Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 29
pennies, 16 dimes, and 17 quarters. The rest of the coins are nickels. There are 74 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could
you use to find n?

Answers

Answer:

62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So

29+16+17= 62

or if you want to impress then start with the total and subtract each given coin count

74-29-16-17=12

74-12=62

P=18
Angle e and c are the same because they are opposite interior angles. Therefore you can set it up in an equation like: 117=5P+27 and solve.
117=5P+27 you need to subtract 27 from both sides
90=5P you need to divide both sides by 5 to get
P=18

Answers

Answer:

a = -1

b = 6

Step-by-step explanation:

a = -b + 5

2b + a = 11

2b + a = 11

2b + (-b + 5) = 11

2b - b + 5 = 11

b + 5 = 11

b = 11 - 5

b = 6

2b + a = 11

2(6) + a = 11

12 + a = 11

a = 11 - 12

a = -1

Answer:

5 cookies left

Step-by-step explanation:

First you make the fraction equal by multiplying them

2/3 multiply both numerator and denominator by 4

= 8/12

Now you divide 60 by 12 to find the amount to make the denominator 60

60 divided by 12 = 5

8/12 multiply both numerator and denominator by 5

= 40/60

So now we know the amounts

She gave 40 away so she has 20 left (60 - 40 = 20)

Now make 3/4 numerator and denominator by equal to 20

Multiply them by 5

15/20

She had 5 cookies left

PLEASE HELP ME!!
let g be the function given by g (x) = 3x^4 - 8x^3. At what value of x on the closed interval [ -2,2 ] does g have an absolute maximum

Answers

Take the derivative:
g’(x) = 12x^3 - 24x^2

Set equal to zero and solve:
0 = 12x^3 - 24x^2
0 = 12x^2 (x - 2)

x = 0 or x = 2

Plug back into original
g(0) = 3(0^4) - 8(0^3)
g(0) = 0 - 0
g(0) = 0

g(2) = 3(2^2) - 8(2^3)
g(2) = 3(4) - 8(8)
g(2) = 12 - 64
g(2) = -52

There is an absolute max at (0,0) or when x = 0

The value of x on the closed interval [ -2,2 ] that g has an absolute maximum is 0

Given the function [tex]g (x) = 3x^4 - 8x^3[/tex]

The function is at a maximum at g'(x) = 0

Differentiating the function given:

[tex]g'(x)= 12x^3-24x^2\\0= 12x^3-24x^2\\ 12x^3-24x^2=0\\12x^2(x-2)=0\\12x^2=0 \ and \ x - 2 = 0\\x = 0 \ and\ 2 \[/tex]

Substitute x = 0 and x = 2 into the function;

g(0) = 3(0)^3 - 8(0)^3

g(0) = 0

Since the range of the function is least at x = 0, hence the value of x on the closed interval [ -2,2 ] that g has an absolute maximum is 0
