Number of bracelet Jessica can make in 30 minutes=2Number of bracelet Jessica can make in 60 minutes=4Number of bracelet Jessica can make in 90 minutes=6Number of bracelet Jessica can make in 120 minutes=8Number of bracelet Jessica can make in 180 minutes=12Jessica can make 12 bracelet in 180 minutes (3 hours).
Step-by-step explanation:
Unitary methodNumber of bracelet Jessica can make in 30 minutes=2
Number of bracelet Jessica can make in 180 minutes=(180×2)/30=12
or,
Arithmetic methodNumber of bracelet made by Jessica is directly proportional to the time taken by her.
Number of bracelet made by Jessica=k×time taken by her, where k is a constant
2k=304k=606k=908k=120In all cases value of k is 15
Therefore,
Let the number of bracelet be x and putting the value of k, we get
xk=180 minutes (3 hours)
15x=180
x=180/15
x=12

Put the steps in order to show how to solve the equation 4y - 7 = 25
Answers
Answer: E, A, D, C, B
Step-by-step explanation:
First, we need to get y alone. So we will add 7 to the side of the equation that has the 4y in it.
So the first one will be.
Add 7 to both sides of the equation.
Now the second one is
4y = 25 + 7 Because what you do to one side of the equation, you do to the other. So we add 7 to 25.
Then the 3rd one will be 4y = 32 because 25+7 is equal to 32. But we still have that 4y on the other side of the equation. So the next equation is 4y = 32.
The second to last step is Divide both sides by 4 because thats
how you isolate y. So once you divide both sides by 4. You will get 8. Leading you into the next and final step.
Y = 8
And thats how you do it!

Let x and y be the two numbers. Let's say that either x = y or x < y. To keep things relatively simple, we'll make both of these numbers positive.
We are told that they add to 50, so
x+y = 50
which solves to
y = 50-x
Their product is
x*y = x*(y) = x*(50-x) = 50x - x^2 = -x^2 + 50x
So the function
f(x) = -x^2 + 50x
will give us the product f(x) for the input x. Keep in mind that if we know what x is, then y = 50-x is used to find y.
The function f(x) graphs out a parabola that opens downward. Check out the diagram below. This means the very peak point of the parabola is what we're after. This is the vertex. At the vertex, we'll have f(x) maxed out as much as possible. This occurs at the point (25,625) meaning x = 25 and y = 50-x = 50-25 = 25 both multiply to x*y = 25*25 = 625, which is the largest possible product.
In short, this provides a visual means to confirm you have the correct answers for part b.

Answer:
(x, y) = (-1, 5/2)
Step-by-step explanation:
The only variable with a coefficient that has a magnitude of 1 is x in the first equation. Using that equation, we can write an expression for x:
x = 2y -6
This can be substituted for x in the second equation.
(7/2)(2y -6) +7y = 14
7y -21 +7y = 14 . . . . . . eliminate parentheses
14y = 35 . . . . . . . . . . . add 21
y = 35/14 = 5/2 . . . . . divide by the coefficient of y
x = 2(5/2) -6 = -1
The solution is (x, y) = (-1, 5/2).

Find the equation of the line that is parallel to this line and passes through the point (5,6).
Answers
Answer:
See explanations below
Step-by-step explanation:
Consider the line y=-2x+3.
The equation in point slope form is expressed as y-y0=m(x-x0)
m is the slope
(x0,y0) is the point
If the Line is parallel, slope m = -2
Substitute
y-6 = -2(x-5)
y-6 = -2x+10
y+2x = 10+6
y+2x = 16
Is the line is perpendicular
Slope m = -1/-2
m = 1/2
Substitute into the formula
y - 6 = -1/2(x-5)
2(y-6) = -(x-5)
2y-12 = -x+5
2y+x = 5+12
2y+x = 17
1.5y - 15 + 1.8y = -10
