Answer:
Yes, they can both be solved and get the same answer.
Step-by-step explanation:
<u>Tyler's way:</u>
Since Tyler solved first by isolating x, resulting in x=-5-3y, he can then go and look at the second equation and solve for y there. In the second equation you're going to want to subtract 9x from the right side and left side to then get 3y=3-9x. Now you're going to divide by 3 on both sides to isolate y. You'll get y=1-3x. Now we know what y equals. Plug that back into the first equation and you'll get x=-5-3(1-3x). Use the distributive property to simplify that and you'll get x=-5-3+9x. That simplified is x=-8+9x. Add 8 on both sides and you'll get 8+x=9x. Subtract x from the both sides and you'll get 8=8x. Divide by 8 on both sides and you'll get the final answer: 1=x, or x=1.
<u>Han's way:</u>
Since Han solved first by isolating 3y, resulting in 3y=-5-x, he can then go and look at the second equation and solve for y there. In the second equation you're going to want to subtract 9x from the right side and left side to then get 3y=3-9x. Now you're going to divide by 3 on both sides to isolate y. You'll get y=1-3x. Now we know what y equals. Plug that back into the first equation and you'll get 3(1-3x)=-5-x. Use the distributive property to simplify that and you'll get 3-9x=-5-x. Add 9x to both sides and you'll get 3=-5+8x. Add 5 to both sides to isolate 8x and you'll get 8=8x. Divide by 8 on both sides and you'll get the final answer: 1=x, or x=1.
Add total number of feet together.
=5 3/8+ 7 1/2+ 8 2/5
=5.375 + 7.5 + 8.4
=21.275 total feet of pipe (rounded to the tenths would be 21.3 feet)
Hope this helps! :)
Answer:
he would have had read 9/12 of the book in total
Step-by-step explanation:
Answer:
$
per minute.
Step-by-step explanation:
We have been given that a certain animated movie earned $
in revenues at the box office. The movie lasts 
minutes.
To find the revenue earned per minute of the movie we will will divide by .
Using quotient rule of exponents we will get,
We can write 0.1208791208791209 as 
.
Using product rule of exponents we will get,
Upon rounding our answer to two decimal places we will get,
Therefore, the movie had earned a revenue of $ per minute.
