Step-by-step explanation:
BC = AD (opposite sides in parallelogram is equal)
x + 8 = 2x + 1
8 - 1 = 2x - x
7 = x
x = 7
BC = x + 8 = 7 + 8 = 15
Let the 1st number be x; 2nd number be y; 3rd number be z.
x + y + z = 79
x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first
Therefor,
x + (x * 5) + (x+16) = 79
1st step, multiply the 2nd number: x * 5 = 5x
x + 5x + x + 16 = 79
Add all like numbers:
7x + 16 = 79
To get x, transfer 16 to the other side and change its sign from positive to negative.
7x = 79 - 16
7x = 63
To get x, divide both sides by 7
7x/7 = 63/7
x = 9
To check. Substitute x by 9.
x + (x * 5) + (x+16) = 79
9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
Answer:
$3,062.50 after 5 years.
Step-by-step explanation:
The answer is 3,062.50 because 4.5% of 2,500 is 112.5 and 112.5 multiplied by 5 is 562.5 and 2,500 plus 562.5 is 3,062.50.
P.S Can I have brainliest?
Steps:
Question 1:
Step 1: Multiply both sides by h+0.5.
Step 2: Factor out variable f.
Step 3: Divide both sides by h^2+0.5h.
Question 2
Let's solve for g.
Step 1: Divide both sides by h.
Answers:
1: f=45h+42.5/h²+0.5h
2: g=16.5h+53.25/h

Answer:
C. 25%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased time, 75 minutes, and the old number is the original time, 60 minutes.
percent change = (75 min - 60 min)/(60 min) * 100%
percent change = (15 min)/(60 min) * 100%
percent change = 0.25 * 100%
percent change = 25%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 25%.
Answer: C. 25%
