Answer:
Step-by-step explanation:
1) The sum of angles on a straight line is 180 degrees. Therefore
75 + a + 70 = 180
145 + a = 180
a = 180 - 145 = 35 degrees
2) Sum of the angles in a triangle is 180 degrees. Therefore,
a + b + 95 = 180
35 + b + 95 = 180
130 + b = 180
b = 180 - 130 = 50 degrees
3) c + 95 = 180 degrees (sum of angles on a straight line).
c = 180 - 95 = 85 degrees
4) 70 + c + d = 180 degrees
70 + 85 + d = 180
155 + d = 180
d = 180 - 155 = 25 degrees
5) e = 75 degrees
6) f + e + 75 = 180 degrees
f + 75 + 75 = 180
f + 150 = 180
f = 180 - 150 = 30 degrees
Answer:
y=-2x+6 and y=4x
Step-by-step explanation:
If you graph these two, the point where the two lines intersect is (1,4).
(9,-4) you have to plugin 9 to the equation in the form of x. Then you add 5 and that would be your y value
The total cost that will be paid by the family will be RM(15x - y).
<h3>How to calculate the cost?</h3>
The entrance fee to a circus for a child is RM(3x-y).
The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.
Therefore, the cost for 2 adults and three children will be:
= 2(3x + y) + 3(3x - y)
= 6x + 2y + 9x- 3y
= 15x - y
