To undo what has been done to the variable, on both sides of the equation. The solution of the equation is . Check the solution by substituting in for g and simplifying.
Answer:
The variable, g, represents
✔ the number of grapes Graciella had
.
The equation that correctly models the problem is
✔ g/6 = 16
.
To undo what has been done to the variable,
✔ multiply by 6
on both sides of the equation.
The solution of the equation is
✔ g = 96
.
Check the solution by substituting
✔ 96
in for g and simplifying.
The solution of the equation will be g = 96.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
The variable, g, represents the total number of grapes that Graciella had.
The equation that correctly models the problem is:
g/6 = 16
To undo what has been done to the variable, we can multiply both sides of the equation by 6:
g = 6 x 16
g = 96
Therefore, Graciella had 96 grapes.
To check the solution, we substitute 96 for g in the original equation:
g/6 = 16
96/6 = 16
16 = 16
The equation is true, so our solution of g = 96 is correct.

Determine the domain of (f/g)(x) when f(x)=1/x and g(x)= sqrt x+8
(answer choices in photo)
Answer:
(−8,0)∪(0,∞)
Step-by-step explanation:
This is composition, which I'm going to assume you've covered (sorry if I use any weird terms because of that).
So, anyway, (f/g)(x) is basically [tex]\frac{f(x)}{g(x)}[/tex].
In this case, the answer would be [tex]\frac{\frac{1}{x} }{\sqrt{x+8} }[/tex]
I'm going to assume we're using the real number system.
In that case, x can't be less than 0 (can't even be equal to because divide by zero error
So, [tex]\sqrt{x+8} > 0[/tex]
Solve for x by squaring.
[tex]\sqrt{x+8} > 0[/tex]
[tex]x > -8[/tex]
However, in the numerator, there is 1/x. A number divided by 0 is undefined. So, x has to be greater than -8, and it can't be 0.
So, with that, the interval notation is like this.
(−8,0)∪(0,∞)

The sum of two numbers is 68. The second number is 2 more than twice
the first.
Answer:
22 and 46
Step-by-step explanation:
let
one number is x
another is 2x+2
now 2x+2+x=68
or, 3x+2=68
3x=66
or x=66/3=22
so one number is 22 and another is (22X2+2)=46

A rectangle has a perimeter of 30 ft. Find a function that models its area A in terms of the length x of one of its sides. What side length, x, yields the greatest area. What is that area?
Answer:
Step-by-step explanation:
Let the other side of the rectangle be y. The perimeter of the rectangle is expressed as P = 2(x+y)
Given P = 30ft, on substituting P = 30 into the expression;
30 = 2(x+y)
x+y = 15
y = 15-x
Also since the area of the rectangle is xy;
A = xy
Substitute y = 15-x into the area;
A = x(15-x)
A = 15x-x²
The function that models its area A in terms of the length x of one of its sides is A = 15x-x²
The side of length x yields the greatest area when dA/dx = 0
dA/dx = 15-2x
15-2x = 0
-2x = -15
x = -15/-2
x = 7.5 ft
Hence the side length, x that yields the greatest area is 7.5ft.
Since y = 15-x
y = 15-7.5
y = 7.5
Area of the rectangle = 7.5*7.5
Area of the rectangle = 56.25ft²
find the circumference of a circle that has a radius of 212 mm
Answer:
1332.04
Step-by-step explanation:
C=2πr=2·π·212≈1332.03529
Answer:
1332.035 millimeters
Step-by-step explanation:
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

is it 1 or 16...
nevermind about my answer then oops
Answer:
16
Step-by-step explanation:
Using PEMDAS, anything in the parenthesis must be solved first which would make 8/2(2+2) turn into 8/2(4). Next for this equation according to PEMDAS, you must divide, turning 8/2(4) into 4(4), and 4 times 4 is 16. :)

Digital Cameras
The cost and revenue equations for a company that sells digital cameras are given by
R(x) = x(125 -0.0005x)
And
C(x) = 3.5x + 185000
Where R and C are measured in dollars and x represents the number of cameras sold. How many
cameras must be sold to obtain a profit of at least $6,000,000?
Answer:
283,957 cameras
Step-by-step explanation:
Profit generated = cost - Revenue
Given
Cost function C(x) = 3.5x + 185000
Revenue function R(x) = x(125 -0.0005x)
Profit = $6,000,000
To get the value of x, we will substitute the given parameters into the formula as shown;
$6,000,000 = 3.5x + 185000 - x(125 -0.0005x)
$6,000,000 = 3.5x + 185000 - 125x +0.0005x²
0.0005x²-121.5x + 185000 - 6,000,000 = 0
0.0005x²-121.5x-5815000 = 0
On solving the resulting quadratic equation
x = 283,956.91736581 and -40956.917365805
Ignoring the negative value, the minimum camera that must be sold is approximately 283,957 cameras
