Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g
Answer:
800 x 1.033^4 = 910.94 (result is rounded)
Step-by-step explanation:
Assuming you get paid every week.
Total num of weeks in a year = 52
Therefore weekly salary = 42,700/52 = 821.15
Salary of first 6 weeks = 821.15 * 6 = 4926.92
20% of first 6 weeks salary = 0.2 * 4926.92 =985.38
You must pay the ACME $985.38
