The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches
The streetlight is 12 ft 5 1/3 inches tall.

5. You can multiply 10 over 3 by the reciprocal of 2 over 3 to divide fractions. You get 30 over 6, and that simplifies to 5.
Answer:
x= 10, x=1
Step-by-step explanation:
(x-1)(x-10)=0
then solve for x
Answer:
b. 11
Step-by-step explanation:
You'll have two equations in this system. Let G represent George's marbles and M represent Miguel's marbles.
1. G+3=2M (George's marbles plus 3 equals twice of Miguel's)
2. G-4=M (George's marbles minus 4 equals Miguel's marbles)
We have an explicit M value, so we can use the substitution method. Substitute the second equation into the first for M: G+3=2(G-4).
After some algebra, you'll get G=11. George has 11 marbles.
