Answer:

x = 22

Step-by-step explanation:

line AD is 180°

so 40° + (5x + 30°) = 180°

solve for x.

5x = 180-30-40

5x= 110

x = 110/5

x= 22

Answer: 22

180 - 40 = 140

5(22) = 110

110 + 30 = 140

Ber [7]

-4x+4x +5y +6y = 17-6

11y=11

divide both side by 11 to isolate y

y=1

4x+6(1) = -6

subtract 6 on both sides

4x=-12

divide 4 on both sides

x=-3

Which equation accurately represents this statement? Select three options. Negative 3 less than 4. 9 times a number, x, is the s
Scilla [17]

The correct statements about the equation are b, c, and e.

\rm 4.9x-(-3)=12.8\\\\ 3+4.9x=12.8\\\\12.8=4.9x+3

<h3>Polynomial;</h3>

The highest power of the polynomial is called the degree of the polynomial.

We have to determine

Which equation accurately represents this statement?

Statement; Negative 3 less than 4.9 times a number, x, is the same as 12.8.

Then,

The equation accurately represents this statement is;

\rm 4.9x-(-3)=12.8\\\\4.9x+3=12.8\\\\4.9x=12.8-3\\\\4.9x=9.8\\\\x=\dfrac{9.8}{4.9}\\\\x=2

Hence, the correct statements about the equation are b, c, and e.
