Answer:
It's C.
Step-by-step explanation:
12x+4+9x+8=180
Combine like terms 21x+12=180
Subtract 12 from both sides 21x=168
Divide each side by 21 21x/21=168/21
x=8
The answer is D because absolute value is always positive
Scientifict notation is (number greater than or equal to 1 and less than 10) times 10^x
count where the decima place would make the number less than 10 and more than or equal to 1
7 places
so move the decimal place to the left 7 places and put that as the x
1.52 times 10^7 is the answer

Answer:
58%
Step-by-step explanation:
The first thing that you have to do if figure out how many sandwiches are left we do this by the total - bad sandwiches = good sandwiches
12-5=7
There are 7 good sandwiches left. To figure out the percentage you do = now we fill in the parts the part is 7, the total is 12 and the % is x
= now we cross multiply, 7 x 100 and 12 x X
700=12x now we divide both sides by 12 so the x is alone
x = 58.33 now we round down because it ends in.3
x=58
