The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.
Examples:
3.1 x 10 = 31
3.1 x 10 x 10 = 31 x 10 = 310
Each time you multiply by another 10, the decimal point moves one more place.
In your exercise, says you're going to multiply by 10 <u>three</u> times in a row. So that will move the decimal point 3 places to the right.
So what do you get if you move the decimal in 4.25 three places to the right?
Answer:
Part 1: The transitive property of equality states that where given that item one is equal to item two, where item two is then equal to item three, then item one is also equal three.
Mathematically, the transitive property can be written as follows;
When X = Y, and Y = Z, then also X = Z
Part 2: The transitive property of equality can be represented using angles as follows
Given ∠A and ∠B are the base angles of an isosceles triangle, then ∠A ≅∠B also ∠B and ∠C are vertically opposite angles, then ∠B ≅ ∠C, therefore, ∠A ≅ ∠C.

Answer: 5 nickels and 19 quarters
Step-by-step explanation:
Let represent the number of nickels and let represent the number of quarters.
From the problem we can write these two equations:
+ = 24; (0.05) + (0.25) = 5.00
Isolate in the first equation: = 24 − .
Substitute 24 − for and solve for :
(24 − )(0.05) + (0.25) = 5.00
24(0.05) − (0.05) + (0.25) = 5.00
1.20 − 0.05 + 0.25 = 5.00
1.20 + 0.20 = 5.00
0.20 = 3.80
= 19
Use = 19 to find :
+ = 24; + 19 = 24; = 5
Answer: 5 nickels, 19 quarters
Hope this helps!
