Problem 16 Begin by setting corresponding positions equal to each other.
9 = x + 2y and 13 = 4x + 1
The second equation only has one variable so you should solve it first.
13 = 4x + 1
13 - 1 = 4x + 1 - 1
12 = 4x (divide both sides by 4)
3 = x
you can use this value to find y in the other equation
9 = 3 + 2y
9 - 3 = 3 - 3 + 2y
6 = 2y
3 = y
Answer:
x= 40°
Step-by-step explanation:
since the angles of the quadrilateral add up to 360°
then to find the agle x:
step:1
add alll the angles given in the quadrilateral
100+120+100
= 320
step:2
now subtract the sum of the quadrilateral from the sum of alll angles
360°-320° = 40°
therefore the answer equates to 40°
We can see that John paints at a constant rate: therefore, the correct statement that describes this situation is that John likes to paint.
Haha got you, the correct answer is John paints 1 portrait every 4 hours.
