Cross multiply
5(r+5) = 9(r-9)
5r + 25 = 9r - 81
25 = 4r - 81
4r = 106, r = 106/4 = 53/2
The answer is r = 53/2

The area of a trapezoid is 168cm2. The height is 16cm and the length of one of the parallel sides is 9cm. Find the length of the
dmitriy555 [2]

Answer:

12 cm

Step-by-step explanation:

The formula for the area of a trapezoid is written as:

1/2(b1 + b2)h

h = height = 16 cm

b1 = Length of one parallel side = 9cm

b2 = Length of second parallel side = ?

Area of trapezoid = 168cm²

The formula to find the length of the second parallel side =

b2 = 2A/h - b1

b2 = 2 × 168/16 - 9

b2 = 336/16 - 9

b2 = 21 - 9

b2 = 12cm

Therefore, the length of the second parallel side is 12 cm

92.96 as a fraction
nikklg [1K]
To change a decimal to a fraction you need to first place the decimal over 1. Next, for each number behind the decimal, you will multiply by a multiple of 10. Since there are 2 numbers behind the decimal, it's 100. Therefore, 
92.96 x 100 = 9296
1 x 100= 100


Your new fraction is 9296/100. Now we simplify it. I'm going by 2's so it may take a bit. 
Simplifying it twice by 2's your answer would be:

2324/25

if i have a line y=4x+7. I want to create another line that is perpendicular through point A (16,2). What is the new equation?
Charra [1.4K]
Perpendicular lines have the negative reciprocal slope, so the slope of your new line will be -1/4 and the current equation will be as follows:
y = -1/4x + b
(where b is the y intercept)

to find b, plug in point A and you'll get:
2 = -1/4(16) + b
2 = -4 + b
6 = b

the equation will be:
y = -1/4x + 6
