The solution to the equations are x = 3 and no solution in the set, respectively
How to solve the equations using the replacement sets?Question 1
The equation is given as:
5x - 6 = 9
The replacement set is given as
{0,1, 2, 3, 4}
So, we replace the variables using the elements in the replacement set
When x = 0, we have
5(0) - 6 = 9
- 6 = 9 -- false
When x = 1, we have
5(1) - 6 = 9
- 1 = 9 -- false
When x = 2, we have
5(2) - 6 = 9
4 = 9 -- false
When x = 3, we have
5(3) - 6 = 9
9 = 9 -- true
Hence, the value of the equation is x = 3
Question 1
The equation is given as:
8x + 4 = 5x - 6
The replacement set is given as
{2, 3, 4, 5}
So, we replace the variables using the elements in the replacement set
When x = 2, we have
8(2) + 4 = 5(2) - 6
20 = 4 -- false
When x = 3, we have
8(3) + 4 = 5(3) - 6
28 = 9 -- false
When x = 4, we have
8(3) + 4 = 5(4) - 6
28 = 14 -- false
When x = 5, we have
8(5) + 4 = 5(5) - 6
44 = 19 -- false
Hence, the value of the equation is not in the solution set

work out (7.3 x 10^5) + (4x 10^5) in standard index form
The sum written in standard index form is 1.13*10^6
How to add numbers in scientific notation?
So here we want to add two numbers that are written in scientific notation, these are:
(7.3*10^5) + (4*10^5)
Now we can take the factor "10^5" as a common factor, so we can write:
(7.3*10^5) + (4*10^5) = (7.3 + 4)*10^5 = 11.3*10^5
Now we want to write this in standard index form (this is scientific notation), so we can have only one decimal on the left side of the decimal point, then we can write this as:
11.3*10^5 = 1.13*10^6

Find the sum of the AP: 2,7,12 to 10 terms.
Answer:
Clearly, the given sequence is an AP with first term a=2, common difference d=5 and n=10.
Now,
s10 = 10/2 (2a + 10-1d)
=5(2x2+9x5)
=245
Step-by-step explanation:
Answer:
S₁₀ = 245
Step-by-step explanation:
the sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
here a₁ = 2 and d = a₂ - a₁ = 7 - 2 = 5 , then
S₁₀ = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ]
= 5(4 + 45)
= 5 × 49

Kyle played four rounds of golf. His scores were
72, 75, 68, and 84. If he would like an exact mean
of 74 for five rounds, what must he score on the
next round?
71
72
73
74
Answer:
71
Step-by-step explanation:
Mean is Average
You can Find the Mean of a set of numbers by adding them all up and then dividing that number by the amount of numbers in the set.
72 + 75 + 68 + 84 = 231
231 / 4 = 57.75
This is his current mean.
Let's add his next score.
72 + 75 + 68 + 84 + 71 = 370
Divide by 5 instead of 4 because we added another number to the data set.
370 / 5 = 74

The probabilities of randomly picking a green counter from three different bags are given below.
Order these bags from the lowest probability to the highest probability.
Answer:
Lowest to highest
7/10 , 11/15, 4/5
Step-by-step explanation:
Probably the easiest way to do this is to convert each of the fractions to decimals which will clearly indicate which is the highest and which the lowest etc.
4/5 = 0.80
11/15 = 0.73
7/10 = 0.7
0.7 is less than 0.73 is less than 0.80
So 7/10, 11/15, 4/5
However, I am assuming they want you to work with fractions
To compare fractions you have to get all the denominators equal and then compare the numerator
To get a common denominator find the Least Common Multiple of the denominators. This is the lowest number that can be divided by all three denominators
Looking at 5, 15 and 10 we can see that 30 is divisible by each denominator. So that becomes our common denominator
Now multiply each fraction denominator by a factor to make the denominator equal to the common denominator. At the same time multiply the numerator by the same factor
4/5 = (4 x 6) / (5 x 6) = 24/30 Highest
11/15 = (11 x 2) / (15 x 2) = 22/30
7/10 = (7 x 3) / (10 x 3) = 21/30 Lowest
Looking at the numerator alone we can see that 7/10 is the lowest, 11/15 is next lowest and 4/5 the highest

The numeric value of the expression 16 + 4(3q + p) when q = 6 and p = 2 is given by: 96.
How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value. This also works for multi-variable functions or expressions, as each instance of each variable will be replaced by their attributed values.
For this problem, the expression is given by:
16 + 4(3q + p)
The attributed values are given by:
q = 6, p = 2.
Hence the numeric value of the expression is found as follows:
16 + 4(3 x 6 + 2) = 16 + 4(18 + 2) = 16 + 4 x 20 = 16 + 80 = 96.

The correct option is (D) △ABC and △FED are not similar because the corresponding sides of the triangles are not in proportion.
What is the congruency of triangles?Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, rotate, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved.So, the two given triangles are:
△ABC and △DEF with no sides identical to the other.
Then, we can conclude that no congruency condition with a side statement is true.So, options (A) is (C) are incorrect.
∠B and ∠E do not seem to be identical.So, option (B) is also incorrect.
Since no sides are identical to each other then we can say that the given two triangles are not congruent when concluding that the answer to this problem is an option (D).
Therefore, the correct option is (D) △ABC and △FED are not similar because the corresponding sides of the triangles are not in proportion.

two cards are selected without replacement from a standard deck of 52 cards. what is the probability that both cards are the same color (either both black or both red)? round to three decimal places.
The probability of getting both the card with same color is 0.245
Total No. of cards in a deck = 52
The cards having the same color (either black or red ) = 26 out of 52
which is 26/52
The probability of finding a card having the same color without a replacement
P = 26/52 x 25/51
[∵ After taking one card, the total no . of cards will be 51 and the card having the same color is 25]
= 1/2 x 25/51
= 0.5 x 0.49
P = 0.245098
Therefore, the probability that both cards are the same color is 0.245098
We need to round off it to three decimals, Thus
