The word in the problem that indicates that a negative sign should be used is "descend".

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

We know that he stops for water breaks four times, and between each water break, he descends 15 meters.

The written equation is:

4 x (-15)m = -60m

The negative sign is used because the hiker is descending, so its height is decreasing. The word in the problem that indicates that a negative sign should be used is "descend"

90/2.5 = 36

36 pages per hour

225 / 36 = 6.25 hours

Answer:

6.25 hours

Step-by-step explanation:

2 and half hours = 2.5 hours

Proportions:

90 pages  ⇔  2.5 hours

225 pages  ⇔  E hours

E = 225*2.5/90

E = 6.25 hours

Answer:

n + 32

Step-by-step explanation:

More than indicates you are adding. 32 more than n is shown by the expression n + 32.

The algebraic expression for 32 more than a number n is 32 + n where n is the real number.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

32 more than a number n

Here n is the real number.

As we know,

The linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

The expression can be written mathematically,

32 more than a number n = 32 + n

Thus, the algebraic expression for 32 more than a number n is 32 + n where n is the real number.

Answer:

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of its interior opposite angles.If any side of a triangle is extended, then the exterior angle so formed is the sum of the two opposite interior angles of the triangle. In the given figure, the side BC of angle ABC is extended.

They’re the same.

Give them common denominators by looking at their least common multiples. 6 and 21 are the denominators and they have to be the same to compare. Their least common multiple is 42.

So 1 4/6 will turn into 1 28/42. I know this because their least common multiple is 42. So I multiplied the 6 by 7 to get 42 as the denominator and you must also multiply the numerator by 6.

1 14/21 will need to be multiplied by 2 to get a denominator of 42. It will turn into 1 28/42. Both simplify down to 1 2/3.

Answer:

The are the same.

Step-by-step explanation:

Because both begin with a 1, ignore that for now.

You have 4/6 and 14/21. Do your best to reduce each. Think about a number that can go into each.

Start with 4/6. They are both even numbers, so 2. 4/2 =  2 and 6/2 = 3

so 4/6 can be reduced to 2/3.

14/21 is trickier, one is odd and the other is even, so no even number will work. 3 can't go in to 14, or 5, but 7 can, and cool! 7 can go in to 21 as well!

14/7 = 2   21/7 = 3    so 14/21 can be reduced to 2/3!

You can also use a common denominator, but you need a calculator for this problem. To solve that way you would take 4/6 and multiply by 21/21 and you would multiply 14/21 by 6/6, this way you'll end up with 126 on the bottom, and you'll see you get 84 on the top.

[tex]\frac{4}{6} * \frac{21}{21} = \frac{84}{124}[/tex]

[tex]\frac{14}{21} * \frac{6}{6} = \frac{84}{124}[/tex]

This is much harder without a calculator. Always try and reduce first, because if you end up having to find a common denominator, it will be smaller and more manageable.

Step-by-step explanation:

Use the function to find the coordinates of the endpoints.  Find the slope between those points, then use point-slope form to write the equation.  If you wish, you can simplify to slope-intercept form.

For example, #66:

f(2) = -4(2) + 1 = -7

f(5) = -4(5) + 1 = -19

So the endpoints of the secant line are (2, -7) and (5, -19).  The slope between those lines is:

m = (-19 − (-7)) / (5 − 2)

m = -12 / 3

m = -4

The equation of the line in point-slope form is:

y − (-7) = -4 (x − 2)

y + 7 = -4 (x − 2)

Simplifying:

y + 7 = -4x + 8

y = -4x + 1

f(x) is a line, so unsurprisingly, the secant line connecting two points on that line has the same equation.

Let's try #68:

g(2) = (-1)² + 1 = 2

g(5) = (2)² + 1 = 5

So the endpoints of the secant line are (-1, 2) and (2, 5).  The slope between those lines is:

m = (5 − 2) / (2 − (-1))

m = 3 / 3

m = 1

The equation of the line in point-slope form is:

y − 2 = 1 (x − (-1))

y − 2 = x + 1

Simplifying:

y = x + 3

[tex]0 \le d \le 2[/tex]

Graph with filled in circles at d = 0 and d = 2, shading in between

==========================================

Explanation:

d = amount downloaded in gigabytes

The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.

The largest amount allowed is d = 2. This is the cap that the ISP has set up.

So basically d can be anything between d = 0 and d = 2, including both endpoints. This means [tex]0 \le d \le 2[/tex]

We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.

Answer:

x = -15

Step-by-step explanation:

3x–7x=60

Combine like terms

-4x = 60

Divide by -4

-4x/-4 = 60/-4

x = -15

Answer:  x=-15

Step-by-step explanation:

3x -7x =60  

-4x = 60

x= -15  

Step-by-step explanation:

Hey, there!!

Let's simply work with it,

60° + 2x° + (2x+12)° = 180° { being a linear pair}.

or, 72° + 4x = 180°

4x = 180° - 70°

[tex]x = \frac{108}{4} [/tex]

Therefore, the value of x is 27°.

Now,

2x° = (2×27)°= 54°

(2x+12)° = 2×27°+12°= 66°.

(x+2)= 27+ 2= 29°

Now, The left angle is 27°.

Therefore, The answer is option A.

Answer: A & C & D

Step-by-step explanation:

The Angles which are in linear pairs are,

∠SRT and ∠TRV,

∠VRW and ∠WRS,

∠VRU and ∠URS.

When two lines meet at a single point, they form a linear pair of angles. After the intersection of the two lines, the angles are said to be linear if they are adjacent to one another. A linear pair's angles always add up to 180 degrees. Additional angles are another name for these angles. The angles with a common vertex are called the adjacent angles.

Given the figure and finding linear pair of angles,

The property of linear pair of angles says that the sum of two angles is 180⁰.

A: ∠SRT + ∠TRV = 180⁰

pair is linear

B:  ∠SRT + ∠TRU > 180⁰

pair is nonlinear

C: ∠VRW + ∠WRS  = 180⁰

pair is linear

D: ∠VRW + ∠URS = 180⁰

par is linear

E: ∠URW + ∠WRS < 180⁰

pair is nonlinear

Hence the linear pairs are (∠SRT and ∠TRV), (∠VRW and ∠WRS), and (∠VRW and ∠URS).
