Answer:

The angles are 160 and 20 degrees respectively

Step-by-step explanation:

angles on a line sum to 180 degrees.

This tells us that (5x + 60) + (3x -40) = 180

we can expand brackets to give 8x + 20 = 180

8x = 160

x = 20 degrees

for the first equation (<span>Montell is 30 years)</span>:
x = y - 30
second equation ( in 5 years )

x + 5 = ( y + 5 ) ( 1/3)
solving the equation simultaneously

x = 10 years old

Answer:

(3, 3 )

Step-by-step explanation:

Under a translation < 8, 0 > then

A(- 5, - 3 ) → (- 5 + 8, - 3 + 0 ) → (3, - 3 )

The line with equation y = 0 is the x- axis

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

(3, - 3 ) → (3, 3 )
