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

The formula for the volume V of a cylinder is V=pier2h, where r is the radius of the base and h is the height of the cylinder. Solve the formula for h.
Answer:
h = V / πr²
Step-by-step explanation:
V = πr²h
Where,
V = volume of a cylinder
π = π
r = radius of the cylinder
h = height of the cylinder
V = πr²h
Solve for h
V = π × r² × h
Divide both sides by π × r²
h = V / π × r²
h = V / πr²
Height of the cylinder = volume of the cylinder / pie × r²

Brad buys two packages of mushrooms. He paid $11.25 for 2/3 lb of Cremini mushrooms and $7.99 for 1/2 lb of Chanterelle mushrooms. Which mushroom cost less per pound?
Cremini mushrooms cost less by $0.10
Chanterelle mushrooms cost less by $0.10
Chanterelle mushrooms cost less by $0.90
Cremini mushrooms cost less by $0.90
Answer:
C. (Chanterelle mushrooms cost less by $0.90)
Step-by-step explanation:
Divide 11.25 by 2/3, for the total amount of pound for the Cremini.
Do the same thing for Chanterelle, but the numbers given for it.
We than find out that Cremini=16.87, and Chanterelle=15.98
Now that we know Cremini is more that Chanterelle, we need to find the difference, by subtracting The bigger number by the smaller number.
Our answer is 0.89, but we will round it to 0.90.
Now we know that the Cremini costs more by $0.90, and the Chanterelle costs less by $0.90
Answer:
Step-by-step explanation:
Cost of 1 lb of Cremini mushrooms= 11.25×3/2=33.75/2=16.875 $≈$16.88
Cost of 1 lb of Chanterelle mushrooms=7.99×2/1=$15.98
Chanterelle mushrooms cost 16.88-15.98=$0.90 less
F a seed is planted, it has a 75% chance of growing into a healthy plant. If 9 seeds are planted, what is the probability that exactly 2 don't grow?
Answer:
0.3
Step-by-step explanation:
Given that:
Probability of growing into a healthy plant = probability of success (p) = 75% = 0.75
Number of seeds planted(n) = 9
Probability that exactly 2 don't grow is equivalent to having 7 that grows (9 - 2) = 7 = r
Using binomial distribution formula :
nCr * p^r * (1 - p)^(n-r)
9C7 * 0.75^7 * (1 - 0.75)^(9 - 7)
9C7 * 0.75^7 * 0.25^2
36 * 0.13348 * 0.0625
= 0.3003387
= 0.3
Hence, probability that exactly 2 don't grow is 0.3

WHICH GRAPH SHOWS A FUNCTION AND ITS INVERSE.
brainliest plz hurry timed test!!
A slope is also known as the gradient of a line. The correct option is B.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
Since for the two functions to be inverse of each other, the line of equations must bisect each other at 90° so that the product of the slope of the two equations is equal to -1.
For the second graph, the slope of the blue line is,
m₁ = (-1-0)/(0-4) = 0.25
The slope of the green line is,
m₂ = (-4-0)/[0-(-1)] = -4
Now, the product of the slope can be written as,
0.25×-4 = -1
Since the product is -1, the function is inverse of each other.
Hence, the correct option is B.

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
please help with math problem !! (explanation needed) -3 + (8 – 2x)4 = 29
Answer:
x = -4
Step-by-step explanation:
To solve this type of question, put the term with the exponent on one side and the numerical term on the other side
∵ -3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29
→ Add 3 to both sides
∵ -3 + 3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29 + 3
∴ [tex](8-2x)^{\frac{5}{4}}[/tex] = 32
→ Remember is [tex]x^{\frac{m}{n}}[/tex] = a, then x = [tex]a^{\frac{n}{m}}[/tex], that means to move the exponent
from one side to the other side reciprocal it
∴ 8 - 2x = [tex](32)^{\frac{4}{5}}[/tex]
→ Use your calculator to find the value of [tex](32)^{\frac{4}{5}}[/tex]
∵ [tex](32)^{\frac{4}{5}}[/tex] = 16
∴ 8 - 2x = 16
→ Subtract 8 from both sides
∴ 8 - 8 - 2x = 16 - 8
∴ -2x = 8
→ Divide both sides by -2
∴ x = -4
To check the solution substitute x by -4 in the left side and find its answer if it equals the right side, then the solution is right
∵ Left side ⇒ -3 + (8 - 2 × -4)[tex]^{\frac{5}{4}}[/tex] = -3 + (8 + 8)[tex]^{\frac{5}{4}}[/tex] =-3 + (16)[tex]^{\frac{5}{4}}[/tex] = -3 + 32 = 29
∵ Right side = 29
∴ The solution is right
