Answer:
X= -3;
Y=78
Step-by-step explanation:
A: X+Y=75
B: 10X+Y=48
B-A: (10X+Y)-(X+Y)=48-75
10X+Y-X-Y= - 27
9X=-27
X= -3;
Now
A is : -3+Y=75
Y=75+3=78

Answer:
10 packages of hot dogs bought.
Step-by-step explanation:
It is 10. It says that you bought 12 packages of MEAT, not hot dogs alone. So...
$4 * 10
= $40
$10 * 2
= $20
$40 + $20
= $60

For #1: The sum of all 3 angles in a triangle will be 180. So since one corner is a right angle, that’s 90. The other angle is 17. So 90 + 17 = 107. Then do 180 -107 to find the last number. Which is 73!
Ebony makes 2000 dollars. She spends 450
so 2000 - 450 = 1550
1550/2000 = 0.775
or .78
100 - 0.78 = 0.22
22% is your answer
hope this helps
