#14. 1/11
#15. Associative property of multiplication
Hope it helps
Let's solve for x.
x
+
4
y
=
(
14
)
(
3
)
x
+
7
y
Step 1: Add -42x to both sides.
x
+
4
y
+
−
42
x
=
42
x
+
7
y
+
−
42
x
−
41
x
+
4
y
=
7
y
Step 2: Add -4y to both sides.
−
41
x
+
4
y

−
4
y
=
7
y

y
−
41
x
=
3
y
Step 3: Divide both sides by -41.
−

No, Kira's reasoning is not correct, the correct answer is 3 1/2
Steps To Solve
1. subtract 61/4 - 2 3/4
2. Since you cannot subtract you add the denominator to the numerator
3. leave the denominator the same
4. once you do that decrease the whole number by one
5. your answer should be 3 1/2

<u>Given</u><u> </u><u>:</u>
- White balls = 5
- Red balls = 8
- Yellow balls = 7
- Green balls = 4
<u>Answer</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 4 green balls. Therefore,
- P (E) = 4 / 24
- P (E) = 2 / 12
- P (E) = 1 / 6
<u>Answer</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 8 red balls. Therefore,
- P (E) = 8 / 24
- P (E) = 4 / 12
- P (E) = 2 / 6
- P (E) = 1 / 3
<u>Answer</u><u> </u><u>3</u><u> </u><u>:</u><u>-</u>
We know that,
- P (E) = No. of favourable outcomes / Total number of outcomes.
>> Total no. of outcomes = 5 + 8 + 7 + 4
>> Total no. of outcomes = 24
As there are 15 balls that are neither green nor white. (Red balls+ yellow balls)
- P (E) = 15 / 24
- P (E) = 5 / 8
