Answer:

$25 = $6.50d

Step-by-step explanation:

Since d represents the amount of boxes of donuts, you would need to multiply d in the equation by 6.5 or $6.50 since the problem states that 1 dozen donuts costs $6.50 (assuming 1 box contains 1 dozen donuts). $6.50d would have to equate or equal to $25 because the equation 25 = 6.5d shows the most amount of boxes of donuts Tucker could purchase with $25.

If you were wondering, Tucker could purchase up to 3 boxes donuts with $25.

Answer:

cost of 1 box = $6.50

total money =$25

he want $26 to buy 4 boxes

Cai left his house for work and was gone 4 2/3 hours. he spent a total of 5/6 hours driving to and from work and didnt go anywhere else. How long was he at work?

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.

The measures of the angles of a triangle are shown in the figure below. Solve for X.
75°
(7X+14)
49°

Answers

Answer;

x=6

Step-by-step explanation:

Step-by-step explanation:

Angle in a triangle is 180

75+ (7x+14) +49 =180

75+ 49+ (7x+14)= 180

124+ (7x+ 14) = 180

124+ 14 +7x= 180

138+7x = 180

7x =180- 138

7x=42

x= 6

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.

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.
