4×[x-y=1] 4x-4y=4
3x+4y+4x-4y=5+4
7x=9 x=9/7
9/7-y=1 y=9/7-1 y=2/7
Answer:
18/25
Step-by-step explanation:
Total number of students = 23+14+10+3 = 50.
14 out of 50 are playing sport and taking a foreign language.
So the answer is (50 - 14) / 50
= 36/50
= 18/25.
y < 1 - 3x
Because y is less than that function, we need to find all the values shaded below the line. This gets rid of the left two answers.
Because we're using the < symbol and not the ≤ symbol, we don't include the line. We're looking for all the values EXCEPT the ones that are equal to the equation and above.
So the answer is the bottom right
20% = 1/5
0.35 = 35/100 but simplified is 7/20
