What is the last digit of

Mathematics

Answer:

<em>Answer C. 5</em>

Step-by-step explanation:

<u>Product of Odd and Even Numbers</u>

Any number ending in 5 is necessarily a multiple of 5. For example, 85, 1005, 12345 are all multiple of 5.

Any number ending in 0 is a multiple of 5 and even therefore, is a multiple of 10.

Any integer number multiplied by another number ending in 5 gives one of these possible results:

* A multiple of 5 if the number is odd

* A multiple of 10 if the number is even.

The given product 1*3*5*7*9*11*13 is a multiple of 5 because 5 is one of the factors, and since the rest of the factors are all odd numbers, then the result is a multiple of 5 and has its last digit of 5.

Step-by-step explanation:

When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).

=> Last digit = 0 or 5.

Since 0 is not an option here, the answer must be 5. (C)

1/10x+9/10=1/10(BLANK)
Sonja [21]

Answer:

x=-8

Step-by-step explanation:

1 Simplify 1/10x to x/10.

x/10 + 9/10 = 1/10

2 Join the denominators.

x+9/10 = 1/10

3 Multiply both sides by 10.

x+9 = 1/10×10

4 Cancel 10.

x+9=1

5 Subtract 9 from both sides.

x=1-9

6 Simplify  1-9 to  -8.

x=-8

3 (2x-1 ) +7 = - 44 ( solve for x)
s344n2d4d5 [400]

Answer:

x = - 8

Step-by-step explanation:

To solve for x, isolate it by "moving" everything else over to the other side. This is done in reverse BEDMAS order using the reverse operations of number you want to move.

3 (2x-1 ) +7 = - 44   Simplify first using distributive property over the brackets

6x - 3 + 7 = - 44    Combine like terms, terms that have the same variables

6x + 4 = - 44

6x + 4 - 4 = - 44 - 4   Subtract 4 from both sides to cancel it out on the left side

6x = - 48

6x/6 = - 48/6   Divide by sides by 6 to cancel out the 6 from 6x

x = - 8    Final answer
