Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5
There were 5000 mangoes in the basket, 3750 of them were good.
% mangoes
25% ---------- 1250
75% ----------- X
25x = 1250.75
25x = 93750
X = 93750/25
X = 3750 mangoes
3750+1250 = 5000
A & X = 45 degrees
C & Z= 60 degrees
There is 180 degrees in a triangle.
A+C=105 degrees
180-105=75
B = Y
Y=75 degrees
