Step-by-step explanation:
3)
25% of 15.99=0.25×15.99=3.9975
Nope you will save about 4 dollars.
4)
12$ is 100% of its price
If there is a 25% discount, it will cost 75% of its original value.
75% of 12=0.75×12=9
It will cost 9 dollars
5)
You have 40% left of 150
so, 0.4(150)=60
You ANSWERED 90 but you still have <u>6</u><u>0</u> remaining.
6)
60% of 1350 lived since 40% died
0.6×1350=810
about 810 lived
7)
40% of the angelfish died
0.4×230=92
92 angelfish died
8)
The collected 125% of what they expected
1.25×1200=1500
They collected 1500 cans

Answer:
D
Step-by-step explanation:
Since we already know what -y is we can use that to find y.
y = -5x -21.
Let's substitute that in the bottom equation
-4x -5x - 21 = 6.
Simplify.
-9x = 27.
x = -3
Let's solve using
y = -5x -21.
to find y.
y = -5(-3) - 21
y = 15 - 21
y = -6.
There you have it!
x = -3, y = -6
So.. The correct answer choice is D
