4 x = 36
Step-by-step explanation:
Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.
Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.
Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..
4x = 36
Answer:
(x+3)(x+5)
Step-by-step explanation:
what two numbers will multiply to 15 and add up to 8?
3 and 5
so
(x+3)(x+5)
Answer:
30% probability that it is either red or yellow
Step-by-step explanation:
We have that:
10% of the candies are green
10% of the candies are red
20% of the candies are yellow
20% of the candies are blue
20% of the candies are orange.
The rest is brown. The percentage of brown candies is not important to this problem.
If you pick a candy at random, what is the probability that it is either red or yellow?
10% are red
20% are yellow
10 + 20 = 30%
30% probability that it is either red or yellow
Answer:
Perimeter: 44
Area: 96
Step-by-step explanation:
Perimeter - Just add all the sides together, 4 + 10 + 12 +7 + 8 + 3.
(The 8 and the 3 are apart of the sides that are not labeled. Since 12 - 4 = 8, and 10 - 7 = 3, That's where these numbers come from.)
Area - 4 * 10 = 40,
+ 8 * 7 = 56,
--------------------------------
= 96
I hope this helps :)
