Yes
remember you can do anything to an equaiton as long as you do it to boh sides
ad try to get unknown to one side
9n-10=4n+10
minus 4n both sides
9n-4n-10=4n-4n+10
5n-10=0+10
add 10
5n+10-10=0+10+10
5n+0=20
5n=20
divide both sies by 5
5n/5=20/5
5/5n=4
1n=4
n=4
The truck is 171.2%. if you calculate the percentage of 160 and add them together, you will get 171.2
Answer:
x^9^y^2 z^4
Step-by-step explanation:
Number of flowers in the garden of Christina = 50
The ration of roses to daisies in Christina's garden = 1:4
Let us assume the common ratio to be = x
Then
x + 4x = 50
5x = 50
x = 50/5
= 10
Then
Number of roses in the garden of Christina = 1 * 10
= 10
Number of daisies in the garden of Christina = 4 * 10
= 40
So the number of roses in the garden of Christina is 10 and the number of daisies is 40.
