Answer:
There is a total of 45 members in the math club.
Step-by-step explanation:
What I did is I multiplied 9 by 5 and got 45. I multiplied 9 by 5 because the question stated that 9 students are 20%. 20% times 5 would be 100%, which would be the total number of students.
Hope this helped :)
It equals 1/2. when dividing by a fraction you get the reciprocal of the second on which is 2/3 would now be 3/2 and you multiply it by 1/3. and get 1/2
Hi,
The answer would be D. Here's why.
You could just do trial and error or like an equation but to make it simple, use trial and error since it is only small number.
If x was 5 and y was -4, just replace them into the equations...
4x+y=16. if x=5 and y=-4, then the equation would be 4*5 +(-4)=16 then it would be 20-4=16. 16=16. There first equation solved. Now lets do the next one. 2x+3y=-2. If x=5 and y=-4, then the equation would 2*5+3*(-4)=-2. Simplify and you get 10+(-12)= -2. 10-12=-2. -2=-2
This is why the answer is D (5, -4)
Hope this helps!
The opposite of -25
to find the opposite of a number, just switch the sign
example : opposite of 3 is -3
opposite of -5 is 5
so the opposite of -25 is 25 <==
