The answer is D. (2.9,-22.8)
Answer is D. Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for th remaining varables
We need to have common denominators, so I will multiply 1 1/2 by 4
15/8 + 12/8 + 7/8 = 34/8
4&1/4 pounds of meat
2x+y-3=0,x-2y=1 okay that's the answer good luck
We can first get the percentage of the emergency room visits that involves an injury.
6 out of 10.
This will be (6/10)×100 = 60%
So, if there are 930 emergency room visits, the expected visits <span>included a prescription for medication is;
</span>
60% of 930 = 60/100 × 930
= 0.6 ×930
= 558
