Answer:
The simplified form of r^-7 + s^-12 is ----> 1/r^7 + 1/s^12
Step-by-step explanation:
<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.
Answer:
(3,2)
Step-by-step explanation:
Y=-2x+8 equation 1
y=x-1 equation 2
x-1=-2x+8 substi y of second equation into y of first equation.
3x=9
x=3
solve for y by putting the x value into either equation
y=x-1
y=3-1
y=2
A
Step-by-step explanation:
- To compare decimal numbers with the same whole digits, we have to check the numbers in the decimal points.
- We compare the numbers in the same decimal point in both numbers e.g the tenth, hundredth or thousandth decimal numbers.
- Whichever number has a bigger value for the lowest decimal point is the larger of the two.
- Whenever the lowest decimal point is the same between the two, go to the next decimal point and compare.
2.01 is less than 2.2 because the tenth decimal in the previous number (that of 0) is less than the tenth of the latter number (that is 2).
