Answer:

x=35

Step-by-step explanation:

The sum of angles in a triangle is equal to 180. In the triangle given, we have to add all the angles to find x.

So,

3x+x+40=180

to find x, we must isolate it:

combine common terms:

4x+40=180

subtract the 40 to both sides:

4x+40-40=180-40

divide by three to isolate the variable:

4x/4=140/4

and the resulting would be our x:

x=35

to check if our answers make sense, substitute.

3(35)+35+40=180

solve:

180=180

that's it! hope it helps :)

(3x²+3x+5)+(7x²-9x=8)=10x²-12x=13
Brilliant_brown [7]

The value of x is equal to -5/6

To solve this question, we have to add two polynomials together. The polynomials are;

  • 3x^2+3x+5
  • 7x^2-9x=8
<h3>Addition of Polynomials</h3>

This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.

In this given question, let's add the polynomials together.

(3x^2+3x+5) + (7x^2-9x = 8\)\\3x^2 + 7x^2 + 3x-9x+5-8 =10x^2-6x-3

Now, let's equate this with the last polynomial given

10x^2-6x-3=10x^2-12x-13\\10x^2-10x^2-6x+12x-3+13\\0+12x+10\\12x=-10

Let's solve for x

12x=-10\\x=-\frac{10}{12}\\x = -\frac{5}{6}

The value of x is equal to -5/6

A meat market sold five 7/5 pounds of meatballs on Monday six 1/2 pounds of meat balls on Tuesday and 4 pounds of meatballs on W
Whitepunk [10]

Answer:

Add all of them together. So your answer is

61/10 or 6 and

Step-by-step:

7/5 =1 and 2/5 or 14/10

1/2= 5/10

4/1 or 4= 40/10

14/10 + 5/10 + 40/10 = 61/10

Simplified: 6 and 1/10

The sum of 4 consecutive integers is 406. find the integers
BabaBlast [244]

Answer and Step-by-step explanation:

When trying to figure this out, we know that the numbers have to be one after the other, like 1, 2, 3, 4, or 55. 56, 57, 58. The last digit in the numbers also have to add to 6.

<u>The answer is:</u>

100 + 101 + 102 + 103

It adds up to 406, and the integers are consecutive.
