Missing part of the question:
Let x represent the length of the first piece. Write an equation that represents the ratio of the first piece of ribbon to the second piece. Be sure to define your variable or variable expressions.
Answer:
[tex]3x = 2y[/tex]
Step-by-step explanation:
Given
x = first
y = second
Required
Represent as an equation
From the question, when x is divided by y, it gives ratio of 2 to 3.
This implies that:
[tex]\frac{x}{y} = \frac{2}{3}[/tex]
Cross Multiply
[tex]3x = 2y[/tex]
Marty, Doc, and Einstein are all traveling very fast in
their cars. Marty and Doc's position over time are
shown below in the tables. Einstein only collected two
data points during his trip; after 3 hours he travelled
240 miles and after 4 hours he travelled 320 miles.
Who drove the fastest? Show work. Explain on the
lines below.
Answer:
Doc drove the fastest.
Step-by-step explanation:
The first thing you want to do is figure out how many milese they are traveling per hour. We know that Einstein has these two time stamps (hour/miles) ; 3/240 and 4/320.
so divide the hour by the number of miles:
3÷240=80
just to make sure I did the four hour one as well;
4÷320=80
Do the same thing for doc and marty!
Doc4÷340=85
Marty4÷100=0.04
The answer that you get from the division problems is the number of miles that they travel each hour.
Hope this helps!

Q4) The admission fee at a small fair is $2 for children and $4.00 for adults.
On a certain day, 350 people enter the fair and $1100 is collected.
How many children and how many adults attended?
Hint: Build up a system of two equations. Then solve it algebraically.
Consider that y is the number of kids and x is the number of adults.
9514 1404 393
Answer:
150 children200 adultsStep-by-step explanation:
The equations can be written as ...
y = 350 -x . . . . . . . . total number of people
4x +2y = 1100 . . . . . admission fees collected
Substituting for y, we have ...
4x +2(350 -x) = 1100
2x = 400 . . . . . . . . . . . . subtract 700, collect terms
x = 200
y = 350 -200 = 150
150 children and 200 adults attended the fair.

Can someone explain how the quadratic equation works with an example!
Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Step-by-step explanation: 6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0.

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?
Answer: 0.9kg
Step-by-step explanation:
Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.
Therefore,
Parcel A + Parcel B + Parcel C = 2.5
0.7 + x + x = 2.5
0.7 + 2x = 2.5
2x = 2.5 - 0.7
2x = 1.8
x = 1.8/2
x = 0.9
The mass of parcel C is 0.9kg

Vusi makes bead bracelets in three different designs.The first design uses 23 beads the second design uses 29 beads and the third design uses 31 beads.He has 750 beads and he wants to make the same number of bracelets using each design.How many beads will be left over?
Answer:
he will have 3 beads left over
Step-by-step explanation:
29 + 23 + 31 = 83 beads used for a set of 3 bracelets of the 3 designs
750/83 = the no. of sets of 3 bracelets of the 3 designs
750/83 = 9 sets with a remainder of 3
So, he will have 3 beads left over

Find the amount Erica owes at the end of 3 years if $6400 is loaned to her at a rate of 7% compounded monthly.
Answer:
$7840
Step-by-step explanation:
Given data
P=6400
r=7%
t= 3 years
The compound interest expression is given as
A= P(1+r)^t
Substitute
A= 6400(1+0.07)^3
A= 6400(1.07)^3
A= 6400*1.225
A= $7840
Hence at the end of 3 years she owes $7840
