<span>Taliba has $31 to order phone cases online.
Each phone case costs $7, and there is a $4 shipping charge.
How many phone cases, x, can Taliba buy?
^^^ that is the situation that does NOT represent the equation </span>
Phil will have 36 rocks, and since Phil has 3x more than Peter, you take 36/3 which equals 12, 12+36=48. then to find the difference you take 36-12 which equals 24
As a tip, remember that whenever a problem says "of," multiply. So if you want to find brown hair and long hair, multiply, 4/5*3/4.
4/5*3/4=12/20=3/5
Part A: 3/5 of the girls in the fifth grade class have long brown hair.
If they have long brown hair and green eyes, multiply 3/5*1/3. Since it is all three, get the answer from above and multiply it by 1/3.
3/5*1/3=3/15=1/5
Part B: 1/4 of the girls in the fifth grade class have long brown hair and green eyes.
Hope this helps! If you have any questions, just ask!
Answer:
The correct options are the first and the fourth
and
Step-by-step explanation:
We can observe in the graph that when x = 0 then y = 3. Therefore f(0) must be equal to 3.
We also observe in the graph that f(x) = 0 when x = 3+12k, {3, 15, 27...}
where k is a Whole number k : {0, 1, 3, 4, 5....n}
The function that meets these two conditions is
and
We can check it by substituting x = 3+12k and verifying that f(x) = 0
We know that and
Then
Also
We know that and
Therefore The correct options are the first and the fourth
