If you mean fraction,
Tom: 2/3
Sam: 1/4
Now we change the denominator.
Tom: 6/12
Sam: 3/12
6/12 + 3/12 = 9/12
9/12 can be simplified, so 3/4 of the pie was eaten.
4/4 - 3/4 = 1/4
The answer is 1/4.
Answer:
C
Step-by-step explanation:
First, write 4 ½ in improper form. 2 × 4 + 1 = 9. So the fraction is 9/2.
Now divide:
9/2 ÷ 1/3
To divide by a fraction, multiply by the reciprocal:
9/2 × 3/1
27/2
13 1/2
Answer C.
Inverse variation:
k is a constant
Use the given information (when x=4 y=4) to find the value of the constant:
Then, the given relationship has the next equation:
Use the equation above to find y when x=2:
Then, when x=2, y=8
The answer is A uhhhhhhhhhhhhhhh
Answer:
r = 4
Step-by-step explanation:
You need to use the slope formula to solve for r.
1. Write out the equation using slope formula
(-7 - 1)/(r + 4) = -1
2. Multiply both sides by r + 4
-8 = -r - 4
3. Add 4 on both sides. Optionally, use the reflexive property of equality.
-r = -4
4. Multiply both sides by -1
r = 4
