Answer:

8m/s

Explanation:

Given,

Distance covered (s) = 2.4 = 2.4 * 1000 = 2400m

Time taken (t) = 5 = 5 * 60 = 300

Now,

v = s/t

or, v * t = s

or, v * 2400 = 300

or, v = 2400/300

or, v = 8m/s

Answer:

x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Equate f(x) and g(x) , that is

- 3x + 4 = 2 ( subtract 4 from both sides )

- 3x = - 2 ( divide both sides by - 3 )

x = [tex]\frac{-2}{-3}[/tex] = [tex]\frac{2}{3}[/tex]

Answer: n=-30

Step-by-step explanation:

With what we are given in the description, we can find the missing number.

[tex]8+\frac{n}{3} =-2[/tex]

We get this equation because 8 is adding the quotient of a number and 3. A quotient of a number and 3 is written as [tex]\frac{n}{3}[/tex] because n is dividing 3. When that is added to 8, we get -2. With this equation, we can solve for n.

[tex]8+\frac{n}{3} =-2[/tex]           [subtract both sides by 8]

[tex]\frac{n}{3} =-10[/tex]                [multiply both sides by 3]

[tex]n=-30[/tex]

Now, we know that n=-30.

Answer:

3 chickens need 1 day to lay 3 eggs, because in 1.5 days 1 chicken lays 1.5 eggs

-> 1 day 1 chicken lays 1 egg so 3 chickens need 1 day to lay 3 eggs

study well !

Answer: 1 day

Explanation: Since one hen and a half plus one hen and a half is equal to 3 hens. And also one egg and a half plus one egg and a half equal to 3 eggs therefore also the time needed for three hens will be 2 times the time needed by one hen and a half

Answer:

Choice 3. -4x-3<13

Step-by-step explanation:

First, you will use process of elimination and cross out any obvious wrong answers. You can see that the symbol would not be flipped yet so the "<" would be pointing  to less than. That eliminates choice 1 and 4. Now, You can observe the 3rd step and see that -4x<16, to get that, you would need a "-4x" in the equation. Number 2 is 2x so that can't be right. Therefore, the answer is choice 3. This simple process of elimination and looking for clues will help you greatly in multiple choice problems instead of solving it the hard way.

Answer:

(0, - 2 ) and (3, 4 )

Step-by-step explanation:

Given the equations

3y = 2(x² - 3) , that is

3y = 2x² - 6 → (1)

2x - y = 2 (add y to both sides )

2x = 2 + y ( subtract 2 from both sides )

2x - 2 = y → (2)

Substitute y = 2x - 2 into (1)

3(2x - 2) = 2x² - 6

6x - 6 = 2x² - 6 ( subtract 6x - 6 from bpth sides )

0 = 2x² - 6x ( factor out 2x from each term )

0 = 2x(x - 3)

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

x - 3 = 0 ⇒ x = 3

Substitute these values into (2) for corresponding values of y

x = 0 : y = 2(0) - 2 = 0 - 2 = - 2 ⇒ (0, - 2 )

x = 3 : y = 2(3) - 2 = 6 - 2 = 4 ⇒ (3, 4 )

The value of p in the given equation 2 + p =4/5 + 3/5p is -5/2.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 2 + p =4/5 + 3/5p

Two plus p equal to four by five plus three by five times of p.

p is the variable in the given equation.

2 + p =4/5 + 3/5p

Take the variable terms on one side.

2-4/5 =3/5p-p

6/5= -2p/5

5=-2P

P=-5/2

Hence, the value of p in the given equation 2 + p =4/5 + 3/5p is -5/2.

Answer: A solution that results in a false statement when substituted back into the original equation.

Step-by-step explanation: An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.

The above question is based on Algebraic expressions. An algebraic expression is a mathematical expression which contains unknown variables represented by letters.

Our question above states that:

Cory earns $22 for every lawn he mows and $6 for every hedge he trims.

The Algebraic expression used to express the above statement is given to us in the question as :

22x + 6y

Where:

x = Number of lawns that he trims and

y = Number of hedges that he trims

Part A: Identify the coefficients and variables in the expression.

22x + 6y

i) The coefficients in this expression = 22 and 6. This is because a coefficient is always a number (Integer) that is multiplied by the unknown variable

ii) The variables in the above question = x and y. This is because variables are always represented by letters (alphabets)

Part B: How many terms are in the expression, what are they, and how do you know?

Terms are values which could be constants, variables or coefficients that make up an Algebraic expression.

There are two terms in the Algebraic expression = 22x + 6y and they are : 22x and 6y

Part 2: Which terms in the expression shows the total earned from mowing lawns?

Cory earns $22 for every lawn he mows

x = Number of lawns that he trims

Hence, the expression that shows the total earned from mowing lawns = $22 × x

= 22x

Here we have a problem with linear equations, we will find that:

A)The Coefficients are: 22 and 6

The variables are: x and y

B) The number of terms in the expression are two: 22x and 6y

2)Total earned for lawn mowing = 22x

Given that the expression 22x + 6y is used to keep track of Cory's earnings:

The Coefficient is a constant value in an equation which may be used to multiply a variable. In the scenario given, the coefficients are Cory's earning per lawn he mows and hedge he trims. The coefficient values are 22 and 6.

The variable in an expression represents values which can change or vary, in the scenario given, the number of lawns mowed or hedge trimmed may vary. Hence, the number of lawns and hedges are the variables.

The number of terms in the expression is 2:

The earning for lawn mowing.

The earning for hedge trimming.

Part 2:

Total earned from mowing lawns:

(earning per lawn mowed × number of lawns mowed)

(22 × x) = 22x

Answer:

aquatic environment is best fit

Answer:

Based on the data, there would likely be a very low amount of organisms performing aerobic cellular respiration at 1,000 meters as compared to the surface. This is due to the sudden drop in oxygen concentrations from 6 to 1.8 between 800-1,000 meters, while carbon dioxide increased from 44 ml/l to 49 ml/l.

The most beneficial adaptation for organisms based on the data would be anaerobic cellular respiration (without oxygen).

Step-by-step explanation:

Aerobic cellular respiration is a chemical process where oxygen is required to create energy from carbohydrates.

Answer:

Step-by-step explanation:

Width = w

triple the width = 3*w = 3w

Length = 7 yards longer than triple the width = 3w + 7

Perimeter = 438 yards

2*(length +width) = 438

2*(3w+ 7 + w) = 438       {Combine like terms}

2 * (4w + 7)     = 438

     2*4w +2*7 = 438       {Use distributive property}

         8w + 14 = 438          {Subtract 14 from both side}

                  8w = 438 - 14

                  8w = 424          {Divide both sides by 8}

                    w = 424/8

                     w = 53 yards

Length = 3*53 +7 = 159 + 7 = 166 yards

Width = 53 yards

Length = 166 yards
