What is the solution of the system ?
2x+3y=4
x-y=-3
The solution to the system of equations 2x + 3y = 4 and x - y = -3 is (x, y) = (-1, 2).
To solve this system, we can use the method of substitution or elimination. For example, here's how we can use the elimination method:
Multiply the second equation by 3 to get 3x - 3y = -9.Add this new equation to the first equation to eliminate y: (2x + 3y) + (3x - 3y) = 4 - 9.Simplify to get 5x = -5.Divide both sides by 5 to find x = -1.Substitute x = -1 into the second equation to solve for y.So we get -1 - y = -3 which simplifies to y = 2.The solution to the system of equations is (x, y) = (-1, 2).

A cape is on sale for 30% off. It's sale price was $126. What is the original price?
The original price of the cape, before a 30% discount that resulted in a sale price of $126, was $180. Since 70% of the original price equals the sale price, dividing $126 by 0.7 yields the original price.
Explanation:To find the original price of an item that has been discounted by 30%, we first recognize that the sale price represents 70% of the original price because 100% - 30% = 70%. If $126 is the sale price, it is 70% of the original price.
To find 100% of the original price, you can set up a proportion or simply divide the sale price by 0.7.
Using division:
Original Price = Sale Price / 0.7
Original Price = $126 / 0.7
Original Price = $180
Therefore, the original price of the cape was $180.
When we include sales tax in the calculation, assuming we know the tax rate, we would add that to the original price to get the total cost that will be paid at the register.
However, this question doesn't provide a tax rate, so we only calculate the original price.
The equation that represents the canned goods order is 24x + 64y = 384, where x = number of minutes producing fruit cans and y = number of minutes producing vegetable cans. What is the real world meaning of the x-intercept?
The x-intercept will be at (16,0) and the y-intercept at (0, 6).
We have to solve for y by substituting 0 as the value of x. This will be:
24x + 64y = 384
24(0) + 64y = 384
64y = 384
y = 384/64
y = 6
We have to solve for x by substituting 0 as the value of y. This will be:
24x + 64y = 384
24x + 64(0) = 384
24x = 384
x = 384/24
x = 16
In conclusion, the x-intercept will be at (16,0) and the y-intercept at (0, 6).

Answer:
Sample Answer: The x-intercept, at the point (16, 0) indicates the choice to produce fruit for 16 minutes. In 16 minutes, producing 24 cans of fruit a minute, all 384 cans for the order will be completed. The zero for the y-value represents that no time is spent producing cans of vegetables.

A race car travels at a speed of 230 miles per hour. The race track on which the car is competing is 400 miles long. About how long does it take for the car to finish, disregarding pit stops and yellow flags?
A) 174 minutes
B) 345 minutes
C) 1 hour 45 minutes
D) 2 hours 14 minutes
Answer:
Option(c)
Step-by-step explanation:
The race track on which the car is competing miles= 400 miles
A car travels with speed= 230 miles per hour
We have to find time taken for the car to finish
As we know,
Time taken to cover certain distance=[tex]\frac{Distance}{Time}[/tex]
Time taken to cover certain distance=[tex]\frac{400}{230}[/tex]
Time taken to cover certain distance=[tex]\frac{40}{23}[/tex]
Time taken to cover certain distance=1 hour 45 minutes
Hence, the correct answer is option(c)

Marta uses 1 piece of paper and 1 piece of ribbon to make kites. The paper comes in packs of 3 pieces and the ribbon comes in packs of 4 pieces. What is the least number of kites Marta can make without any supplies left over?
Answer:
The least number of kites Marta can make without any supplies left over is 12.She uses four packs for paper and only three packs for ribbons.Step-by-step explanation:
Givens:
Martha needs 1 piece of paper and 1 piece of ribbon.Paper is in packs of 3 pieces, and ribbon is in packs of 4 pieces.If Martha needs 1 piece of paper and ribbon, then she need to use 4 packs of paper and 3 packs of ribbons, because when she uses one pack of paper, she use it all, but from the pack of ribbons, it remains some.
First pack.From the first pack Marta has 3 papers and 4 ribbons. So, she uses all 3 papers, and 3 ribbons, and there remains 1 ribbons without use.
Second pack.From the second pack, Marta uses 3 papers but only 2 ribbons, because she also uses the one ribbon that left from the first pack. So, from the second pack, she only uses 2 ribbons, and there are 2 ribbons left.
Third pack.From the third pack, she again uses all three papers, but only 1 ribbon, so there is three ribbons left.
Fourth pack.From the fourth pack she uses three papers agains, but she doesn't need a new pack of ribbons, because she has three from the third pack.
Now, specifically, the least common number refers to the least common multiple of 3 and 4, which is 12, because if we write down the multiples for both numbers, we have:
3, 6, 9, 12, 15, ...
4, 8, 12, 16, 20,...
As you can see, the least common number is 12.
Therefore, the least number of kites Marta can make without any supplies left over is 12.
A recipe calls for 1/4 cup of flour. Carter does not have a quarter-cup measuring cup, though he has a measuring cup that holds an eighth of the cup. How can carter measure the flour he needs for his recipe.
Answer:
Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.
Step-by-step explanation:
To solve this problem you should use a simple equation. As Carter has a cup that holds an eighth of the cup and he need to add a quarter cup to the recipe he needs to find a factor that multiplied by [tex]\frac{1}{8}[/tex] gives as result the [tex]\frac{1}{4}[/tex] he needs, that is:
1. Let´s name x the factor and we have the following equation:
[tex]\frac{1}{8}*x=\frac{1}{4}[/tex]
2. Solving for x:
[tex]\frac{x}{8}=\frac{1}{4}[/tex]
[tex]x=\frac{8}{4}[/tex]
[tex]x=2[/tex]
The result x=2 means that Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.

HALP me with this question Nicole is making 1,000 bows for people who donate to the library book sale.She needs a piece of ribbon that is 0.75 meter long for each bow.How many meters of ribbon does Nicole need to make the bows?
Explain how to find the answer and what's the anwer?
Nicole needs 750 meters of ribbon to make 1,000 bows, with each bow requiring 0.75 meters of ribbon. This is calculated by multiplying 1,000 by 0.75.
To determine how many meters of ribbon Nicole needs to make 1,000 bows where each bow requires 0.75 meters of ribbon, we need to perform a simple multiplication. Given:
1. Number of bows = 1,000
2. Length of ribbon per bow = 0.75 meters
We multiply these two values:
1,000 bows × 0.75 meters per bow = 750 meters
Thus, Nicole needs 750 meters of ribbon to make all the bows.
Let’s break down the process step-by-step:
Identify the number of bows Nicole wants to make (1,000).Identify the length of ribbon needed for each bow (0.75 meters).Perform the multiplication: 1,000 × 0.75.The result gives the total meters of ribbon required (750 meters).What are four equivalent expressions for 42+18
