If you want to evaluate it, -4q-(-8q)+10 is changed to -4q+8q+10 (two negatives equal positive). Next, -4q+8q is 4q (since the bigger number is positive 8q, you subtract and get 4q). Finally, your answer is 4q+10. Hope this helps! :)
Answer:
(-4, 5)
Step-by-step explanation:
The problem is a system of equations where you have two variables and can use the method of eliminate (eliminating one of the variables) to solve. In this case, you will need to multiply one of the fractions by a factor to eliminate a variable. It seems easiest to multiply the first equation by a factor of -5:
-5(x - 3y) = -24 (distribute) -5x + 15y = 120
Add the equations:
-5x + 15y = 120
<u>+5x + 8y = -5</u>
23y = 115 (divide by 23)
y = 5
Solve for 'x': x - 3(5) = -24 or x - 15 = 24 (add 15) x = -4
Ordered pair: (-4, 5)
"How much more than" hints that you need to subtract the original weight (10 oz.) from the current weight (15 pounds, 3 oz.).
Important: 16 oz. = 1 lb.
I'd suggest that you convert 15 lb, 3 oz. to oz, so that you can easily compare the cat's mature weight to its weight at 2 weeks.
15 lb 3 oz
- 10 oz (subtract 10 oz)
--------------------
? This is "how much more he weighs now."
Example: convert 2 lb 11 oz to oz.
Solution: (2 lb) (16 oz) / (1 lb) + 11 oz. Note how "lb" will disappear.
