Solve the following system of equations by substitution

den301095 [7]

Answer:

c. (2, -18)

Step-by-step explanation:

y = -5x - 8

y = 3x - 24

3x - 24 = -5x - 8

8x = 16

x = 2

y = 3x - 24

y = 3(2) - 24

y = 6 - 24

y = -18

The arithmetic mean (average) of four numbers is 85. If the largest of these numbers is 97, find the mean of the remaining three

Margaret [11]

Answer:

81

Step-by-step explanation:

Let's do this systematically:

Four numbers: a, b, c, d

Whose mean is 85: $\frac{a + b + c + d}{4} = 85$

Whose largest number is 97: $\frac{a + b + c + 97}{4} = 85$

Lets solve for the other numbers:

a+b+c+97 = 85*4 = 340

340 - 97 = 243

a+b+c = 243

at this point it doesn't matter what the numbers are, they just need to add up to 243.

We can do 243÷3=81, which is our answer
