There are many different types of equations we can use to allow x to equal 19! Below are some examples :) See if you can come up with some on your own based off of these examples:
5x = 95.....................................Divide both sides b 5
x = 19.......................................There's one for you :)
_____________________________________________________________
1 + x - 5 = 15............................Combine like terms
x - 4 = 15..................................Add 4 to both sides
x = 19
_____________________________________________________________
There's just a couple of examples, but see if you can come up with some on your own and let me know if you get stuck!
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D
Answer: a = -5
Step-by-step explanation:
First, open up the brackets, and solve it
-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)
bring the -8a to the left side, so that all the a’s are together
-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)
-12a + 8a = -22 + 42
solve
-4a = 20
divide -4 on both sides
a = -5
Answer:
143
Step-by-step explanation:
450-28= 422
422÷2.95= 143.05
round down to 143
Written explanation:
If her first card had $450 but she spent $28 that means she only has $422 left. In order to find out how many barrettes she can buy you divide the amount she has left by 2.95 and get roughly 143.05 barrettes, but you can't go over the budget so at the max Erin can only get 143 barrettes
Answer:
Expose both of left side and right side.
For example: on the left side: 2(x+6) = 2x + 6.
