We will use B for the number of baseball cards and H for the number of hockey cards.
B = 5H
B + H = 840
Use substitution by plugging 5H in for B in the second equation.
5H + H = 840
6H = 840
H = 140
If there are 140 hockey cards, then there are 5*140 = 700 baseball cards.
So the answer is 700.
Step-by-step explanation:
1) 339.1
2) 615.4
3) 401.9
4) 2210.6
5) 2769.5
all you need to do is see if the numbers (after decimal) right after is bigger or smaller that 5. If it is greater that 5, then you add 1 to the number before it. (Ex: round 17.26 to nearest tenth, 17.3) if it is smaller then 5, it stays the same, you just take off the other number. (Ex: round 17.21 to nearest tenth, 17.2) harder to explain than I thought it would
Remember you can do anything to an equaiton as long asyou do it to both sides
4v+18≥6v+10
minus 4v both sides
4v-4v+18≥6v-4v+10
0+18≥2v+10
18≥2v+10
minus 10 both sides
18-10≥2v+10-10
8≥2v+0
8≥2v
divide both sides by 2
8/2=(2v)/2
4≥(2/2)v
4≥1v
4≥v
v≤4
A mixed number has a part that is whole and a part that is a friction.
For example:
3 1/2 and 3 2/3
3 1/2 * 3 1/4 = 7/2 * 13/4 = 91/8 = 11 3/8
9 < 11 3/8 < 12
Answer:
14,740
Step-by-step explanation:
The mean of a set of data is another way of saying the average
To find the average you find the sum of all the numbers/amount of numbers
In this case it would be 221,100/15
