Answer:
4.4
Step-by-step explanation:
4 (4.4) ≥ 18 does not make sense. 4 x 4.4 = 17.6, which is not more than or equal to 18.
Answer:
x = -3, y = 2
Step-by-step explanation:
x - y = -5
x = -5 + y
Let's put this into the other equation
(-5 + y) + y = -1
-5 + 2y = -1
2y = 4
y = 2
Now we can solve for x by plugging y into either equation
x + (2) = -1
x = -3
Answer:
-18
Step-by-step explanation:
you add 12 and six together and you get 18. Then you put a negative sign in front of it
Margo must buy 60 tiles for the cost to be the same at both stores.
Step-by-step explanation:
Let x be the number of tiles purchased
Then
For Store 1:
24+0.79x
For store 2:
1.19x
For the number of tiles, we have to put both expression equal

subtracting 24 from both sides

Subtracting 1.19x from both sides

Dividing both sides by -0.4

Hence,
Margo must buy 60 tiles for the cost to be the same at both stores.
