Mathematics
1 answer:
Zigmanuir [339]2 years ago

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

  • (\frac{2}{3}s + \frac{5}{6}s) = 21
  • (\frac{4}{6}s + \frac{5}{6}s) = 21
  • \frac{9}{6}s = 21
  • \frac{3}{2}s=21

Step 2: Multiply both sides by 2/3.

  • \frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}
  • s = \frac{42}{3}
  • s = 14

Please can someone help?

Hey there! :)

Answer:

(5, -2), or x = 5 and y = -2.

Step-by-step explanation:

We can solve the two equations algebraically by eliminating a variable:

2x + 5y = 0

3x - 4y = 23

Eliminate the x variable by finding the least common multiple and multiplying both equations:

3(2x + 5y = 0)

2(3x - 4y = 23)

Distribute and subtract the bottom equation from the top:

6x + 15y = 0

6x - 8y = 46

------------------

0x + 23y = -46

23y = -46

y = -2.

Plug in y into an equation to solve for x:

2x + 5(-2) = 0

2x - 10 = 0

2x = 10

x = 5. Therefore:

The solution to this equation is (5, -2), or x = 5 and y = -2.

Which equation is the equivalent form of 20(3)^5x = 820?
makvit [3.9K]

Answer:

x=ln(41)/ln(243)

Step-by-step explanation:

20(3)^5x=820

3^5x=820/20

3^5x=41

5x=ln(41)/ln(3)

x=(1/5)[ln(41)/ln(3)]

x=ln(41)/ln(3^5)

x=ln(41)/ln(243)
