Answer:
x=1.428
Step-by-step explanation:
2×2+6=7x
According to the BODMAS rule the multiplication should be done first. thus,
(2×2)+6=7x
=4+6=7x
then add 4 and 6
4+6=7x
10=7x
then divide 10 by 7 inorder to find X
10=7x
x=10/7
=1.428
Answer:
Step-by-step explanation:
length of an arc(s) = θ/360 x 2πr

Answer:
x = 2
Step-by-step explanation:
8(7x-2)=96
7x-2 = 96 : 8
7x-2 = 12
7x = 12 +2
7x = 14
x = 14 : 7
x = 2
Half-life = [elapsed time * log (2)] / [log (begng amt / endg amt)]
half-life = (3 days * 0.30102999566) / log (1 / .58)
