Step 2:Let the number of adult camels = 6x .

Step 3:Let the number of baby camels = 5x

Step 4:It is given that the total number of adult camels and baby camels is 44 at the zoo. So According to the questions,

⇒6x+5x=44

⇒11x=44

⇒x=44/11

⇒x=4

∴The number of adult camels = 6×4

                                               = 24

The inequality to find the scores she must make on the final exam to pass the course with an average of 77 or higher is (310 + x) / 5 >= 77.

The meaning is that she should have a score of 75 or higher to pass.

From the information, Shureka washburn has scores of 69,80,71, and 90 on her algebra tests and she must make on the final exam to pass the course with an average of 77 or higher.

Therefore, the inequality to express the information will be:

(69 + 80 + 71 + 90 + x)/5 >= 77

(310 + x) / 5 >= 77

Crops multiply

310 + x >= 77 × 5

310 + x >= 385

x >= 385 - 310

x >= 75

60 number of packages needed to have the same number of hamburgers and buns.

In this problem, we are using the concept of Least Common Multiple. The least common multiple (LCM) of two numberts is the smallest number that can be partitioned by both numbers. To have the same number of  buns and hamburgers, we just need to  calculate the least common multiple of 20 and 12

12's Multiples = 12, 24, 36, 48, 60, 72, 90

20's Multiples = 20, 40, 60, 80, 100

Here we can see the common multiple of 20 and 12 is 60, and the LCM of 20 and 12 is 60. Therefore they need to buy  60 packages in order to have the same number of hamburgers and buns

Step-by-step explanation:

    Number of problems done, and the time taken to finish them are in proportion.

Let the time taken to finish 40 problems = 'x'

30 : 45 = 40 : x

Product of extremes = 30 *x = 30x

Product of means = 45 * 40

Product of extremes = Product of means

                30 *x    = 45 * 40

The price in which Evan bought the car for in 2008 is 75 percentage or £14000

What is Percentage ?

Percentage (%), which is a relative figure used to denote hundredths of any quantity. One percent is represented by the symbol 1%; hence, 100 percent denotes the entire amount, and 200 percent designates double the amount.

Given,

Loss% = 25%

Profit% = 45%

selling price = £15,225

The price of the car before getting the profit of 45%

= 15225 / 145 x 100

= 105 x 100

= 10500

The price of the car before getting the profit of 45% is  £10500

Now, he had a loss of 25%

=100% - 25%

= 75%

So, the price will be

= 10500 / 75 x 100

= 14000

Hence, Evan bought the car for £14000 in 2008

3x - y = -7 is the required equation of the line, which will bisect the line segment with endpoints (-7, 6) and (5,2).

the equation for the perpendicular bisector of the line  with end points [tex](x_{0},y_{0})\\[/tex] and [tex](x_{1},y_{1})[/tex] are given by:

[tex]2(x_{1} - x_{0})x+2(y_{1}-y_{0})y = x^{2} _{1}-x^{2} _{0}+y^{2}_{1}-y^{2}_{0}[/tex]

in the given case we have,

[tex](x_{0},y_{0})\\[/tex] = (-7,6)

and

[tex](x_{1},y_{1})[/tex] = (5,2)

now substituting the given values in the above equation we get,

2(5-(-7))x + 2(2-6)y = 5²- (-7)² + 2²- 6²

= 24x - 8y = 25 - 49 + 4 - 36

The change in temperature is the difference between the two temperatures. In our case this is 25 F - (-8F) = 33 F. Notice that the subtracting the negative number changes the sign of the operation and turns it into an addition problem25 F+ 8 F = 33 F.

∠ AEC = ∠ DEB by using the property of the straight lines.

We are given the two lines AB and CD.

We are given that they intersect at point E and both are the straight lines.

Now, we know that, the sum of angles of a straight line will be equal to 180° (straight line property).

Now, For line AB, we get that:

∠ AED + ∠ DEB = 180°    …(1)

For line CD, we get that,

∠AED + ∠ AEC = 180°   … (2)

Now, we will subtract (1) from (2) and we get that:

∠ AED + ∠ DEB - ∠AED - ∠ AEC = 180° - 180°

∠ DEB - ∠ AEC = 0

∠ DEB = ∠ AEC

∠ AEC = ∠ DEB

Hence proved.

Therefore, we get that, ∠ AEC = ∠ DEB by using the property of the straight lines.

Given the information on the problem, we can use the law of cosines to find the length of p with the following equation:

substituting the values at hand, we get the following:

therefore, the length of p is 111 cm

True.

Given the statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

For the given question,

The distance from 0 to x on a number line is greater than 5

We write the above statement in mathematical expression form as,

⇒ |x - 0| > 5

⇒ |x| > 5

⇒ x > 5  

We need to determine the value of an expression -5 + x

From (1),

⇒ x > 5  

Subtract -5 from both sides,

⇒ -5 + x = -5 + 5

⇒ -5 + x > 0

From the above expression, we observe that the value of the expression is always greater than 1.

This means the value of an expression -5 + x is positive.

Therefore, the given statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

In mathematics, a number line can be described as a figure that symbolizes numbers on a consecutive line. The digits on a number line are positioned successively with equal spacing along its length. It can be infinitely expanded in any direction and is often depicted horizontally.

Absolute value is the distance between a digit and zero on a number line. Since the space is forever positive, the absolute value will always be positive.

Answer: N > -4

Step-by-step explanation:

Cuz It's Right

The solution for inequality  is n < -4.

The given inequality is −2(n − 3.5) > 15

An inequality will have the sign < , > , ≥ or ≤ instead of an equality in an equation. That is, an inequality compares two quantities on either sides of the inequality sign.

We are asked to solve the inequality  −2(n − 3.5) > 15. That is, to find the possible values for n.

−2(n − 3.5) > 15

Dividing throughout by 2,

-(n - 3.5) > 15/2

⇒ -n +3.5 > 7.5

Subtracting 3.5 from both sides,

⇒ -n > 7.5 - 3.5

⇒ -n > 4

Multiply -1 on both sides of the inequality and the inequality will be reversed,

⇒ n < -4 is the solution for n.

The solution is the values of n less than -4.
