Luis has 40 noah 45 nickels , 33 dimes, 10 quarters and 18 fifty-cent coins . how much money does he have
Aleksandr [31]

Answer:

$13.75 should be your answer

Step-by-step explanation:

Note that 45 nickles = 45 x 5 = 225 cents

Note that 10 quarters = 10 x 25 = 250 cents

Note that 18 half-dollars = 18 x 50 = 900 cents.

225 cents = $2.25

250 cents = $2.50

900 cents = $9

Add

2.25 + 2.50 + 9 = 13.75

x = 3y - 1

2y + x = x + 18


2y + 3y - 1 = 3y - 1 + 18

5y - 1 = 3y + 17

2y = 18

y = 9


x = 3(9) - 1

x = 27 - 1

x = 26

Given the function h(x) = 4x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
Ronch [10]

Answer with explanation:

The average rate of change in a function f(x) from x=a to x=b is given by :-

k=\dfrac{f(b)-f(a)}{b-a}

For Section A .

The average rate of change in a function h(x)=4x from x=0 to x=1 is given by :-

k=\dfrac{h(1)-h(0)}{1-0}\\\\=\dfrac{4-0}{1}=4

For section B .

The average rate of change in a function h(x)=4x from x=2 to x=3 is given by :-

k=\dfrac{h(3)-h(2)}{3-2}\\\\=\dfrac{12-8}{1}=4

The average rate of section A is same for section B because the function is a linear function, and the rate of change of a linear function is constant.
