Answer: She has to score a minimum of 92 marks to take her average to 80
Step-by-step explanation:
Let the equation be
Three months total = 76 x 3 = 228
(x + 228) / 4 = 80
x + 228 = 80 x 4
x = 320 - 228
x = 92
5(4x-5y)-2=453
5(4x-5y)=455
4x-5y=91
When solving for x
4x=5y+91
x= 5y+91/4
When solving for y
-5y=-4x+91
y=-4x+91/-5

Answer:
(4, 3 ) and (4, - 3 )
Step-by-step explanation:
A distance of 5 units from the origin represents the hypotenuse of a right triangle with sides 3- 4 - 5
If the x-coordinate is 4 then the y-coordinate is | 3 | = ± 3
the coordinates are (4, 3 ) and (4, - 3 )
