Answer:
a simultaneous equation is a set of equations. you need at least another equation.
Answer:
Step-by-step explanation:
Let's solve for x.
3x−4y= 1/ 3
Step 1: Add 4y to both sides.
3x−4y+4y= 1/ 3 +4y
3x=4y+ 1/ 3
Step 2: Divide both sides by 3.
3x/ 3 = 4y+ 1/ 3
3 x= 4/ 3 y+ 1/ 9
Answer:
x= 4/ 3 y+ 1/ 9
Let's solve for y.
3x−4y= 1/ 3
Step 1: Add -3x to both sides.
3x−4y+−3x= 1/ 3 +−3x
−4y=−3x+ 1/ 3
Step 2: Divide both sides by -4.
−4y/ −4 = −3x+ 1/ 3
−4 y= 3/ 4 x+ −1/ 12
Answer:
y= 3/ 4 x+ −1/ 12
tim bought all of the 2 3 over 4 lb packages for a party
How many pounds of meat fid tim buy?
Answer: he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)
Step-by-step explanation:
We know that Tim bought all of the two 3/4 lb packages for a party.
Then he bought 2 packages. Such that each package has 3/4 lb meat.
Then the total amount of meat that Tim has is equal to 2 times the amount of meat in each package, this is:
Total meat = 2*(3/4 lb) = (6/4 lb)
and we can write 6 = 4 + 2
then:
Total meat = 6/4 lb = (4 + 2)/4 lb = (4/4 + 2/4) lb = (1 + 1/2) lb
So he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm. How much ribbon will she need?
Answer:
[tex]220[/tex] cm
Step-by-step explanation:
We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be [tex]2(l+w)[/tex], where [tex]l[/tex] is the rectangle's length and [tex]w[/tex] is the rectangle's width. We are given that [tex]l=70[/tex] and [tex]w=40[/tex]. Therefore, [tex]2(70+40)=2*110=220[/tex] cm of ribbon will be needed. Hope this helps!
6) solve the equation for m
Answer:
m=48
Step-by-step explanation:
m/3=18-2
m/3=16
m=16x3
m=48
Answer:
m=48
Step-by-step explanation:
Subtract 2 from both sides
2+m/3-2=18-2
Simplify
m/3=16
Multiply both sides by 3
3m/3=16*3
simplify
m=48

Use the information to find an equation (y=mx+b) for the amount of Sponsorship money (Y) you an make for each day of the trip. Show your work and explain your steps below. Coca Cola 5 days - $134 10 days - $164 15 days - $194 20 days - $224
Answer:
y = 6x + 104
Step-by-step explanation:
Given the equation in the form:
y = mx + b
m = slope ; b = intercept
Given the data:
5 days - $134 10 days - $164 15 days - $194 20 days - $224
To obtain the slope, Pick the points :
(5, 134) and (20, 224)
Slope = y2 - y1 / x2 - x1
Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6
Plugging into the equation :
We have ;
y = 6x + b
Picking any point from the data and plugging in to solve for b:
(10, 164)
164 = 6(10) + b
164 = 60 + b
b = 164 - 60
b = 104
Equation finally becomes ;
y = 6x + 104

Find the 75th term of the arithmetic sequence -17, -13, -9....
Answer:
The 75th term of the arithmetic sequence -17, -13, -9.... is:
[tex]a_{75}=279[/tex]
Step-by-step explanation:
Given the sequence
[tex]-17, -13, -9....[/tex]
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]-13-\left(-17\right)=4,\:\quad \:-9-\left(-13\right)=4[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=4[/tex]
The first element of the sequence is:
[tex]a_1=-17[/tex]
now substitute [tex]d=4[/tex] and [tex]a_1=-17[/tex] in the nth term of the sequence
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=4\left(n-1\right)-17[/tex]
[tex]a_n=4n-21[/tex]
Now, substitute n = 75 in the [tex]a_n=4n-21[/tex] sequence to determine the 75th sequence
[tex]a_n=4n-21[/tex]
[tex]a_{75}=4\left(75\right)-21[/tex]
[tex]a_{75}=300-21[/tex]
[tex]a_{75}=279[/tex]
Therefore, the 75th term of the arithmetic sequence -17, -13, -9.... is:
[tex]a_{75}=279[/tex]

What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Number of red marbles in the bag=1/2
Number of blue marbles in the bag=1/4
Number of green marbles in the bag=1/6
Number of yellow marbles in the bag=1/12
Now,
To determine the most likely color of the marble that will be chosen, we need to calculate the probability of selecting each color. The probability of selecting a red marble is 1/2, the probability of selecting a blue marble is 1/4, the probability of selecting a green marble is 1/6, and the probability of selecting a yellow marble is 1/12.
To compare the probabilities, we need to find a common denominator. The common denominator for 2, 4, 6, and 12 is 12. So, we can rewrite the probabilities as:
Probability of selecting a red marble = 6/12
Probability of selecting a blue marble = 3/12
Probability of selecting a green marble = 2/12
Probability of selecting a yellow marble = 1/12
Since the probability of selecting a red marble is the highest among all the colors, it is the most likely color to be chosen.
Therefore, by probability the answer will be red marble.
