Step-by-step explanation:
1) -5x<35
we divide both sides by 5
-5x/5<35/5
-x<7
we divide both sides by-1 to remove the negative sign
-x/-1<7/-1
x<7/-1
2) 2x>-42
we divide both sides by 2
2x/2>-42/2
x>-21
3) x/3≤-7
we multiply by 3 and we cancel 3
3(x/3)≤3(-7) we cancel the 3
x≤-21
4) x/-4≥-4
we do the same thing
x≥1
The square root of 36 is 6 and the square root of 25 is 5. 30 is in between 36 and 25 so the square root should be between 6 and 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.
