Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ <u>35x - 15y = -160</u>
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6
I got the answer to be 42.
To answer this item, let us convert first one of the given dimension such that both numbers will take only the same units for easier comparison. It should be noted that every liter (L) is consists of 1000 mL.
Aria: (500 mL)(1 L/1000 mL) = 0.5 L
Andrea: 0.75 L
Since, 0.75 L is higher compared to 0.5L, the answer to the item is Andrea.
The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
