Answer:
x = 9
Step-by-step explanation:
1) Subsitute! You have to replace y with 2x - 2 in 3x -y = 7, b/c they already gave you the equation for y (in the second part: y = 2x - 2)
So, your equation would look like this : 3x - (2x - 2) = 7
3) Solve suing PEMDAS!
There's a negative outside the parenthesis of 2x -2 -> - (2x-2). Multiply the negative individually inside the parenthesis so you will get (-2x + 2)
3x - 2x - 2 = 7 subtract the same variable; x
1x - 2 = 7 you don't need to put 1 to x, only if you want!
+ 2 + 2 add 2 on both sides
x = 9
Well, you just have to take what I said before:
1=ones digit
3=tens digit
8=hundreds digit
2=thousands digit
7=ten thousands digit
6=ten thousands digit
So like previous answers, you just look at the digit after the one being asked
So look at the thousands place. 2,831 or 2,000 since all numbers after that digit is irrelevant
Is 2,000 or 2,831 over the halfway point to 10,000? The halfway point being 5,000
No, it is not so that means 2,831 is closer to 670,000 rather than 680,000
Answer: 672,831 rounded to the nearest ten thousand IS 670,000
Answer:
67
Step-by-step explanation:
If the Work is shown
step by step I got the answer as 67. Don't know how to explain.
If you solve the inequality the result is
4x - 3 <u>></u> 5<u>
</u> +3 +3
_________
4x <u>></u> 8 Now divide both sides by 4
x <u>></u> 2 Is the result of solving the inequality
Your solution set is all real numbers 2 and greater
Therefore, C {2,3,4) is your solution set
