Discriminant = b^2 - 4ac
= 1^2 - 4*1*2
= -7

James earned $816 each year. He earned x dollars less per month than Matt, who earned $80 per month. Equation: 12(80 – x) = 816

Nataly_w [17]

Answer:

see below

Step-by-step explanation:

12(80 – x) = 816

Divide each side by 12

80-x = 816 /12

80-x = 68

Subtract 80 from each side

80-x-80 = 68-80

-x = -12

Multiply each side by -1

x = 12

James earned 80-12 = 68

Help no good at maths

We know that all angles of a triangle equal 180 when added together. We have two angle measures which are 3/2x and 1/2x
***3/2x + 1/2x + x = 180 degrees***
For the other way you can switch around the positions of the angles in the equation as long as the = stays 180 so like
X + 3/2x + 1/2x = 180
180 + x + 1/2x + 3/2x
Or maybe change the 3/2x to 1 1/2x
