Solve for x 9^(x+2)=27^(8)
Answer:
I believe the answer is x=10
Hope this is correct! :)
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] {9}^{(x + 2)} = {27}^{8} \\ [/tex]
[tex]( { {3}^{2} })^{x + 2} = ({ {3}^{3} })^{8} [/tex]
[tex] {3}^{2 \times (x + 2)} = {3}^{3 \times 8} [/tex]
[tex] {3}^{2(x + 2)} = {3}^{24} [/tex]
Thus :
[tex]2(x + 2) = 24[/tex]
Divide sides by 2
[tex] \frac{2(x + 2)}{2} = \frac{24}{2} \\ [/tex]
[tex]x + 2 = 12[/tex]
Subtract sides 2
[tex]x + 2 - 2 = 12 - 2[/tex]
[tex]x = 10[/tex]

Of the 345 7th graders in music programs, 35% are in choir, 25% are in orchestra and the remaining are in band. How many 7th graders in music programs are in band?
Answer: 138
Step-by-step explanation:
Number of 7th graders in music programs = 345
Percentage in choir = 35%
Percentage in orchestra = 25%
Percentage in band = 100% - (35% + 25%) = 100% - 60% = 40%
The number of 7th graders in music programs are in band will then be:
= Percentage in band × Total 7th graders
= 40% × 345
= 0.4 × 345
= 138 students

What is the length of the unknown side of the right triangle?
A right triangle with hypotenuse x and legs 21 and 20
21
29
400
441
According to Pythagoras theorem,
h² = b² + h²
=> x² = 21² + 20²
=> x² = 441 + 400
=> x = √841
=> x = 29
Thus, the length of the unknown side is 29 units.

3x-1/5=x+1/3 solve for x
Answer:
x = 2
Step-by-step explanation:
First, you cross multiply then that will give you
9x - 3 = 5x + 5
collect like terms
9x - 5x = +5 + 3
= 4x = 8
Divide both sides by the coefficient of x that's 4
= 2

2(6-2x)-2x=2(5+x)-4 value of x?
Answer:
x= 3/4
Step-by-step explanation:
I looked it up. Hope this helps
Answer:
x = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Given
2(6 - 2x) - 2x = 2(5 + x) - 4 ← distribute parenthesis on both sides
12 - 4x - 2x = 10 + 2x - 4 ← simplify both sides
12 - 6x = 6 + 2x ( subtract 2x from both sides )
12 - 8x = 6 ( subtract 12 from both sides )
- 8x = - 6 ( divide both sides by - 8 )
x = [tex]\frac{-6}{-8}[/tex] = [tex]\frac{3}{4}[/tex]
A recipe calls for 3 1/2 cups of milk and makes 10 servings. How many cups of milk are needed for 8 servings? (Hint: Set up a proportion, don’t forget to label!)
Answer:
2.8 or 2 4/5
Step-by-step explanation:
Here's our proportion of cups of milk to servings
3 1/2:10 For my sake I'm using decimals
3.5:10
Now let's try to get our servings to 1 (a unit rate)
0.35:1 I divided by 10 on each side
We need 8 servings not 1 so let's multiply 8 on each side
2.8:8
In case you want it in fraction form we can do 2 8/10 and simplify it to 4/5 by dividing by 2. Our answer is 2.8 or 2 4/5 cups of milk for 8 servings.
Solve for X. -15 = 22x + 7
Answer: x=-1
Step-by-step explanation: Here is one way of answering this question. First you need to subtract 7 from both sides and that will leave you with -22=22x. Then you just divide 22 on both sides. So that will give you an answer of -1=x or x=-1

Answer:
x = 59
Step-by-step explanation:
All the angles in a triangle add up to 180
Add all the known angles
83 + 38 = 121
To find the third angle, subtract the total of all the angles by the total of the known angles
180 - 121 = 59

A diver descended 46.36 feet in 12.2 minutes.What was the divers average change in elevation per minute? The average change in elevation per minute was ?Ft per minute
Answer:
The average change in elevation per minute is 3.8 ft per minute
Step-by-step explanation:
Here. we want to calculate the average change in elevation per minute
To calculate this, we simply need to divide the total descent over the total number of minutes
Mathematically, that would be;
46.36 feet / 12.2 minutes = 3.8 feet per minute

Which of these is equivalent to 1 over x to the power of 5 ? 1 fifth x negative x to the power of 5 x to the power of 5 x to the power of negative 5 end exponent
Answer:
x^-5 = x to the power of negative 5
Step-by-step explanation:
Which of these is equivalent to 1 over x to the power of 5 ?
Mathematically this is expressed as
(1/x)⁵
We have a rule when it comes to expressing power
(1/a)^b = a^-b
Hence, applying this rule to our question
(1/x)⁵ = (1/x)^5
= x^-5
This is written in words as:
x to the power of negative 5
