I mean I think so I’m not completely sure it’s a really hard question
Answer:
(-4+y)=-7
-4+y=-7
by adding 4 on both sides, we get

y=-3
Answer:
Lara has a total of 5(x + y) pansies
Step-by-step explanation:
Here, we want to write an expression for the total number of pansies owned by Lara.
From the question, she has x groups of violet pansies; So the total number of violet pansies will be x * 5 = 5x pansies
She has y groups of blue pansies so the total number of blue pansies = y * 5 = 5y pansies
So the total number of Pansies owned by lara is 5x + 5y = 5(x + y) pansies
In a full 52-card deck, there are 4 kings and 4 3's, which do not overlap.
Therefore the total number of "successes" is 4+4=8 out of a 52-card deck.
=>
The probability of drawing a 3 or a king out of a 52-card deck is 8/52=2/13.
