I think the answer is 4 units
I think its 6\5 but ill dont know how to explain it..
Answer:
Step-by-step explanation:
Since the denominators are the same, we can just subtract 4 from 9 to get 5
The denominators should not be subtracted... they will remain the same
Now we take the result from 9-4 which equals 5
And we put that back into the equation so we have
This is not in simplest form. In order to get simplest form. Divide each number by two... so now we have
Which is the answer
1. Selena has to walk <em>to</em> school and <em>from </em>school.
That means that each day, she walks the distance from her house to the school twice.
If she walks 2/3 in a day, the distance must be half of that, or 1/3.
2. 3 batches = 3/4 cup.
Divide each side by 3.
1 batch = 1/4 cup.
3. 5 eighths minus 1 eighth = 4 eighths.
Since we have the same bottom number, we don't need to do anything special. This problem is just the same as something like <em>5 apples - 1 apple.</em>
4. First, let's convert 6 into thirds.
6 × 3 = 18
Therefore, 6 = 18/3.
Add 6 and 2/3.
18/3 + 2/3
20/3
5. To be a composite number, a number needs to be divisible by something besides 1 or itself.
Check your divisibility rules...
39 is divisible by 3 (39 ÷ 3 = 13), so this could be his house number.
6. 12 cupcakes - 9 chocolate = 3 vanilla.
3 vanilla cupcakes out of 12. (3/12)
We can simplify this fraction. 3 and 12 are both divisible by 3.
3/12 = 3÷3 / 12÷3 = 1/4
Answer:
B
Step-by-step explanation:
Since x is 2 wherever you see x put 2
solve x3 + x7+ 2
=(2)3 + (2)7 + 2
= you do the number outside the bracket multiplied by the number inside the bracket
like this
=(2 × 3) + (2 × 7) + 2
= 6+ 14 + 2
= 22
