the sum of the expanded angle is 180⇒

40+40+2x+30=180\\2x=70\\x=35

Answer:

x=35

Step-by-step explanation:

Add the 2 known angles: 80°

Then subtract them from eight since a straight line is 180°: 180-80= 100

then you have the equation: 2x+30=100

2x+30=100

     -30  -30

      2x=70

       \frac{2x}{2} =\frac{70}{2}

        x=35

Select the statement that describes this expression: 5 x 3 − (2 x 4) + 5.
Mashcka [7]

Answer:

It would be subtract the product of 2 and 4 from the product of 5 and 3, then add 5 because it’s parenthesis then you would multiply/devide then add/subtract whatever comes first

Step-by-step explanation:

5x3 - (2x4) + 5

5x3 - 8 + 5

15 - 8 + 5

7 + 5

The sum of two numbers is 25 one number is five less than the other number find the larger number
prohojiy [21]

*NOT MY WORK ITS FROM SOMEONE ELSE WHO ASKED THE SAME PROBLEM*

Answer: x=15, y= 10

Step-by-step explanation:

Answer: x=15, y=10

*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.

Step-by-step explanation:

For this problem, we can use system of equations. Let's use x for one number and y for the other.

First Equation:

x+y=25

We get this equation because it states that the sum of the two numbers is 25.

Second Equation:

y=x-5

We get this equation because it says one number (y) is 5 less than the other (x).

Since we have two equations, we can use substitution method to solve.

                                 [distribute 1 to (x-5)]

                                    [combine like terms]

                                        [add both sides by 5]

                                               [divide both sides by 2]

Now that we have x, we can plug it into any of the equations to find y.

                                         [plug in x=15]

                                        [subtract both sides by 15]

Finally, we have our answer, x=15 and y=10.
