For this case we must find the value of the variable of the following equation:

\frac {2} {3} x + 4 = \frac {1} {2} x + 5

Subtracting \frac {1} {2} x from both sides:

\frac {2} {3} x- \frac {1} {2} x + 4 = 5\\\frac {4-3} {6} x + 4 = 5\\\frac {1} {6} x + 4 = 5

Subtracting 4 from both sides:

\frac {1} {6} {x} = 5-4\\\frac {1} {6} x = 1

Multiplying by 6 on both sides:

x = 6 * 1\\x = 6

Answer:

x = 6

Answer:

x= about 5

Step-by-step explanation:

2/3x+4=1/2x+5

-4 on both sides

2/3x=1/2x+1

-1/2 on both sides

0.1666666666666..., so 0.2

0.2x=1

divide 0.2 on both sides

x=5

A church rings its bells every 15 minutes, the school rings its bells every 20 minutes and the day care center rings its bells e
Dima020 [189]

Answer:

5 : 00 PM

Step-by-step explanation:

Given,

Church ring bells every 15 minutes,

School rings its bells every 20 minutes,

And, day care center rings its bells every 25 minutes,

Thus, the number of minutes after which they will ring together = LCM (15, 20, 25)

∵ 15 = 3 × 5,

20 = 2 × 2 × 5,

25 = 5 × 5,

Thus, LCM (15, 20, 25) = 300

Now, 1 minute = 1/60 hours ⇒ 300 minutes = 5 hours,

Hence, after 5 hours they will ring together,

If they rang at 12:00 PM,

Then they will ring after 5 hours that is 5:00 PM.

The degree of 5x4y2z3 is 9.<br> O True<br> O False
pashok25 [27]

Answer:

true

Step-by-step explanation:

because the expression shown is a monomial we simply add the degrees of each term

4 + 2 + 3 = 9

5x4y2z3 indeed has a degree of 9

Note: if the terms were being added we take the highest degree and that is the degree of the expression.

ex. 5x^4 + y^2 + z^3 would have a degree of 4

A population of 1,750 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 11 years? Roun
Triss [41]

Answer:

The answer is C. 546.

If a population decreases by 11%, that means that 89% (100% - 11% = 89%) of cheetahs remains each number. 89% can be expressed as 0.89, so to calculate the change of the population, we must each year multiply the number of cheetahs by 0.89.

After 1 year:     1750 * 0.89 ≈ 1558

After 2 years:  1558 * 0.89 ≈ 1387

After 3 years:  1387 * 0.89 ≈ 1234

After 4 years:  1234 * 0.89 ≈ 1098

After 5 years:  1098 * 0.89 ≈ 977

After 6 years:  977 * 0.89 ≈ 870

After 7 years:  870 * 0.89 ≈ 774

After 8 years:  774 * 0.89 ≈ 689

After 9 years:  689 * 0.89 ≈ 613

After 10 years:  613 * 0.89 ≈ 546
