(9×10^5)(6×10^-7) = 9×6×10^5×10^-7
=54×10^(5-7)
=54×10^-2
=0,54
Answer:
y = 25
Step-by-step explanation:
To find slope, we use this expression: 
Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.
=4
Simplify the denominator:
=4
Multiply both sides by 6 to isolate the y - 1: y - 1 = 24
Add 1 to both sides to isolate the y: y = 25
y = 25
Answer:
y= 3x-1
Step-by-step explanation:
Answer:
Your answer would be x+y=531 and y=2x
Step-by-step explanation:
We know that Nancy bought 531 shirts and that some are long sleeved and some are short sleeved. Since x represents the long sleeved shirts and y represents the short sleeved shirts, x+y=531. We also know that there are twice as many short sleeved shirts as long sleeved shirts. So, y=2x.
