Answer:
x = 63
Step-by-step explanation:
From the question, we can deduce the following points;
- 12 less than x which simply means 12 subtracted from x.
- the value of the above expression is equal to 51.
Translating the word problem into an algebraic expression, we have;
x - 12 = 51
Rearranging the equation (collecting like terms), we have;
x = 51 + 12
x = 63
So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles
each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles
51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush
1 set of paint brushes=$2.47
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:
here;
h = height of the building
F = mg = 15000g
g = 32 ft/s²
Therefore;
W = 9600000 joules
