To clear the fractions we multiply both sides by the least common multiple of all the denominators.

1/2 x + 2/3 = 4

Denominators 2 and 3, so multiply both sides by [Answer]: 6

3/4 x + 1 = 5/6

Denoms 4 and 6, LCM=12 Answer: 12

6/7 x - 2/3 = 5/21

LCM(7,3,21)=21 Answer: 21

3/5 + x/2 = 9

LCM(5,2) Answer: 10

25/4 = 6 + 1/2 x

LCM(4,2) Answer: 4

A banner in the shape of an isosceles triangle is hung over the side of a building. The banner has a base of 30ft (at the roof),

Rashid [163]

Answer:

W = 9600000 joules

Step-by-step explanation:

From the given information:

The area of the banner = 1/2 × 30 × 20 = 300 ft²

The mass of the banner = 300 × 50 = 15000 pounds

Now; the integral for the required work is:

$W = \int^h_o F \ ds$

here;

h = height of the building

F = mg = 15000g

g = 32 ft/s²

Therefore;

$W = \int ^h_o 15000g \ ds$

$W = \int ^{20}_0 \ 15000 (32)(20)$

W = 9600000 joules
