[tex]2d+4d-9-7\\\\d =5[/tex]

Substitute ; d= 5 into the given equation

[tex]2(5)+4(5) -9-7\\\\Follow\:the\:PEMDAS\:order\:of\:operations\\\\10 +20 -9-7\\\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:\\\\10+20 =30\\\\=30-9-7\\\\30-9=21\\\\=21-7\\\\21-7\\=14[/tex]

The value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

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

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

The expression:

= 2d + 4d - 9 - 7

Plug d = 5 in the above expression:

= 2(5) + 4(5)- 9 - 7

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= 10 + 20 - 9 -7

= 30 - 16

= 14

Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

Step-by-step explanation:

The amount of sales tax charged on the repaired computer at Store A is 72 dollars.

We have to given that,

A 3-column table with 4 rows.

Column 1 has entries Computer repair, sales tax, gratuity, shipping.

Column 2 is labeled Store A with entries 1,200 dollars, 6 percent, 15 percent, Free.

Column 3 is labeled Store B with entries 1,350 dollars, 7 percent, 15 percent, 2 percent of total price.

Hence, For store A,

The amount of sales tax charged on the repaired computer at Store A is,

6% of 1200

= 6/100 x 1200

= 6 x 12

= 72 dollars

Therefore, the amount of sales tax charged on the repaired computer at Store A is 72 dollars.

add the weight of the bucket (.75) to the weight of the water (20.85) to get 21.6 pounds total

Answer:

First, convert 150% to the equivalent decimal 1.50 by dropping the percent sign and moving the decimal two places to the left. Then, multiply 9 by 1.50 to get 13.50. Maria now makes $13.50 per hour.

Step-by-step explanation:

I took the test and this is the sample answer

The required earnings for Maria for the three days is $78.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Maria babysat for 6 hours on Tuesday, 3 hours on Thursday, and 4 hours on Saturday, and paid $6.00 per hour.

Total earining = 6 × 6 + 3×6 + 4× 6
Total earning = 36 + 18 + 24
Total earning = $78

Thus, the required earnings of Maria for the three days is $78.

The cost of one ticket will be  £8.20

Explanation

Suppose, the cost of one ticket is  

As the offer says "buy 3 tickets and get a ticket free" , it means they actually need to pay for 3 tickets.

So, the total cost of 3 tickets  

Each of four friends pay £6.15 , so the total amount they pay  

=£6.15*4=£24.60

Thus, the equation will be .....

=3x=24.60

=x=24.60/3=8.20

 So, the cost of one ticket will be  £8.20

Answer: Choice A) $0.20

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

Explanation:

The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.

Divide this over 250 to get 50/250 = 0.20 dollars.

Their profit is $0.20 per pastry (ie 20 cents per pastry).

-------

You can think of it like this

50 dollar profit = 250 pastries

50/250 dollar profit = 250/250 pastries (dividing both sides by 250)

0.20 dollar profit = 1 pastry

That last equation tells us one pastry yields a profit of $0.20 or 20 cents.

Answer:

$0.20

Step-by-step explanation:

If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:

$100=250

    ?  = 1

1×100/250 = $0.40 ( at purchase)

Then when resold, the profit is:

if 250 pastries= $150

1 pastry=?

$150× 1/ 250= $0.60

s0, the profit will be $0.60 - $0.40 = $0.20

Answer:

L = 2w  134 = 2L + 2w

l= length

w=width

l=2w

P=Perimeter= 134 ft

P= 2(l+w)

 = 2(2w+w)

 = 2(3w) = 6w=134

w=134/6=22 1/3 ft

l= 2w = 2 x 22 1/3 = 44 2/3 ft

Answer: 26

Step-by-step explanation:

x is equal to 4 so we will input 4 into the expression for x and solve.

2(4)^2 - 3(4) + 6

2(16) - 12 + 6

32 - 12 + 6

32 - 6 = 26

I remember doing the last question.

If you recall, x = 29

Just plug 29 into x for each angle

A = 3(29) = 87

B = 2(29) + 1 = 59

C = 29 + 5 = 34

Answer:

The value of angle C is 34°

Step-by-step explanation:

2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}

or, 6x + 6° = 180°

or, 6x = 180° - 6°

or, x = 174°/6

or, x = 29°

now,

value of angle C = x+5°

= 29°+5°

= 34°
