Composite number is made up of 2 or more prime numbers
a prime number is only made up of itself and 1
composite and prime numbers are like oposites
a prime is not a composite but it is a prime number
confusing quesiton
first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
Answer:
The answer is -4
Step-by-step explanation:
-2x-6<=1
-2(-4)-6<=1
8-6<=1
2<=1 which is False
-2x-6<=1
-2(-3)-6<=1
6-6<=1
0<=1 which is True
-2x-6<=1
-2(-2)-6<=1
4-6<=1
-2<=1 which is True
-2x-6<=1
-2(-1)-6<=1
2-6<=1
-4<=1 which is True
Given that we Jenny wants to equivalent fraction of 45% then convert into reduced fraction and then convert into decimal equivalent.
She has already shown her work. We just need to find the error if any.
to convert any percent value we just divide that number by 100 because percent itself means divide by 100.
Hence first step 45%=45/100 is correct.
Then she needed to convert into reduced fraction. To do that she divided numerator and denominator both by 5 and got 9/20.
step 2 is also correct.
Now she needs to convert into decimal equivalent so she divided 9 by 20 and got 4.5 while the correct answer should be 0.45
Hence she did error when converting fraction form into decimal form.
