Explain how you would create opposite terms for the x-variable in this system.
3x – 6y = –8
-1x+4y=6
Answers
Answer:
Your answer would be, You can use the Elimination Method, by Multiplying, One or Both Equations by a Constant.
Solve System of Linear Equation:
3x - 6y = -8, -1/4x + 4y = 6 ====> y = 32 /21; x = 8 / 21
Steps:
[ 3x - 6y = -8, -1 / 4x + 4y = 6 ]
Isolate x for 3x - 6y = -8: x = -8 + 6y / 3
3x - 6y = -8
Add 6y both sides:
3x - 6y + 6y = -8 + 6y
Simplify:
3x = - 8 + 6y
Divide Both sides by 3:
3x / x = -8 / 3 + 6y / 3
Simplify:
x = -8 + 6y / 3
Substitute:
x = -8 + 6y / 3
[ 1 / 4 * -8 + 6y / 3 + 4y = 6 ]
Isolate:
-1 / 4 -8 + 6y / 3 + 4y = 6
y = 32 / 21
For x = -8 + 6y / 3
Substitute:
y = 32 / 21
x = -8 + 6 / 3 * 32 / 21
-8 + 6 / 3 * 32 / 21
x = 8 / 21
The Solution to the Systems of Equations are: y = 32 / 21; x = 8 / 21

You want to buy some beans. A 9-ounce package costs $2.79. A 16-ounce
package costs $5.12. A 24-ounce package costs $7.20. Which package is
the best buy?
A. The 9 oz pk. B. The 16 oz pk. C. The 24 oz pk. D. None
Answers
The solution is Option C.
The package of 24 ounce is the best buy because the unit rate per ounce is given by the equation C = $ 0.30
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the unit rate of the package = A
a)
A 9-ounce package costs $2.79
So , the cost of 1 ounce = 2.79 / 9
On simplifying the equation , we get
The cost of 1 ounce A = $ 0.31
b)
A 16-ounce package costs $5.12
So , the cost of 1 ounce = 5.12 / 16
On simplifying the equation , we get
The cost of 1 ounce B = $ 0.32
c)
A 24-ounce package costs $7.20
So , the cost of 1 ounce = 7.20 / 24
On simplifying the equation , we get
The cost of 1 ounce C = $ 0.30
Now , $ 0.30 < $ 0.31 < $ 0.32
Hence , the best package is the 24 ounce package which costs $ 7.20

B) Fifteen sixteenths
C) Seventeen sixteenths
D) Eighteen sixteenths
Answers
Answer:
A) 14/16
Step-by-step explanation:
To solve 1 3/4 x 2/4, we need to:
Make 1 3/4 an improper fraction:
1 = 4/4, 4/4 + 3/4 = 7/4
Simplify 2/4:
2/4 = 1/2
Multiply Numerators:
7 x 1 = 7
Multiply Denominators:
4 x 2 = 8
Since the answer to 1 3/4 x 2/4 is 7/8, we know that 7/8 = 14/16.
Therefore, your answer is A) 14/16.

Some events cannot be predicted with certainty, but we can determine how likely they are. The probability of an event is a measure of the likelihood that the event will take place.
Let’s take flipping a coin as an example. When the coin is flipped, there are two possible results, or outcomes—heads or tails. All possible outcomes of an event are called the event’s sample space, and the number of outcomes in the sample space is the sample size. In the event of flipping a coin, the sample space is {heads, tails} and the sample size is 2.
The probability of an event is represented as a fraction. The numerator of the fraction is the number of times an event occurs, and the denominator is the sample size.
Let’s find the probability of getting heads when a coin is flipped. A coin has two sides, and one of them is heads. So, the number of ways the event occurs is 1, and the number of possible outcomes is 2.
The probability of getting heads is (1/2), or 0.5. What do you think the probability of getting tails is? Why?
Now consider a different event, rolling a die. What is the probability of rolling a two on a die? What is the probability of rolling a multiple of two?
Answers
Answer:
the probability of getting tails is 1/2 the same reason as of heads
probability of 2 on a die: 1/6, multiple of 2: 1/2
Step-by-step explanation:
The numbers that can appear on a dice are:
{1,2,3,4,5,6}, so if we want 2 only there is only one in the outcomes so 1/6
now if we want multiples of 2 there are 3 of them in the outcomes {2,4,6}
so the probability 3/6 = 1/2
Answer:
Step-by-step explanation:
The two outcomes of the toss of a coin are heads or tails. For any individual toss of the coin, the outcome will be either heads or tails.
