Answer:
x = 129
y = 82
Step-by-step explanation:
x + 51 = 180
x = 180 - 51
x = 129
y + 51 + 47 = 180
y = 98 - 180
y = 82
Answer:
1:2
Step-by-step explanation:
First, find how many are green
Add up the number of blue and red ones:
10 + 15 = 25
Subtract this from 50
50 - 25 = 25
So, 25 are green.
Since there are 50 marbles in total, the ratio will be 25:50
This can be simplified, since both numbers are divisible by 25.
So, the ratio is 1:2
Step-by-step explanation:
First sort the number in order to lowest to highest
4, 6, 6, 9, 11, 19, 23, 34
The number in the middle is the median
Since both 9 and 11 are in the middle you need to find the mean of 9 and 11
9+11=20
20÷2=10
The median is 10.
