Mai's penny bank can hold 498 pennies without being full.

1/2 is equal to 5/10.

When Mai removes 200 pennies from her penny bank, the container drops from 7/10 full to 5/10 full.

7/10-5/10=2/10=1/5

200 pennies is 1/5 the capacity of the penny bank.

1/5 of the bank is 200 pennies, so a full bank is 1000 pennies.

How do I figure out what 1/10 of 6000 is?
alisha [4.7K]
The way I like to figure out problems like this is to write it out like,

1/10 = x/6000
(One over ten equals x over 6000)

Then you find out how much you multiplied 10 by to get 6000. To do this you can divide 6000 by 10 getting 600. The rule "what you do to the bottom you have to do to top" in this equation. So since you multiplied the bottom by 600 you have to multiply the top by 600 as well. 600 times 1 is just 600.

So your answer is, 600 is 1/10 of 6000.

Hope this helps and isn't too confusing.

How many solutions does this system of equations have? Use either the substitution method or the elimination method. −2x + 4y =
Katen [24]
-2x+4y=4 Equation 1
x-2y=6 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=2y+6 
Substitute value of x in equation 1
-2(2y+6)+4y=4
-4y-12+4y=4
-12=4
-16=0
Which is false.

The measure of an angle is twenty-four times the measure of its complementary angle. What is the measure of each angle?
Bogdan [553]

Answer:

<h2>         3.6° and 86.4°</h2>

Step-by-step explanation:

24x   - measure of an angle

x      - the measure of a complementary angle

Complementary angles adds to 90°

x + 24x = 90°

25x = 90°

x = 90°÷25

x = 3.6°

24x = 24·3.6° = 86.4°
