Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
Answer:
Unitary Method
Step-by-step explanation:
If the item is not listed with the unit price we can use different methods to calculate its unit price.
Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.
We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.
For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:
6 pounds costs $7.00
1 pound costs:
dollars.
And that is how we calculate the price of each unit.
Ur 1 solution is where the lines intersect, which is (1,4)
If a sample consists of 1900 scores from sample no. 476th will be above the first quartile.
<h3>What are mean, median, and mode?</h3>
The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
Given a sample consisting of 1900 scores.
∴ The no. of samples that would be above quartile is the next sample from (1/4)th of 1900 which is,
= (1/4)×1900 + 1.
= 475 + 1.
= 476.
So from sample no. 476th will be above the first quartile.

P(2oranges and 1lemon)=2/3 (orange) · 1/2 (lemon)
P(2O and 1L) = 2/6 = 1/3
1/3 chance of getting 2 orange and 1 lemon out of the bag.
