If one piece of furniture was sold every 3/4 hour, how many pieces of furniture are sold in 3 hours

aleksklad [387]

Answer:

Two pieces of furniture.

Step-by-step explanation:

3 hours times 1 piece of furniture every 3/4 hours:

3 · $\frac{3}{4}$ = $\frac{3*3}{4}$ = $\frac{9}{4}$ = 2.25

Assuming that pieces of furniture cannot be sold in parts, 2 whole pieces of furniture will be sold in 3 hours.

Solve: 2 In 3 = In(x-4)

jeka57 [31]

Answer:

x = 13

Step-by-step explanation:

one of the rules of logarithm (for all bases, by the way, not just e for ln) is

$a \times ln(b) = ln( {b}^{a} )$

so, we have

ln(3²) = ln(x-4)

3² = x - 4

9 = x - 4

x = 13

Solve the simultaneous equation:<br>2x+3y=13<br><br>X+2y=9

Neko [114]

Answer:

2x + 3y = 13

4x - y = -2

In the second equation, subtract 4x from both sides.

-y = -2 - 4x

Divide both sides by -1.

y = 2 + 4x

Put this into the first equation in place of y.

2x + 3(2 + 4x) = 13

Multiply everything in the parenthesis by 3.

2x + 6 + 12x = 13

Combine like terms.

14x + 6 = 13

Subtract 6 from both sides.

14x = 7

Divide 14 on both sides.

x = 7 / 14

x = 0.5

Put this into the second equation in place of x.

4(0.5) - y = -2

2 - y = -2

Subtract 2 from both sides.

-y = -4

Divide both sides by -1.

y = 4

So x = 0.5 and y = 4.
