Multiply 340 by 20%
first change 20% into a decimal which is 0.2
340*0.2 = 68
so it decreased by 68.
The greatest common factor is 1 because there is not a number that goes into or will multiply and get 49 and 4. 49 is an odd number and 4 is an even number so the GCF is 1.
8 x 0.001 - 2 x 0.00001
= 0.008-0.00002
= 0.00798
Area=1/2 times base times height
base=4
height=3
area=1/2 times 4 times 3
area=2 times 3
area=6 square units
Step-by-step explanation:
Let
b=number of two storey houses,
t=number of three storey houses,
the total number of stories on Algebra Avenue is 95 more than the total number of houses on Algebra Avenue.
2b+3t-95=b+t =>
b+2t=95 .................(1)
The number of two-story houses is three times greater than the number of three-story houses.
b=3t .....................(2)
Substitute (2) in (1)
3t+2t = 95
5t=95
t=19 ......................(3)
substitute (3) in (2)
b=3t=3*19 = 57 .........(4)
Substitute (3) & (4) in (1)
b+2t=57+2*19=95 checks
Substitute (3) & (4) in (2)
b=3t=3*19=57 checks.
