6+ 3x = 15 with work!
Answer:
X=3
Step-by-step explanation:
Rearrange terms
6+3=15
3+6=15
Subtract from both sides of the equation
3+6=15
3+6−6=15−6
Simplify
Subtract the numbers
Subtract the numbers
3=9
x=3
X = 3.
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex]3x = 15 - 6[/tex]
2) Simplify 15 - 6 to 9.
[tex]3x = 9[/tex]
3) Divide both sides by 3.
[tex]x = \frac{9}{3} [/tex]
4) Simplify 9/3 to 3.
[tex]x = 3[/tex]
So, therefor, 5he answer is x=3.

If the flea is to the left of zero and the absolute value of its location is 3.6, where on the number line is it?
Answer:
I JUST HAD THIS QUESTION AND I GOT 3/3, THE ANSWERS -3.6 BECAUSE THE ANSWER HAS TO BE TO THE LEFT OF THE ZERO, AND THE NUMBER IS 3.6, SO IF ITS TO THE LEFT AND THATS THE NUMBER THEN ITS -3.6 PERIODDDDD
Step-by-step explanation:
Answer:
If the flea is to the left of zero and its absolute value is 3.6, it means that the flea is located at a negative value on the number line. Since the absolute value of its location is 3.6, we can deduce that the flea is located at -3.6 on the number line.

Find the volume of the cone
Answer:
formulae : 1/3 × area of base × height
= 1/3 × 6 × 8
= 1×2×8
=16
if 8^y = 16^x + 2 what is the value of Y
Answer:
y= -8
Step-by-step explanation:
8^y = 16^(y+2)
//to solve make the base equal, both 8 and 16 are powers of (2
(2^3)^y = (2^4)^(y+2)
//simplify, remember when doing this multiply the powers
2^3y = 2^(4y+8)
// now we can just make the 2 powers equal
3y = 4y+8
0=y+8
y= -8
check:
8^(-8) = 16^(-6)
2^(-24) = 2^(-24)

Factorize using suitable identity
a²-(b-c)²
Step-by-step explanation:
We have,
a ^2 −(b−c) ^2
Since, x ^2 −y ^2 =(x+y)(x−y)
Thus,
⇒[a−(b−c)][a+(b−c)]
⇒(a−b+c)(a+b−c)
Hence, this is the answer.

A sample of 600 g of radioactive lead-210 decays to polonium-210 according to the function A(t) = 600e ^-0.032t, where t is time in years. Find the amount of radioactive lead remaining after
(a) 3 yr
(b) 8 yr
(c) 15 yr
(d) find the half-tie
round to the nearest integer as needed.
The amount of radioactive lead remaining after 3 years is 545gm.
The amount of radioactive lead remaining after 8 years is 464gm.
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radio active lead is 21.66 years.
Given that,
A sample of 600 g of radioactive lead-210 decays to polonium-210,
According to the function A(t) = 600e ^-0.032t,
Where, t is time in years.
We have to find,
Find the amount of radioactive lead remaining after.
According to the question,
Function [tex]A(t) = 600e^{(-0.032t)}[/tex]
After 3 years the amount of radioactive lead,[tex]A(3) = 600\times e^{(-0.032t)} \\\\A (3) = 600 \times \dfrac{1}{e^{0.032\times 3} } \\\\e^{0.096} = 1.10075\\\\A (3) = 600 \times \dfrac{1}{e^{0.096} } \\\\A (3) = 600 \times \dfrac{1}{1.10075} } \\\\A(3) = \dfrac{600}{1.10075}\\\\A(3) = 545gm[/tex]
The amount of radioactive lead remaining after 3 years is 545gm.
After 8 years the amount of radioactive lead,[tex]A(8) = 600\times e^{(-0.032t)} \\\\A (8) = 600 \times \dfrac{1}{e^{0.032\times 8} } \\\\e^{0.0256} = 1.129175\\\\A (8) = 600 \times \dfrac{1}{e^{0.0256} } \\\\A (8) = 600 \times \dfrac{1}{1.129175} } \\\\A(8) = \dfrac{600}{1.129175}\\\\A(8) = 464gm[/tex]
The amount of radioactive lead remaining after 8 years is 464gm.
After 15 years the amount of radioactive lead,
[tex]A(15) = 600\times e^{(-0.032t)} \\\\A (15) = 600 \times \dfrac{1}{e^{0.032\times 15} } \\\\e^{0.48} = 1.61607\\\\A (8) = 600 \times \dfrac{1}{e^{0.48} } \\\\A (8) = 600 \times \dfrac{1}{1.61607} } \\\\A(8) = \dfrac{600}{1.61607}\\\\A(8) = 371gm[/tex]
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radioactive lead,[tex]A(15) = 600\times \dfrac{1}{2} = 600e^{-0.032t} \\\\= e^{(-0.032t)} = \dfrac{1}{2}\\\\Taking \ log \ on \ both \ sides\\\\= -0.032t = ln2\\\\= t = \dfrac{ln2}{-0.032}\\\\= t = 21.660\\\\= t = 21.66 years[/tex]
The half-tie for radio active lead is 21.66 years.

A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?
Answer:
0.5
Step-by-step explanation:
Sample mean, x = 6 points greater than population mean ;
Population mean, m = 16
Standard deviation, s = 12
Zscore = (sample mean - population mean) / standard deviation
Zscore = (x - m) / s
x = 16 + 6 = 22
Zscore = (22 - 16) / 12
Zscore = 6 /12
Zscore = 0.5

The first round of a racquetball tournament begins with 148 players. Every round, half of the players lose and are eliminated from the tournament leaving 74 players in the second round. The tournament continues in the same fashion until one player finally wins the tournament. Determine if the scenario describes an arithmetic or a geometric sequence then write the formula for the sequence described.
Answer:
Notice that 99 players need to be eliminated for there to be declared a winner. Notice also that every match eliminates exactly one person. Therefore, 99 matches are needed to eliminate 99 people and therefore declare a winner. The rest of the information is irrelevant. Therefore, the total number of matches is text divisible by 11.

A hike starts at an elevation of 13 and four-fifths feet below sea level and ends at an elevation that is 1,542 feet higher. How high is the hiker, in feet, above sea level at the end of the hike?
Answer:
the height above the seal level at the end of the hike is [tex]1528 \frac{1}{5} feet[/tex]
Step-by-step explanation:
The computation is shown below:
[tex]= 1542 - 13 \frac{4}{5}\\\\= 1542 - \frac{69}{5}\\\\= \frac{7710-69}{5} \\\\= \frac{7641}{5}\\\\= 1528 \frac{1}{5} feet[/tex]
