Answer:

the price for each doughnut is $1.05

Step-by-step explanation:

doughnuts = d

cookies = c

2d + 3c = $3.30

5d + 2c = $4.95

to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.

4d + 6c = 3.30

-15d - 6c = -14.85

combine like terms

-11d = -11.55

divide by -11

d = 1.05

THEIR AGES
snow_tiger [21]

Answer:

Tom’s age is 7 years

Mary’s age is 13 years

Step-by-step explanation:

Since we do not know the ages, let’s represent the ages by variables at first.

Let m represent mary’s age will t represent Tom’s age.

Now, let’s proceed to have equations.

Adding square of Tom’s age (t^2) to mary’s age give 62

t^2 + m = 62 •••••••(i)

Adding square of mary’s age (m^2) to Tom’s age give 176

m^2 + t = 176 •••••••(ii)

Now, to get the individual ages, we will need to solve both equations simultaneously.

Solving both equations simultaneously without mathematical softwares can be a little hard.

By the use of mathematical software ( wolfram alpha to be specific), we can input both equations and allow the software to solve.

By inputing these equations, we have the values of t to be 7 and m to be 13

And if we try to check by inspection, we can see that these values are actually correct.

7^2 + 13 = 62

13^2 + 7 = 176

Answer:

woven blanket

Step-by-step explanation:

The artifact with the lowest elevation would be the artifact that was found in the <u>least</u> amount of feet, most likely being negative.

Thus, given the information above, we can conclude that the answer is woven blanket because it was found at -977 feet, and no other artifacts in the table were found any lower.
