1/4
Step-by-step explanation:
Answer:
15 students celebrate both holidays
Step-by-step explanation:
Let the number of students that celebrate both be x
By set notation, we add up individual sides as follows to give the number of values on the universal set
Mathematically, that will be;
50 = (29-x) + (36-x) + x
50 = 29-x + 36-x + x
50 = 65-x
x = 65-50
x = 15
Answer:
f(-5)= 28
Step-by-step explanation:
The function is:
f(x)= x^2-2x-7
To find the answer put the value of -5 for all x's.
f(x)= x^2-2x-7
f(-5)=(-5)^2 - 2(-5)-7
f(-5)=25+10-7
f(-5)=35-7
f(-5)= 28 ...
There's an infinite number of equivalent fractions, but because this number can be simplified, simplification is probably your best answer. The simplified answer is 3/7, which you get by dividing both sides by 5. Other answers include 6/14, 9/21,12/28, and 30/35.
