y + 35 = ( y ) + ( y - 31 )
y + 35 = 2y - 31
Add both sides 31
y + 35 + 31 = 2y - 31 + 31
y + 66 = 2y
Subtract both sides y
y - y + 66 = 2y - y
y = 66
3:5:7
3+5+7=15
15 units
33ft 9in =15 units
convert to feet
33ft=12in times 33=396in
396+9=405
405in=15units
divide both sides by 15
27=1unit
p=3units
p=3*27
p=81 inches=6ft 9in
q=5 units
q=5*27
q=135 inches=11ft 3in
r=7units
r=7*27
r=189 inches=15ft 9in
p=6ft 9in
q=11ft 3in
r=15ft 9in
The answer is D) 0.0000000692
<em>Explanation:
</em>Since the equation is
6.92 * 10^ -8
You know that you need to move the decimal 8 places to the left ( left is negative, right is positive)
If you move the decimal 8 places to the left the decimal still needs to pass the 6, so there will actually be 7 zeroes instead of 8.
