2(5 - 3) = 10 - 6
-7 + (19 + 5) = (-7 + 19) + 5
11 + (6 + 8) = 11 + (28 + 6)
· 3 = 1

Answer:

Number of terms = 3

Degree = 6

Step-by-step explanation:

A polynomial is a mathematical expression that gives the detailed combination of variables with their coefficients, their positive exponential, and other variables using the operations of subtraction, addition, and multiplication

The number of terms in a polynomial is the number of different powers of added or subtracted in the expression

Therefore, the number of terms in the expression -3·s⁶ + 2·s⁴ + 3·s³ is 3 terms

Number of terms = 3

The degree of a polynomial is given by the highest power of the variables in the polynomial. Therefore, the degree of the given polynomial is 6

Degree = 6

Answer:

The total comission on the sale was $375.

Step-by-step explanation:

Since the salesperson sold the car for $12,300, the total comission on the sale would be equal to the 5% of $10,000 plus the 3% of the remaining amount which would be:

Total comission=(10,000*5%)+(12,500-10000)*(3%)

Total comission=500+(2,500*3%)

Total comission=300+75

Total comission=375

According to this, the answer is that the total comission on the sale was $375.

Answer:

There is a difference between FRACTION and PROPORTION.

Explanation of fraction:

On a card board sheet draw a square or rectangle or any simple shape of your choice. Divide your preferred shape into 4 equal parts. One portion or one part of the divided shape is 1/4. Three (3 ) parts of the divided shape equal 3/4. Also if the shape is divided into twenty (20). One (1) part is 1/20, sixteen(16) parts equal 16/20.

Explanation of Proportion:

If an item is shared in a proportion of 3:4,it means that A gets 3/(3+4) of what is to be shared , that is 3/7 of the bulk item to be shared. B gets 4/(3+4) of what is to be shared, that is 4/7 of the bulk item to be shared.

Also if an item is shared in a proportion of 16:20 , A gets 16/(16+20)=16/36 of Bulk item while B gets 20/(16+20)= 20/36 of the Bulk item being shared.

In effect Fractions and Proportions are related but different.

Answer:

7, 24, 26

Step-by-step explanation:

6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)

Answer:

the amount left for gift c is $7.54

Step-by-step explanation:

The computation of the amount left for gift c is shown below:

= Total money to spend - spent on gift A - spent on gift B

= $20 - $8.34 - $4.12

= $20 - $12.46

= $7.54

Hence, the amount left for gift c is $7.54

Answer:

second table

Step-by-step explanation:

For a proportional relationship, the constant of proportionality k is

k = [tex]\frac{y}{x}[/tex]

Choose an ordered pair from each table and evaluate for k

Table 1

using (8, 1 ), then

k = [tex]\frac{1}{8}[/tex] = 0.125 ≠ 0.8

Table 2

using (10, 8 ), then

k = [tex]\frac{8}{10}[/tex] = 0.8

Table 3

using (8, 0.8 ), then

k = [tex]\frac{0.8}{8}[/tex] = 0.1 ≠ 0.8

Table 4

using (10, 20.8 ), then

k = [tex]\frac{20.8}{10}[/tex] = 2.08 ≠ 0.8

Table 2 has a constant of proportionality k = 0.8

Answer:

x=1

Step-by-step explanation:

(5x-3)3=8

taking the cube of both sides we get

5x-3=2

adding three to both sides we get

5x=5

dividing by five on both sides we get

x=1

FACTS TO KNOW BEFORE SOLVING :-

__________________________________________________________

[tex]4 \times 8^{2x+1} = 32^{x+2}[/tex]

Lets express it in terms of 2.

[tex]=> 2^2 \times 2^{3 (2x+1)} = 2^{5(x+2)}[/tex]

[tex]=> 2^2 \times 2^{6x+3} = 2^{5x+10}[/tex]

[tex]=> 2^{2 + 6x+3} = 2^{5x+10}[/tex]

[tex]=> 2^{6x+5} = 2^{5x+10}[/tex]

Here the bases on both the sides are equal. Hence ,

[tex]=> 6x + 5 = 5x + 10[/tex]

[tex]=> 6x - 5x = 10 - 5[/tex]

[tex]=> x = 5[/tex]

(answer choices are in order btw) Answer choices:

Answer:

x-y=5

4x+6y=120

Step-by-step explanation:

let x = # of 4-point questions

ley y = # of 6-point questions

# of 4-point questions is 5 more than # of 6-point questions

x=y+5 or x-y=5

now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:

4x+6y=120

The System of Equation is

x-y=5

4x+6y=120

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let x be number of 4-point questions.

ley y be number of 6-point questions.

as, the 4-point questions is 5 more than 6-point questions

So, x=y+5

or x-y=5.................(1)

Since each x is worth 4 points and each y is worth 6 points, they total number of points is 120.

So, 4x+6y=120....................(2)

Answer:

3 percent

Step-by-step explanation:

convert to seconds

960 seconds to 930 seconds

30 seconds ÷ 960=3 per cent

The percentage reduction in time is required.

The percentage reduction is [tex]3.125\%[/tex]

The initial value of time = 16 minutes

Final value of time = 15 minutes and 30 seconds = 15.5 minutes

Percentage reduction is given by
