Answer:
the answer is
-x-8y=8
or, x + 8y= -8
Step-by-step explanation:
4x - 6y = 13 - (5x + 2y = 5)
or, 4x - 6y = 13
- 5x - 2y = -5
-------------------------
- x - 8y = 8
Start with the given equation:
Substitute known values:
Evaluate:
Similarly:
Answer: 5y
Step-by-step explanation:
Product means the multiplication of, so taking the product of 5 and y we simply have;
5*y=5y
It should be the multiplication first remember PEMDAS. Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction. So Letter D is the answer.
Answer:
Total temperature change = -32.48 degrees
Step-by-step explanation:
Over 11.2 hours, the temperature changed -2.9 degrees each hour.
Total time elapsed = 11.2 hour.
Temperature change per hour = -2.9 degrees
Total temperature change = Total time elapsed x Temperature change per hour
Total temperature change = 11.2 x -2.9 = -32.48 degrees
So temperature is reduced by 32.48 degrees in 11.2 hours.
Total temperature change = -32.48 degrees
