Answer:

The equation would be y = x + 5, in which x is the number of weeks and y is the number of books he has.

Step-by-step explanation:

We know this because even at 0 weeks, he still has 5 books. Therefore we put this as the constant at the end. Then we can add the number of weeks since the rate is one book per week.

Answer:

Price of a senior citizen ticket is $4 and price of a student ticket is $15 .

Step-by-step explanation:

Let us assume that the price a senior citizen ticket be x .

Let us assume that the price a student citizen ticket be y .

As given

The school that Jack goes to is selling tickets to a choral performance.

On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.

Equtaions becomes

9x + 8y = 156

As given

The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.

Equations becomes

7x + 9y = 163

Multipy 9x + 8y = 156 by 9 .

81x + 72y = 1404

Multiply 7x + 9y = 163 by 8 .

56x + 72y = 1304

Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .

81x - 56x + 72y - 72y = 1404 - 1304

25x = 100

$x = \frac{100}{25}$

x = $ 4

Putting value of x in the 56x + 72y = 1304 .

56 × 4 + 72y = 1304

224 + 72y = 1304

72y = 1304 - 224

72y = 1080

$y = \frac{1080}{72}$

y = $15

Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .

help finding the perimter of 78.4 inches whats the length of each side and show me how to work the promblem

LuckyWell [14K]

A square has four even sides and the perimeter is equal to the sum of all of the sides.
$P=s+s+s+s=4s$
So we can evaluate the equation for P and then solve for s.
$78.4=4s \\ \frac{78.4}{4} =s \\ s=19.6in$

In the diagram ABC is equal to DEC what is the value of x?

Hatshy [7]

$\begin{gathered} \frac{25}{5}=\frac{18-x}{x} \\ 25x=(18-x)\times5 \\ 25x=90-5x \\ 25x+5x=90-5x+5x \\ 30x=90 \\ \frac{30x}{30}=\frac{90}{30} \\ x=3 \end{gathered}$

Plz help me with this

Mkey [24]

Answer: B) A = 750(1.04)ⁿ

Step-by-step explanation:

The formula for compounded annually is: A = P(1 + r)ⁿ where

A (amount accrued) = unknown
P (amount invested) = $750
r (interest rate) = 4% -->(0.04)
t (time in years) = unknown

A = 750(1 + 0.04)ⁿ

= 750(1.04)ⁿ
