Answer:
74/100 OR 37/50
Step-by-step explanation:
First add everyone together since its asking for no cold / everyone.
41 + 15 + 12 + 5 + 21 + 6 = 100
Then add to gether the total of people without a cold.
41 + 12 + 21 = 74
Next you just put the ratio in order which in this case would be no cold / everyone then if possible simplify.
74/100 = 37/50
Answer:
Step-by-step explanation:
-3x + 4y = -20
y = x - 4
Put the second equation into the first equation in place of y.
-3x + 4 (x - 4) = -20
Multiply everything in the parenthesis by 4.
-3x + 4x - 16 = -20
Combine like terms.
x - 16 = -20
Add 16 to both sides.
x = -4
Put this into the second equation in place of x.
y = -4 - 4
y = -8
Your solution set is (-4,-8).
Hope this helps!
