Answer:
30% decrease
Step-by-step explanation:
We have to divide 39 by 130 and then find the percentage of it. 39/130 is equal to 3/10, and 3/10 is equal to 30%. That means that it was a 30% decrease.
Answer:
Hi there, I believe the answer to this equation is: 2.8
Step-by-step explanation:
Subtract 7 on both sides so
5n+7=21-7
you are left with 5n=14 you need to get n by itself so divide 5 on both sides.
5n/5 = 14/5
n=2.8
Hope this is correct :)
Have a great day
5 + 3p <span>≥ 30 because you start with the 5 points from the first round then add 3 equal amount of points that have to end up being greater than or equal to 30</span>
A = dog food, b = cat food
1a + 2b= 25
2a + 1b = 26
simultaneous equations!!
2a + 4b=50
2a + 1b = 26
subtract from each other
2a - 2a = 0
4b - 1b = 3b
50 - 26 = 24
3b = 24
b = $8
then sub into equation
1a + 2(8) = 25
25-16 = 9
a= $9
