Find the first 5 terms and explicit formula a1=35, d=4

1 answer:

3 0

The first five terms are: 35, 39, 43, 47, 51

We start with 35 and add on 4 each time to get the next term
35 = first term
35+4 = 39 = second term
39+4 = 43 = third term
43+4 = 47 = fourth term
47+4 = 51 = fifth term
and so on...

Chase and sara went to the candy store. Chase bought 5 pieces of fudge and 3 pieces of gum for 5.70. Sara bought 2 pieces of fud

tamaranim1 [39]

Let, price of fudge and gum is x and y respectively.

Converting given statements into mathematical equation.

We get :

5x + 3y = 5.70 ....1)

2x + 10y = 3.60 ....2)

Solving equation 1 and 2, we get :

x = $1.05 .

y = $0.15 .

Price of buying 20 pieces of fudge and 20 pieces of bubble gum is :

P = 20( 1.05 ) + 20( 0.15 )

P = $24

Hence, this is the required solution.

A scientist uses the equation shown below to predict the future population of a species. In the equation, y represents the estim

ololo11 [35]

Answer:

1200

Explanation:

y represents the estimated population

t represents the number of years.

The equation that predicts the population after t years is given as:

$y=150\times4^t$

Substitute t = 3/2 into the equation

$\begin{gathered} y=150\times4^{\frac{3}{2}} \\ y=150\times2^{2(\frac{3}{2})} \\ y=150\times2^3 \\ y=150\times8 \\ y=1200 \end{gathered}$

The closest valuie to the value of y is 1200

Answer:

9x + 5y = 29 ........... (1) and

3x + y = 7 ........... (2)

Each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens.

Step-by-step explanation:

Let, each game of ping pong requires x number of tokens and each game of pinball requires y number of tokens.

So, from the given conditions we can write

9x + 5y = 29 ........... (1) and

3x + y = 7 ........... (2)

Now, solving equations (1) and (2) we get,

9x + 5(7 - 3x) = 29

⇒ 35 - 6x = 29

⇒ 6x = 6

⇒ x = 1 token.

Now, putting x = 1 in equation (2) we get,

3 + y = 7

⇒ y = 4 tokens.

So, each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens. (Answer)
