Answer:
<u>The answer is -4 3/5</u>
Step-by-step explanation:
Let's reduce to its simplest form:
-3/5 + (-8/2) =
Step 1: Lowest Common Denominator (10):
- 6/10 + (-40/10) =
Step 2: Solve the parentheses:
- 6/10 - 40/10 =
Step 3: Subtract the fractions:
-46/10
Step 4: Simplify (Dividing by 2):
-23/5
Step 5: Converting the fraction to mixed number:
-4 3/5
<u>The answer is -4 3/5</u>
-5x(x+3)-7(x-3)/x^2-9= -5x^2-15x-7x+21/x^2-9= -5x^2-22x+21/x62-9
Step-by-step explanation:
as in the other problem, the table describes mutually exclusive attributes.
so, we can simply sum the numbers up to get the total number of students :
3+9+2+16 = 30 students.
so, when picking a random student, we have 30 possibilities.
now, how many of those 30 have the desired attributes (to have a brother AND a sister) ?
I see 3 in the table.
so, the probability to pick a student that has a brother and a sister is
3/30 = 1/10 = 0.1
First we will subtract $2 from $3.2 since that is late fee to get $1.2.
Now we divide $1.2 by $0.15 to get number of cents hence 8 days.
The answer is Maria is 8 days too late to hand over the book.
Hope this helps.
