Simora [160]

Answer:

2a - b = 5

Step-by-step explanation:

4a - 2b = 10

take out the highest common factor of the left side

2(2a - b) = 10

divide both sides by two

2a - b = 10/2

2a - b = 5

XLiV represents 64 true ya false

V125BC [204]

Answer:

False

Step-by-step explanation:

Given

$XLIV = 64$

Required

True or False

The above numeral can be split as follows:

$XLIV = XL + IV$

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

$XL = -10 + 50$

$XL = 40$

In Roman numerals;

$IV = 4$

Substitute 40 for XL and 4 for IV.

$XLIV = 40 + 4$

$XLIV = 44$

Hence;

$XLIV = 64$ is false

How many integers between 199 and 599 are multiple of 3

Reptile [31]

A.P. series would be: 201, 204, 207 .... 597
Here, a = 201, d = 3, l = 597

Now, l = a + (n - 1) d
597 = 201 + (n - 1)3
597 - 201 = 3n - 3
396 + 3 = 3n
n = 399/3
n = 133

In short, Your Answer would be 133

Hope this helps!

A certain arithmetic sequence has the following explicit formula for the nth term: an = 3 + (n - 1)(8) The same sequence has the

zhuklara [117]

From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
