Answer: maybe 75 cents

Step-by-step explanation:

Answer:

The cost of a candy bar is $0.75.

Step-by-step explanation:

With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'

--Intially, determine the quotient of 1.70 and the two quantities.

+ Result should be 0.85

Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.

------------------------- Although, we are not done. -----------------------------------

Let's take the second sentence into account.

"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"

Determine the sum of .75 and (.85*2)

Alert: .75 came from subtracting 10 from the intial .85

Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.

Answer: B is Cheaper

Step-by-step explanation: Pic is attached. It is the initial price plus the money they charge per hour, multiplied by hour. From there it is just plugging in 7 for the hour. Hope this helps!

Company B would be cheaper than Company A for 7 hours of landscaping.

Two or more expressions with an equal sign are defined as an equation.

Given that, Company charges $35 per hour and a $250 equipment fee while Company B charges $25 per hour and a $300 equipment fee.

The amount charged by Company A for t hours of landscaping is:

A = 35t + 250      (1)

Similarly, the amount charged by Company B for t hours of landscaping is:

B = 25t + 300      (2)

Now, solve equation (1) for t = 7:

A = 35 (7) + 250

A = 245 + 250

A = 495

Hence, company A would charge $495 for 7 hours of landscaping.

Similarly, solving equation (2) for t = 7:

B = 25(7) + 300

B = 175 + 300

B = 475

Hence, company B would charge $475 for 7 hours of landscaping.

Therefore, Company B would be cheaper than Company A for 7 hours of landscaping.

The total amount that the consumer had to pay for both products was $ 94.50.

Step-by-step explanation:

Given that Mal sold a large photo for $ 50 and a large frame for $ 40, and that the sales tax for these products is 5%, to determine the total amount that the consumer had to pay to purchase these products arises from the following calculation:

(50 + 40) x 1.05 = X

90 x 1.05 = X

94.5 = X

Therefore, the total amount that the consumer had to pay for both products was $ 94.50.

Answer:

1. Evaluate the expression: $4.50

2. Expand the expression: 2.5 + 2 = 4.5 (4.50)

3. Total tax is 4.50. yes, both the evaluating and expanding got me the same answer.

4. Expanded Expression

Answer:

20cm, 28cm, 40cm

Step-by-step explanation:

Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.

4x + 7x + 10x = 105

21x = 105

x = 105 ÷ 21

x = 5

Shortest side (4x) = 5 × 4

Shortest side (4x) = 20

Middle side (7x) = 7 × 4

Middle side (7x) = 28

Longest side (10x) = 10 × 4

Longest side (10x) = 40

[tex]k(x,y) --> k'(x,y-7)[/tex]

Step-by-step explanation:

Given

[tex]k = (-3,4)[/tex]

Translation: 7 units down

Required

Determine the rule to produce k'

When an (x,y) coordinate is translated down by h units, the resulting point is:

(x,y) --> (x, y - h)

In this case:

[tex]h = 7[/tex]

So, we have:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Hence, option A answers the question.

Solving further to determine the coordinates of k'.

[tex]k = (-3,4)[/tex]

[tex]k' = (-3,4-7)[/tex]

[tex]k' = (-3,-3)[/tex]
