Answer:

x = -1, y = 1

Step-by-step explanation:

2x-y=-3 // y = 2x + 3 (eqn 1)

3x+y=-2  (eqn 2)

sub 1 into 2

3x + 2x + 3 = -2

5x = -5

x = -1

sub x = -1 into eqn 1

y = -2+3

y = 1

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain
GarryVolchara [31]
Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10


423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!

You went to the mall with $80. You spend 25% of the money on shorts and 65% of the remainder on sandals. How much did the sandal
sukhopar [10]

25% of 80

25/100 or 1/4 x 80 = 20

So $20 were spent on shorts, then $60 were left over.

65% of 60 on sandals.

so 65/100 x 60 = 39

So we can see that the sandals cost $39.
