(7 ⋅ 40+20) ÷ 3–15+2 ⋅ (10 ⋅ 5) = Please give me the answer by today!
I literally need this as fast as possible.

6350

Step-by-step explanation:

I swear it is right.

7 * 60=420

420 / 3=140

140-15=125

125+2=127

127 * 50=6350

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
