Step-by-step explanation:
1/4*5= 5/4
1 1/4
or do the same with decimals
(1/4=0.25)*5=
0.25*5=1.25
1.25=5/4=1 1/4

Answer:
P = 2(x + 5) + 2(2x - 3)
Step-by-step explanation:
GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate?
The shape of the gate is rectangular.
Hence, the Perimeter of a rectangle (the gate) = 2L + 2W
Where :
L = GR = x + 5
W = GP = 2x - 3
Hence,the perimeter of the gate is
P = 2(x + 5) + 2(2x - 3)
Answer:
what is the question
Step-by-step explanation:
A half-life of the isotope is 15 days and at start its mass is 32 g.
A table:
t: m:
0 32 g
15 16 g
30 8 g
45 4 g
60 2 g
75 1 g
In the first column is used an arithmetic sequence ( a 1 = 0, d = 15 ).
In the second column is used a geometric sequence ( a 1 = 32, r = 1/2 )
