If 39 = (1 3/10)b, we could simplify this by writing 39 - (13/10)b.

Solve this for b by mult. both terms by (10/13):

(10*39)
----------- = (10/13)(13/10)b.  Then b = 30 (answer)
      13

If you need an equation it is -3.4x=21.5

You simply divide both sides by -3.4 to get x=-6.32



if that's not right then just get on a calculator and calculate by doing what I said to divide

What is the solution to the system of equations below?
kifflom [539]

Answer:

(-5,-14)

Step-by-step explanation:

To find the solution of the system of two equations

\left\{\begin{array}{l}y=4x+6\\y=2x-4\end{array}\right.

equate right sides of these two equations:

4x+6=2x-4

Rewrite terms with x into the left side and without x into the right side:

4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5

Substitute x=-5 into the first equation:

y=4\cdot (-5)+6=-20+6=-14

The solution is (-5,-14)

Answer:

BC = 60

Step-by-step explanation:

3X + X = 80      <---- X = BC

3X + X = 4X

4X = 80   <---- DIVIDE BOTH SIDES BY 4

4X ÷ 4 = X

80 ÷ 4 = 20

20 × 3 = 60
