6(3x-5)-7x=25
18x-30-7x=25
11x=55
x=11
-2(5+6m)+16=-90
-10-12m+16=-90
-12m+6=-90
-12m=-96
m=8
You can just use a calculator but when you add the numbers all together you get 323

Answer:
The least common multiple would be 105.
Step-by-step explanation:
You would do list out the multiples for each. Or multiply
Since 3 x 30 is 90, and 3 x 5 is 15, This is 105
And since 5 x 20 is 100, and 5 x 1 is 5, This is 105 as well
Also, since 7 x 10 is 70, and 7 x 5 is 35, This is 105.
The LCM is 105
Have a great Day!
Answer:
The correct option is;
a) It moves five places to the right
Step-by-step explanation:
Multiplying a whole number by 10 raised to a given (positive whole number) power, involves the shifting of the positioning of the decimal places to the right, depending on the value of the positive whole number power to which the 10 is raised
Similarly, multiplying a whole number by 10 raised to a given (negative whole number) power, involves the shifting of the positioning of the decimal places to the left, depending on the value of the negative whole number power to which the 10 is raised.
The reason is because, the number base generally used for arithmetic is in base 10 and multiplying or dividing by 10 is what is required to change a number's place value
Therefore, multiplying a whole number by 10 raised to the 5th power (10⁵) requires shifting the decimal place 5 places to the right
Example:
x.0 × 10⁵ = x00000.0
Where, x is a whole number.
