Solve the two-step equation. − 2 3 x – 21 4 = 27 4
svetoff [14.1K]

Answer:

Step-by-step explanation:

I'm going to assume that the problem is -23x -214 = 274

And in that case...

1. First isolate the x-value by adding 214 to both sides of the equation:

-23x = 488

2. Then, divide both sides by -23 to truly get x alone:

x = -\frac{488}{23} or -21.22

Answer:

2x +21

Step-by-step explanation:

log_{5} {5}^{(2x - 9)}   +  log_{3} {729}^{5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} {( {3}^{6} )}^{5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} { {3}}^{6 \times 5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} { {3}}^{30}    \\  \\ =(2x - 9)  log_{5} {5} + 30 log_{3} { {3}}   \\  \\  = (2x - 9).1 + 30(1 )\\ ( \because \: log_{a} { {a}}    = 1) \\  \\  = 2x - 9 + 30 \\  \\  = 2x +21

Solve for X<br> 1) 5<br> 2) 6<br> 3) 4<br> 4) 3
Molodets [167]

Answer:

x = 4

Step-by-step explanation:

given 2 chords intersecting inside a circle , then

the product of the parts of one chord is equal to the product of the parts of the other chord, that is

9 × 4x = 8(4x + 2)

36x = 32x + 16 ( subtract 32x from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

Population Growth The population of a town of 5000
Nesterboy [21]

Answer:

a) A=5000{(1.03)}^{t}

b) 5464 inhabitants.

Step-by-step explanation:

The formula used for compound interest becomes very helpful in this case.

A=P{(1+r)}^{t}\\\\When:\\A = Final Value\\P = Initial Value\\r = Rate of Change (Decimal)\\t = Time (Years)

Knowing this, we can easily calculate the value for any year, counting from the original 5000.

From this formula, we can derive a specific one that will serve for any value of <em>t</em>.

a)

A=5000{(1+0.03)}^{t}\\A=5000{(1.03)}^{t}

b) Apply the formula:

A=5000{(1.03)}^{3}\\A=5000(1.092727)\\A=5463.635=5464

The town will have 5464 inhabitants.
