5 solve for x
6 find the measurement for each angle below​

5. x = 18°

6. 5x = 50°, 4x= 40°

Step-by-step explanation:

5. Both the angles shown above add up to 180, due to them being supplementary, so you get the following equation:

6x + 4x = 180

which simplifies to

10x = 180

meaning x is equal to 18.

6. The angle measures of 5x and 4x add up to 90 because they are complementary angles, giving us the equation below:

5x + 4x = 90

simplifying to

9x = 90,

and resulting in

x = 10

So 5x is equal to 50 and 4x is equal to 40.

3x + 4y -25 =0 represents the amount of change sianna should recieve

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
