MArishka [77]3 years ago
4 0

Answer:

-2 1/3

Step-by-step explanation:

To find the opposite of a number, you just multiply it by -1 and that's the opposite. Let me know if that makes sense.

In other words, you just add a negative if it's a positive number and remove the negative if it's a negative number

The doble number line shows that jonah needs 28 seconds to fold 2 shirts. Based on the double number line, how long does jonah n
nikklg [1K]

We are given the double number line shows that Jonah needs 28 seconds to fold 2 shirts.

Let us find the number of seconds to fold 1 shirt.

In order to find the number of seconds to fold 1 shirt, we need to divide 28 by 2.

On dividing 28 by 2, we get

28/2 = 14 seconds.

We need to find the number of seconds to fold 5 shirt.

Each 2 shirts needs 28 seconds.

Therefore, 4 shirts would need = 28 + 28 = 56 seconds.

<em>And 5 shirts would need = 28 + 28 + 14 = 56 + 14 = 70 seconds.</em>

<h3>Therefore, Jonah needs 70 seconds to fold 5 shirts.</h3>

Write a recursive formula for the sequence –2, 4, –8, 16, ...<br><br> please help and thank you
vaieri [72.5K]

Answer:

see explanation

Step-by-step explanation:

A recursive formula allows us to calculate any term in the sequence from the previous term.

These are the terms of a geometric sequence with r being the common ratio between consecutive terms.

r = 4 ÷ - 2 = - 8 ÷ 4 = 16 ÷ - 8 = - 2

Multiplying a particular term by - 2 gives the next term in the sequence.

Hence recursive formula is

a_{n+1} = - 2 a_{n} with a₁ = - 2

Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is T
soldier1979 [14.2K]

Scientific Notation is the way of <u>writing a number or expressing them</u> in a <u>shorter or more compact way.</u>

No, <u>Taylor's resoning is incorrect</u> because  2,800,000 = 2.8  * 10^{6}

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  2.8  * 10^{6}.  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, <u>Taylor's reasoning is incorrect. </u>

Add altogether 5x+7, 3x-8 and 6x-25
Alisiya [41]

Answer:

14x - 26

Step-by-step explanation:

We have

5x+7 + 3x - 8 + 6x - 25

When adding these terms make sure to separate the variables from the numbers. We can do this by rearranging terms.

So, (5x + 3x + 6x) + (7-8-25)

Adding these gets us 14x - 26
