Answer:
the first step in solving an equation with a variable on each sides is to get the variable on one side. This is done by reversing the addition or subtraction of one of the terms with the variable.
Step-by-step explanation:
Answer:
37
Step-by-step explanation:
x = 1st number
y = 2st number
z = 3rd number
x + y + z = 235
y = x + 15
z = 8x
x + x + 15 + 8x = 235
10x = 220
x = 22
y = 37
z = 176
Answer:
139 windows
Step-by-step explanation:
you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours
Its the third one..........
f ( x ) = - 4x + 6
f ( 10 ) = - 4 ( 10 ) + 6
f ( 10 ) = - 40 + 6
f ( 10 ) = - 34
