what is 9 1/2 + (-4.0) .Please show work. (ps. it can be in fraction or decimal form)

Answers

Answer 1

Answer:

5 1/2

Step-by-step explanation:

Answer 2

Answer:

5 1/2

Step-by-step explanation:

so since nine is the whole number part of "9 1/2" you can easily subtract 4 from if (bc it's another whole number) but the confusing part of this problem is the "+(-4)" the parentheses are just so you don't mix up the + and -, but regardless, when you add a negative number it's the same as subtracting.

9 1/2

-4

-----------

-5 1/2

* bring down the 1/2 :)

Answer:

[tex]\frac{7^{18}}{7^{9}}[/tex], (7³)³ and [tex]7^{4}*7^{5}[/tex]

Step-by-step explanation:

[tex]7^{8}*7[/tex]  = [tex]7^{9}[/tex] is equivalent to the following exponential expressions:

[tex]\frac{7^{18}}{7^{9}}[/tex], as it applies to the Quotient Rule of Exponents: [tex]\frac{a^{m}}{a^{n}} = a^{m-n}[/tex]. Therefore, you're essentially subtracting the exponents, resulting into [tex]7^{9}[/tex].

(7³)³: The Power-to-Power Rule of Exponents apply in this situation:[tex](a^{m})^{n} = a^{mn}[/tex]. Multiplying the exponent inside the parenthesis by the exponent outside the parenthesis results in an exponent of 9.

[tex]7^{4}*7^{5}[/tex]: the Product Rule of Exponents apply in this situation: [tex]a^{m}*a^{n} = a^{m+n}[/tex]. Adding the exponents of 4 to 5 results in an exponent of 9.

Answers

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180°

So (x + 10) + (2x + 20) + (2x - 5) = 180

x + 10 + 2x + 20 + 2x - 5 = 180

5x + 25 = 180

There were 56 runners to start a race. In the first half of the race, h of them dropped out. In the second half of the race, z of the remaining runners dropped
out. How many runners finished the race?

Answers

Answer:

56-h-z runners

Step-by-step explanation:

The only number we're given is 56, so the only thing that we can do is create an expression

Answer:

56 - h - z

Step-by-step explanation:

-h - z is the number of people who dropped out at any time in the race.

56 is the total amount, and you put -h - z behind it.

Therefore, you get 56 - h - z.

A.5 1/2 hours
b. 3 5/6 hours
c. 3 1/6 hours
d. 4 1/6 hours

Answers

Answer:

[tex]4\frac{1}{6}[/tex] hours

Step-by-step explanation:

Substract total hours from hours Cai spent driving to find how long he was at work.

[tex]4\frac{2}{3}[/tex] - [tex]\frac{5}{6}[/tex] = ?

Substract the second expression [tex]\frac{2}{3} - \frac{5}{6}[/tex] by the first expression 4.

[tex]\frac{25}{6}[/tex]

Convert to a mixed number.

[tex]4\frac{1}{6}[/tex]

Therefore, the answer is [tex]4\frac{1}{6}[/tex] hours.

Given the relation {(2, 3), (-2, 2), (1, 5), (0, -1)}, state the domain.

A. {-1, -2, 2, 3}

B. {-2, 0, 1, 2}

C. {-1, 0, 1, 2}

D. {-2, -1, 0, 3}

Answers

Answer:

C.{-1,0,1,2}

Step-by-step explanation:

B is the correct answer. The domain is the set of x-coordinates within the function; it shows how far left or right the function on the x-axis.

The Domain of the function is {-2, 0, 1, 2}. These are the x-coordinates contained within the function. They are in numerical order. The first x-coordinate shows how far left the function is to the x-axis (-2) and the last right coordinate (2) shows how far right the function is to the x-axis.

So, your answer is B.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

5 + 23 + 18 x (8 - 4) = 100

Simplify the expression, then we have

5 + 23 + 18 x (8 - 4) = 100

5 + 23 + 18 x 4 = 100

28 + 72 = 100

100 = 100

The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.
