Omg need help asap, the ones who helped me thank u so much

angle 1 = 20; angle 2 = 160

Step-by-step explanation:

(x-12) + 5x = 180

6x-12 = 180 (add 12 to each side)

6x = 192 (divide each side by 6 to get x by itself)

x = 32

plug x into each equation

angle 1: 32-12=20; 20

angle 2: 32x5= 160; 160

Angle 1: 20

Angle 2: 160

Step-by-step explanation:

Angles 1 and 2 both add up to 180 degrees assuming that line is a straight line. Since we are given a system of equations for both angles, we can add them together, let them equal 180, and use the answder to plug them into respective equations to find the angle amount.

(x-12)+5x=180   (adding both of the angles together)

6x-12=180         (combine x)

6x=192

x=32                  (isolate x)

Since we now know what x stands for, we can plug this number in to angle 1's equation (x-12) to find that angle.

32-12=20         (m<1's angles)

We can do this for angle 2 as well.

5(32)=160         (m<2's angle)

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
