Answer:

21

Step-by-step explanation:

I'll represent semi perimeter as s

What we know:

s-A=8

s-B=7

s-C=6

A+B+C=2s

we can substitute all the sides in the equation

s-A=8

s-8-A=0

s-8=A

Do this for B and C

A+B+C=2s

(s-8)+(s-7)+(s-6)=2s

3s-21=2s

-21=-s

s=21

Is 3/x+4/y=2 linear or non-linear
Eduardwww [97]

The given equation is non-linear.

Solution:

Given expression is \frac{3}{x} +\frac{4}{y} =2.

To find the equation is linear or non-linear.

Linear equation is a straight line which is in the form ax + by + c = 0.

Otherwise it is non-linear equation.

⇒ \frac{3}{x} +\frac{4}{y} =2

Do cross multiply for the fractions to make the denominators same.

⇒ \frac{3y}{yx} +\frac{4x}{yx} =2

⇒ \frac{3y+4x}{yx} =2

Do cross multiplication.

⇒ 3y+4x=2yx

⇒ 4x+3y-2yx=0

Here, there is no constant term.

So, the equation is not a straight line.

Hence, the given equation is non-linear.

Answer:

  • 3 big bucks
  • 6 little bucks
  • 17 does

Step-by-step explanation:

Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.

  B + L + D = 26 . . . . . . total bagged

  D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks

  B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks

__

We can substitute for B and D in the first equation:

  L/2 + L + (5 +2L) = 26

  7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms

  L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7

  D = 5 + 2·6 = 17

  B = 6/2 = 3

The party bagged 3 big bucks, 6 little bucks and 17 does.

velikii [3]
19 thousands is 19 x 1000 = 19,000 
7 tens is 7 x 10 = 70

19 thousands plus 7 tens is 19,000 + 70 which is 19,070.
