What is the value of x and y in 8x equals 6y?
8x = 6y (8/6)x = y (4/3)x = y Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.
If y varies directly as x and y is 6 when x is 72 what is the value of y when x is 8?
y is 2/3.
How do you solve 2x plus y equals 8 y equals -x plus 5 substitution method?
2x+y = 8 y = -x+5 Substitute y for -x+5 into the first equation: 2x+(-x+5) = 8 2x-x+5 = 8 x = 8-5 x = 3 Substitute the value of x into the original equations to find the value of y: x = 3 and y = 2
What is six eighths in a percentage how did you get it?
By formula, x/y*100 = Percentage. 6/8*100 = 75% ie) The formula for percentile value is x/y *100 where X is the part of y for which percentage needs to be known, and Y is our standard. eg) What percent is is 3 of 8. 3 is our 'x' of which value needs to be known, 8, or 'Y' is our standard. 3/8*100 = 37.5%
What is value of the expression when x 5 and y -3?
8
Which value of x satisfies both -9x 4y 8 and -3x y 4 given the same value of y?
If you mean: -9x+4y = 8 and -3x+y = 4 then the solutions are x = -8/3 and y = -4
What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
if y = 5x – 8 find the value of x if y = 7?
if y = 5x – 8 find the value of x if y = 7
If 2 x y 7 what is the value of y when x 3?
if 2x + y = 7, what is the value of y when x = 3?
-x+ 4 y>-8 x+y8 y?
-x+ 4y>-8, x+y≤3 y≤3-x -x+4(3-x)>-8 -x+12-4x>-8 12-5x>-8 -5x>-20 x>4 y≤3-(4) y≤-1
What is it when Z varies directly with x and inversely with y When x 2 and y 4 z 3 What is the value of z when x 4 and y 9?
z = 8/3.
What is the value of x and y in this equation 5 x plus 8 y equals 3 and negative 4 x - 4 y equals negative 1?
x = -1/3 and y = 7/12
