12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.
For this case we have the following system of equations:
We multiply the first equation by -1:
We have the following equivalent system:
We add the equations:
Equality is not fulfilled, so the system of equations has no solution.
Answer:
Option C
Let's solve your equation step-by-step
16.8-(-23.72)-31.3=x
Step 1:simplify both sides of the equation
16.8-(-23.72)-31.3=x
16.8+23.72+-31.3=x
(16.8+23.72+-31.3)=x (combine like terms)
9.22=x
9.22=x
Step 2: flip the equation
Answer: x=9.22
Answer:10
Step-by-step explanation:
if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15
Answer:
A) m < -175/k and B) 3c/5 - 11
Step-by-step explanation:
A) Add 90 to both sides. -mk > 175.
Next, divide both sides by -k. Because you divide by a negative, don't forget to reverse the sign!
m < -175/k.
B) Subtract 3c from both sides.
-5f = 55 - 3c.
Now multiply both sides by -1/5.
f = 3c/5 - 11
