Answer:
4 (-1 + 2 x)
Step-by-step explanation:
Simplify the following:
9 x - (x + 4)
-(x + 4) = -x - 4:
9 x + -4 - x
Grouping like terms, 9 x - 4 - x = (9 x - x) - 4:
(9 x - x) - 4
9 x - x = 8 x:
8 x - 4
Factor 4 out of 8 x - 4:
Answer: 4 (-1 + 2 x)
Answer:
x = 2 * (y/5) feets
Step-by-step explanation:
Given that :
Actual dimension of mural = 15 feet by 8 feet
Scale drawing = 2 feet : 5 feet
2 feets on the scale drawing represents 5 feets of the actual drawing.
Drawing length (x)
Actual mural length (y)
x = 2 * (y/5) feets
Hence, dimension of scale drawing:
x = 2 * (15/5) ; x = 2 * (8/5)
x = 6 feets ; 3.2 feets
Answer:
8/15
Step-by-step explanation:
4x2=8
5x3=15
Answer: $432
Step-by-step explanation: 540 minus 20% is 432 so $540 minus 20% is $432
Answer: 9 m + 7 n - 6 mn + 4 m
Step-by-step explanation:
m + 3 n + 6 mn - 4 .... for this expression , it is already in its simplified form as we can not add any term together because they are not have the same variables.
9 m + 7 n - 6 mn + 4 ..... this also is already simplified
7 m - 9 n - 6 mn + 4 ..... the same thing with this
9 m + 7 n - 6 mn + 4 m .... this particular can still be further simplified because we have 9m and 4m having the same variable and we can therefore add them together , the simplified form of the expression will be
13m + 7n - 6mn
