-2z + 3
It is: 14z/28 = z/2 in its simplest form
It is an expression in two variables, z and t. It can be simplified to 14z + 2t or 2*(7z + t)
2(x - 3y + 7z)
Well that written out is 14z+8=12 so first you want to subtract 8 to get 14z=4. Now I. Order To make both sides equal, you have to divide by 14 on both sides. That leaves you with z=.28571429

Is the solution to 2x = 3x - 12 - 5x a positive or a negative integer? Explain( please don't copy this exactly, it is plagiarism, and you might lose some points for it) The solution to 2x = 2x - 12 - 5x is a negative integer because it is equal to -2.4 and that is a negative number.2x = 2x - 12 - 5x2x = -3x - 12 (combine like terms)5x = -12 (add 2x to each side)x = -2.4 (divide each side by 5)..................15. The sum of two consecutive integers is -45. What are they?(n) + (n-1) = -45 (write an equation) (( n equals number ))2n-1 = -45 (combine liek terms)2n = -44 (add 1 to each side)n = -22 (divide each side by 2)so your numbers are -22 and -23 because -22 - 1 (the n-1 part) is -23. To check, -22 + -23 = -45.........16. The sum of three consecutive integers is -255. What are they?(n) + (n-1) + (n-2) = -255 (write an equation)3n -3 = -255 (combine like terms)3n = -252 (add 3 to each side)n = -84 (divide each side by 3)so your numbers are -84, -85, and -86. You get the last two because of the (n-1) and the (n-2) and -84 - 1 is -85 and -84 - 2 is -86. To check: -84 + -85 + -86 = -255.You're welcome! Hope this helped!Questioner: Thanks so much my tutor explained this so weird but because you explained how you found the answer i get equations a lot better she had like 6 or 7 different steps. i corrected # 10

2 + 14z = -8 + 9zSubtract 9z from each side:2 + 5z = -8Subtract 2 from each side:5z = -10Divide each side by 5:z = -2
The LCM is: 98z
z = -1/7
14 oz is 1.75 cups
2x+5y+2z-3w=3 3x+6y+5z+2w=2 4x+5y+14z+14w=11
According to the specifications, it has a built-in 1.3 megapixel webcam.
