Answer:
=> 18/156 = 3/26
Step-by-step explanation:
Answer:
A = 9p² - 25
Step-by-step explanation:
The side lengths were 3p. 5 was added to the length and subtracted from the width. This means that
l = 3p + 5
w = 3p - 5
Plug these values into the formula for the area of a rectangle.
A = lw
A = (3p + 5)(3p - 5)
A = 9p² - 25
The area of the rectangle is 9p² - 25.
∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°
Question a:
∠1 = 23°
∠2 = 90 - 23 = 67°
Ans: 67°
Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29
∠1 = 29°
∠2 = 2(29) + 3 = 61°
Ans: ∠1 = 29°, ∠2 = 61°
3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
Step-by-step explanation:
Total pages = 150
Pages per days = 3
Pages left to read = 60
Let,
x be the number of days.
According to given statement;
Total pages = Pages per day*number of days + Pages left to read

Dividing both sides by 3

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
