Answer:
Step-by-step explanation:
To evaluate :
Solution:
Two negatives multiply to become a positive.
Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.
⇒ 
Since the denominators are same for both fractions, so we simply add the numerators.
⇒ 
⇒ 
(Answer)
#3). $124.16 will be in amount of deposit
#4) new balance, b = original balance + deposits - payments
=》 b =$782.14+$124.16 - ($450+$58.25)
=》 b = $398.05
Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number. ... Step 1: Find the Lowest Common Multiple (LCM) between the denominators.
7/4 5/6
7+5=
7/5
1 2/5
D=dimes
q=quarters
d + q = 20
.10d + .25q = 3.05
d=-q + 20
.10(-q + 20) +.25q = 3.05
-.10q + 2 + .25 = 3.05
.15q + 2 = 3.05
.15q + 2 - 2 = 3.05 - 2
.15q = 1.05
.15q/.15 = 1.05/.15
q = 7
d + 7 = 20
d + 7 - 7 = 20 - 7
d = 13
Sally has 7 quarters and 13 dimes.

Answer:
=9.4
Step-by-step explanation:
The median is the middle of the numbers when lined up from smallest to largest
(n, n+5, n+6, n+9, n+15)
The median is n+6
n+6 = 9
Subtract 6 from each side
n +6-6 = 9-6
n = 3
The numbers are
(n, n+5, n+6, n+9, n+15)
3, 8 ,9 ,12, 15
The mean is where you add up all the numbers and divide by the number of numbers
mean = (3+8+9+12+15) /5
= (47)/5
= 9 2/5
=9.4
