2 and 5...................... hope I helped
Answer:
65
Step-by-step explanation:
I’m pretty sure it would be C
Well, first you'd have to get the x by it's self.
10x+1=3x+9
Subtract 3x from each side and you'll have the x on only one side rather than two.
7x+1=9
Now I'd get rid of the 1 on the x's side. So just subtract 1 from each side.
7x=8
Then you should make it so the seven isn't there with the x either. Just divide each side by 7.
Answer: x=8/7
Each time you change something on one side, you must do the same to the other side. T find the value of a variable in an equation, simple seclude it so it's on it's own without number to make things confusing.
The answer was x=8/7 btw.
Answer:
21,000
Step-by-step explanation:
front end estimation requires you to take the front / first digit of each number in this expression and round.
if you don't know how to round, basically you take the next digit after the first one, (in 719 you take the 1) and determine if that's below or above 5. If below, then keep the original first number. If above, add one more to the first digit. If the number is five itself, it is most common to round up (so add one).
like 425 would round to just 400; and 676 would round to 700.
multiply 700 and 30
youd get 21000
