Answer:
x = 5
Step-by-step explanation:
20(20-x)=300
1. Divide both sides by 20.
20(20-x)/20 = 300/20
2. Simplify.
20-x=15
3. Subtract 20 from both sides.
20-x-29=15-20
4. Simplify.
-x=-5
5. Divide both sides by -1.
-x/-1 = -5/-1
6. Simplify.
x=5
<h3>
The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient. </h3>
Step-by-step explanation:
Let
Number of salmon steak = x
Number of baked eggs =y
and Number of acorn squash =z
Total amount of protein that is provided to the patient =40 x +20 y+3 z
Total amount of carbohydrates that is provided to the patient = 20 x+2y +15z
Total amount of vitamin A that is provided to the patient = x+25 y+ 37z
According to the problem,
40x+20y+3z=126, 20x+2y+15z=82 and x+25y+37z= 101.5
Solving the above equations
we get x= 2.5 ,y= 1 and z=2
So , The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient.
