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

Answer:

Julie's share of the profits is (6/16)($4000) = $1500

Step-by-step explanation:

Write and solve an equation of ratios:

Jane's contrib.      $10000        10

---------------------- = -------------- = ------ .

Julie's contrib.         $6000        6

Adding 10 and 6 together, we get 16.

Julie's share of the profits is (6/16)($4000) = $1500.  Jane would take (10/16)($4000), or $2500.

Solve the equation there is no solution right no solution 4 x+1/3=20
Dmitrij [34]
If the equation is 4x+1/3=20, your answer would be x=59/12.
- You would subtract 1/3 from each side. (1/3 - 1/3) (20-1/3)
- Then your new equation would be 4x = 59/3
- You would divide 4 from each side (4/4) (59/3 / 4)
- x = 59/12

I = Prt
Olegator [25]

Answer:

r=3.5\%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$1,200\\ I=\$210\\r=?

substitute in the formula above

210=1,200(5r)

solve for r

r=210/6,000

r=0.035

convert to percentage (multiply by 100)

r=3.5\%
