56

x= 7

Answer:

13.7

Step-by-step explanation:

fill the numbers in using pythagorean theory

[tex]a^{2} + b^{2} = c^{2}[/tex]

(the hypotenuse has to be [tex]c^{2}[/tex])

[tex]9.2^{2} + b^{2} = 16.5^{2}[/tex]

[tex]84.64 + b^{2} = 272.25[/tex]

[tex]b^{2} = 187.61[/tex]

(to get [tex]b[/tex] alone you have to find the square root of both sides)

[tex]b = 13.69707[/tex]

round that and you get

[tex]b = 13.7[/tex]!

Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)

Answer:

B

Step-by-step explanation:

Pythagorean theorem:

6^2 + (4/2)^2 = x^2

36 + 4 = x^2

40 = x^2

x = [tex]\sqrt{40}[/tex]= [tex]2\sqrt{10}[/tex]

Answer:

Step-by-step explanation:

11). 6x + 3y = 9

    3(2x + y) = 9

    2x + y = 3

    y = -2x + 3

    Since variables are of single degree therefore, it's a linear function

12). 3y - 2x = -2x - 12

     3y - 2x + 2x = -2x - 12 + 2x

     3y = -12

      y = -4

     Since variable y is of single degree therefore its a linear function.

13). 11y + 4x = -8 + 11y

     11y + 4x - 11y = -8 + 11y - 11y

     4x = -8

      x = -2

      Linear function.

14). 4x - 3 + 2y = 8x - 9

     4x + 2y - 3 - 4x = 8x - 4x - 9

     2y - 3 = 4x - 9

     2y = 4x - 9 + 3

     2y = 4x - 6    

      y = 2x - 3

      Linear function.

Step-by-step explanation:

As we can see it is a parallelogram so here the diagonals bisect so

6y + 1 = 4y + 9

6y - 4y = 9 - 1

2y = 8

y = 8 / 2

y = 4

2x - 5 =x + 7

2x + x = 7 + 5

3x = 12

x = 12 / 3

x = 4

Answer: See explanation

Step-by-step explanation:

The number of comedy films will be:

= 6/(6+8+1) × 135

= 6/15 × 135

= 54 comedy films

The number of action films will be:

= 8/(6+8+1) × 135

= 8/15 × 135

= 72 action films

The number of horror films will be:

= 1/(6+8+1) × 135

= 1/15 × 135

= 9 horror films

Answer:

The first one is 0.6

The second one is -2.8

The third one is -3

Step-by-step explanation:

Have a nice day! :)

5/6 - 3/8

Rewrite the fractions to have a common denominator:

5/6 x 4 = 20/24

3/8 x 3 = 9/24

Now you have 20/24 - 9/24 = 11/24

The answer is D. 11/24

Answer:

D. 11/24

Answer:

6x^2-5x+1

Step-by-step explanation:

Use the foil method:

multiply 2x with 3x and -1.

then multiply -1 with 3x and -1

when multiplied, you should have gotten 2x×3x=6x^2, then 2x×-1, then -1×3x=-3x, then you put all of the answers in order from variables with exponents to normal variables to non variables

Answer:

3.9

Step-by-step explanation:

3.98371685

Answer:

No

Step-by-step explanation:

7 squared + 10 squared = 149

13 squared = 169

As you can see these two products are not equal. They have to be equal to be a right triangle.

So this triangle is not a right triangle.

Hope that helped you and have a great day!

Answer:

No it is not.

Step-by-step explanation:

Let h = 13, p = 10 and b =7

Using pythagoras theorem,

h² = p² + b²

13² = 10² + 7²

169 = 100 + 49

169 = 149

This is false so the triangle is not a right angled triangle.

Answer

[tex]\frac{573}{400}[/tex]

Answer:

[tex]Each =\pounds 1121[/tex]

Step-by-step explanation:

See comment for complete question.

Given

[tex]Total = \pounds 8968[/tex]

[tex]Projects = 8[/tex]

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

[tex]Each =\frac{Total}{Projects}[/tex]

[tex]Each =\frac{\pounds 8968}{8}[/tex]

[tex]Each =\pounds 1121[/tex]

Each project gets £1121

Answer:

I deposit $500 in my bank from my check this week. I have to withdraw $550 from my bank to pay my medical bills. I am short -55/55 dollars so I wait to pay my medical bills.

I owe $60 to my school for damage on a school laptop. I only have $5 so I am 55 dollars short.

I withdraw $2,000 from my bank to deposit $1950 a week later. I want to deposit the same amount of money I put last week. I am short 55 dollars.

Step-by-step explanation:

I put different scenarios because I didn't know if any of them were good enough.

To find what needs to be added subtract the two numbers:

19/21 - 11/21 = 8/21

You need to add 8/21 to 11/21 to get 19/21

If the perimeter is 3(2v-6)

Than

Pull out like factors : 2v - 6  =   2 • (v - 3)

Final result : 6 • (v - 3)

Given the result your answer would be 6.
