Answer:
5x = 5(10) = 50 inches
Step-by-step explanation:
Let x = length of shorter piece then
5x = length of the longer piece
.
x + 5x = 60
6x = 60
x = 10 inches (shorter piece)
.
Longer piece:
5x = 5(10) = 50 inches
Answer:
3) 124
Step-by-step explanation:
a1 = 10
a2 = a1+6 = 10+6 = 16
a3 = a2+6 = a1+6+6 = a1 + 2×6 = 22
a4 = a3+6 = a2+6+6 = a1+6+6+6 = a1 + 3×6 = 28
...
=>
an = an-1 + 6 = a1 + 6(n-1)
=>
a20 = a1 + 6(20-1) = 10 + 6×19 = 10+114 = 124
Answer:
x=-5
Step-by-step explanation:
add 3 to -8
The dimensions of the rectangle is 2.45 m by 5/8 m
thus the area will be:
A=length*width
A=2.45×5/8
A=1.53125 m²
Perimeter will be:
P=2(L+W)
P=2(2.45+5/8)
P=2(3.075)
P=6.15 m
