Answer:
x = 2
Step-by-step explanation:
1 - 3x = -5
Subtract 1 from each side
1-3x-1 = -5-1
-3x = -6
Divide each side by -3
-3x/-3 = -6/-3
x = 2
Answer:
50?
Step-by-step explanation:
8+12+27=50
1+3+4=8
The nearest hundred will be in the hundredth place
For example, 2000
2 is in the thousands, followed by hundreds, ten, ones
to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.
So in this case 678 will equal 700
Example: if it were 644, then it would be 600
hope this helps
Set up an system:
x+y=52
x=y-2
Substitute in:
(y-2)+y=52
2y-2=52
2y=54
y=27
27-2=25
The answers are 27 and 25
Answer:
3x+15
Step-by-step explanation:
When it says "the sum of a number three times", it means 3x, because the x stands for multiplication and the problem says the sum sum is between 3x and the number 15. So your equation is 3x+15. Hope this helps ;)
