Answer:
E. -8, -29
Step-by-step explanation:
a-b=21
5a -2b =18
Take the first equation and solve for a by adding b to each side
a-b=21
a-b+b=21+b
a = 21+b
Now substitute a=21+b into the second equation
5a -2b =18
5(21+b) -2b =18
Distribute the 5
105 +5b-2b =18
Combine like terms
105 +3b =18
Subtract 105 from each side
105-105 +3b = 18-105
3b = -87
Divide each side by 3
3b/3 =-87/3
b = -29
if b = -29, we can substitute it into a =21+b
a = 21-29
a = -8
Answer:
420 inches or 35 feet of trim is needed for 5 desks.
Step-by-step explanation:
We know that one desk requires 84 inches, so we need to find out how many inches are needed for 5 desk.
If we know one desk needs 84 inches then we have 1 desk = 84 inches.
To get 5 desk, we need to multiply both sides by 5.
1 desk = 84 inches. (multiply by 5 for both sides)
5 desks = 84 * 5
5 desks = 420 inches
We know now that 5 desks require 420 inches, but many people use feet instead.
There are 12 inches in 1 foot, so we need to divide 420 inches by 12 inches to get how many feet we need.
420/12 = 35 feet.
Hope this helps!
So assuming pi represents 1 term or the ratio of the diameter to the circumfernce and B5 means B times 5 and not B^5
65pi=B5
divide both sides by 5
(65pi)/5=B
simplify
13pi=B
