I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coin

Alenkinab [10]

Answer:

(35k + 20) cents

Step-by-step explanation:

First of all, let us have the value of each unit:

1 quarter = 25 cents

1 nickel = 5 cents

1 dime = 10 cents

Given that number of quarter = k

Quarters are 5 lesser than Nickels, so number of nickels = k+5

One more than twice as many dimes as quarters:

k = 2 $\times$ Number of Dimes + 1

So, number of dimes = $\frac{1}{2}(k-1)$

Value of quarters = $25 \times k$ cents

Value of nickels = $5 \times (k+5) = (5k+25)\ cents$

Value of dimes = $\frac{1}{2}(k-1) \times 10 = (5k-5)\ cents$

So, total value of coins =

$25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents$

y+2 = 3y-4 =

y+6 = 3y

6 =2y

y = 3

y+2 = 3+2 = 5

3y-4 = 3(3)-4 = 5

5+5 =10

2y-3 = 2(3) - 3 = 3

3+3 = 6

10+6 = 16 miles

answer is C

URGENT PLEASE HELP 45 POINTS! Complete this activity. Given: f(x) = x + 2 [f(x)] 2 =

ivanzaharov [21]

We are told that f(x) = x + 2. We want to find $(f(x))^{2}$ .

Squaring f(x) on one side means we square x + 2 on the other.

So,

f(x) = x + 2

(f(x))² = (x + 2)²

= (x + 2)(x + 2)

We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.

= x² + 2x + 2x + 4

= x² + 4x + 4

So [f(x)]² = x² + 4x + 4
