C. [tex]l=\frac{4}{7} x[/tex]

Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Creating a system of equations thus :

Substitute for n and q

(q+3) + (q+6) + q = 36

3q + 9 = 36

3q = 36 - 9

q = 27 ÷ 3

q = 9 quarters

n = 9 + 3 = 12 nickels

d = 9 + 6 = 15 dimes

Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Answer:27

Step-by-step explanation:

3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27

Answer:

27

Step-by-step explanation:

First, you do what is inside the parantheses, so 11 - 5 is 6, then you multiply 1 x 2 = 2, and 3 x 6 is 18. Lastly, you add it all up and get the sum of 27. Hope this helps!

Answer:

it is non portional

Step-by-step explanation:

answer 32.395 pounds so 14.5 quarrs is 32.395 pounds

The approximate weight of 15.5 quarts of water will be 32.395 pounds.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a quart of water weighs about 2.09 pounds. The weight of the 15.5 quarts of water will be:-

1 quart = 2.09 pounds

15.5 quarts  = 15.5 x2.09

15.5 quarts = 39.395 pounds

Therefore, the approximate weight of 15.5 quarts of water will be 32.395 pounds.

Hello, It's me Moriah Elizabeth!

Answer:

1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.

2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.

3. Actual area is 17.2

Step-by-step explanation:

Answer:

1) 22

2)12

3)-80

4)-16

5)-10.5

6)-10

Step-by-step explanation:

-12x + 2y when x = -2 and y = -1

= -12 (-2) + 2 (-1)

= 24 + (-2)

= 22

10 + a - b when a = -4 and b = -6

= 10 + (-4) - (-6)

= 10 - 4 + 6

= 10 + 2

= 12

8(n-3) when n = -7

= 8 (- 7 - 3)

= - 56 - 24

= - 80

3 - x + 2(-x + 4) when x = 9

= 3 - 9 + 2 (- 9 + 4)

= - 6 - 18 + 8

= - 24 + 8

= - 16

12 - (15 + y) / 6 - 8 when y = -3

= 12 - 15 + 3 / 6 - 8

= 12 - 15 + 0.5 - 8

= - 3 - 7.5

= - 10.5

15 - a(-b) when a = 5 and b = -5

= 15 - 5 (5)

= 15 - 25

= - 10

4 1/12 + (-5 1/3)=

Eliminate the negative and change the operation.

=4 1/12 − 5 1/3

Rewrite your equation with the parts separated.

=4 + 1 1/2 − 5 − 1/3

Solve the whole numbers.

4−5= −1

Solve the fractions.

1 1/2 − 1/3=?

Find the LCD of 1/12 and 1/3 and rewrite to solve the equivalent fractions.  (Least Common Denominator)

LCD = 12

1 1/2 − 4 1/2= −3 1/2

Reduce the fraction, 3/12.

−3 1/2 = −1/4

Combine the whole and fraction.

−1 − 1/4= −1  and 1/4
