4c+c+5c = 5c+5c= 10c
I added the single c to the 4c first to get another 5c then added the two 5c together to get 10c, since all terms have a single c in them all can be combined
Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
(4) 64 tiles, (5) 
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft
= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 
So, the expression is .
(6) The equivalent expression is 
.
Answer:
168 miles
Step-by-step explanation:
If he uses 5 gallons to drive 140 miles, that means that he can drive 24 miles for every gallon (140/5=24)
7 times 24 is 168 so he can drive 168 miles on 7 gallons of gas
Answer:
-4 and 2
Step-by-step explanation:
the graph intersects the x-axis only at the points (-4,0) and (2,0) so the only zeroes of the graph are going to be -2 and 2
