So, to find the number of seats already replaced:
5 x 236 = 1180
1 x 348 = 348
1190 + 348 = 1528
So 1528 seats have been replaced.
3000 - 1528 = 1472
And 1472 seats still need to be replaced.
Bc they all contain 5 but different place values
Answer:
36 in because the radius×2=diameter
Step-by-step explanation:
Answer:
C) -5/12
Step-by-step explanation:
To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.
x's:-9-3=-12
y's:-1-(-6)=5
Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.
The number is xy
x+y=12
10y+x=54+10x+y
so
x+y=12
minus x both sides
y=12-x
sub that for y
10(12-x)+x=54+10x+(12-x)
120-10x+x=54+10x+12-x
120-9x=66+9x
add 9x both sides
120=66+18x
minus 66 both sides
54=18x
divide both sides by 18
3=x
sub back
y=12-x
y=12-3
y=9
the number is 39
