Are 5(2x-y) and 15x-5y equivalent expressions?

krek1111 [17]

No, they are not equivalent.

5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.

After a weekend at the beach, Lisa has $274 less than she had when she left. The equation that represents this situation is e=s−

Anon25 [30]

Well that's easy it basically tells you all you gotta do is plug in the numbers

"E" is what you're trying to find out so you don't know that one it stays the same.

"S" is the amount of money she started with and it says she started with $500

And then she has $274 less than she started with.

E = 500 - 274

E= 226

She is left with $226 after her weekend at the beach.

~Hope it helped~

What is the value of y in this system of equations: 3x + y = 9 y = –4x + 10 ?

Ahat [919]

3x + y = 9 (I)
y = –4x + 10 (II)
------------------------
 $\left \{ {{3x + y = 9 } \atop {y = -4x + 10 }} \right.$

Pass the incognito "4x" to the first term, changing the signal when changing sides.
-------------------------
simplify by (-1)
 $\left \{ {{3x + y = 9.(-1)} \atop {4x + y = 10 }} \right.$ 

-------------------------
 $\left \{ {{- 3x - \diagup\!\!\!\!y =-9} \atop {4x + \diagup\!\!\!\!y = 10}} \right. 
$

-------------------------
 $\left \{ {{- 3x = - 9} \atop {4x = 10}} \right.$ 

-----------
 $\boxed{x = 1}$ 

Substitute in equation (I) to find the value of "Y".

3x + y = 9 (I)
3*(1) + y = 9
3 + y = 9
y = 9 - 3
$\boxed{y = 6}$

Answer:
$\boxed{\boxed{ \left \ {{x=1} \atop {y=6}} \right. }}$

paco has 75 minutes before he needs to get ready for baseball practic.he cleans his room for 40 minutes and reads and reads for

fomenos

By the way this problem is worded, he spends 75 minutes reading and cleaning, but there seems to be not enough information because the way it is worded, it means he has 75 minutes until he needs to GET READY, not play in the actual game. (40 + 35 = 75).
