Answer:
To multiply a number by 0.01 move the decimal point <u>2</u> places to the <u>left</u>.
Step-by-step explanation:
for example, lets multiply 5 by 0.01
5 x 0.01=0.05
originally, 5 in decimal form is 5.0
when it is multiplied by 0.01, the decimal point moves first from 5.0 to 0.5, then 0.5 to 0.05
Hey there, if 1 kilogram equals 1,000 grams, then 2 kilograms equals 2,000 grams. Now, we divide 1,000 by 2 and that would give us 500. Then, we add 2,000 by 500 and that would give us 2,500 grams. 2.5 kilograms equal 2,500 grams.
Im hungry where is it located?
For this case, the first thing we must do is define variables.
We have then:
x: number of $ 10 coins
y: number of $ 20 coins
We now write the system of equations that models the problem:
The graphical solution (see attached image) is given by the intersection of the equations.
We have then:
Answer:
Dave has:
26 $ 10 coins
24 $ 20 coins
