6p+ 1m= $9
⇒ 12p+ 2m= $18 (1)

4p+ 2m= $8 (2)

Take (1) -(2), we have:
(12p -4p)+ (2m -2m)= $18 -$8
⇒ 8p= $10
⇒ p= $10/8
⇒ p= $1.25

6p+ 1m= $9
⇒ 6*($1.25)+ m= $9
⇒ $7.5+ m= $9
⇒ m= $9 -$7.5
⇒ m= $1.50.

Final answer: p= $1.25, m= $1.50~

You can multiply 6p + m = 9 by -2 so you gonna have -12p - 2m = -18 then you can say : -12p - 2m = -18 ⇒ -8p = -10 ⇒ p = 10/8 ⇒ p = 1.25  
                 4p + 2m = 8 
so now you can find the m : 6 * 1.25 + m = 9 ⇒ 7.5 + m = 9 ⇒ m = 9 - 7.5 ⇒ m= 1.5 :)))
i hope this is helpful 
have a nice day

To make 1 1/2 dozen muffins, a recipe uses 3 1/2 cups of flour. How many cups of flour are needed for every dozen muffins made?

Ratio and proportion

convert to inproper fracton first

1 and 1/2=1+1/2=2/2+1/2=3/2

3 and 1/2=3+1/2=6/2+1/2=7/2


3/2dozen=7/2cups
times 2 both sides
3dozen=7cups
divide by 3 both sides
1dozen=7/3cups=2 and 1/3 cup

The cost to produce q items is C(q)=1300+2q2 dollars. Find the marginal cost of producing the 12th item. Interpret your answer i
Ad libitum [116K]

Answer: Marginal cost = $46

The cost of production increases by about $46 when one additional unit is produced.

Step-by-step explanation:

Given : The cost to produce q items is C(q)=1300+2q^2 dollars.

C(12)=1300+2(12)^2=1588\\\\ C(11)=1300+2(11)^2=1542

The marginal cost of producing the 12th item= C(12)-C(11)

=1588-1542=46

Interpretation : It means , the cost of production increases by about $46 when one additional unit is produced.

The boy wants to build rectangular beetle cages to study beetle behavior. He wants all the sides on the base of his cages to be
kap26 [50]

Answer:

32 cm by 18 cm

16 cm by 36 cm,

48 cm by 12 cm

24 cm by 24 cm

Step-by-step explanation:

<u><em>The complete question is</em></u>

A boy wants to build rectangular cages. He wants all the sides on the base of his cages to beat least 10 cm long.he also wants the base area to equal 576 cm2. The boy needs help to find all the possible lengths and widths for the base of the cages. He used only whole centimeters, with no fractional parts.what are all the possible dimensions for the rectangular base?

we know that

The number 576 decompose in prime factors is the same that write

576=(2^6)(3^2)

To find out possible side lengths, multiply different combinations of these prime numbers together (make sure each pair adds up to 10)

3x3=9cm                  2x2x2x2x2x2= 64cm  ----> is not a combination (one side is not greater than 10)

3x3x2= 18cm            2x2x2x2x2= 32cm

3x3x2x2= 36cm        2x2x2x2= 16cm

3x2x2= 12cm             3x2x2x2x2= 48cm

3x2x2x2= 24cm         3x2x2x2= 24cm

therefore

32 cm by 18 cm

16 cm by 36 cm,

48 cm by 12 cm

24 cm by 24 cm
