Answer:
Mode is the most common
Median is the middle number when put in order of smallest to biggest
Mean is where you added them all up and divide by how many there is
Step-by-step explanation:
5, 7, 6, 7, 10
The median of these numbers is 7
The mode is 7
The mean is also 7 (5+6+7+7+10=35 35÷5=7)
X+y=2 (label equation one)
x-y=4 (label equation two)
y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2
x-(-x+2)=4
x+x-2=4
2x-2=4
2x=6
x=3
sub x=3 into equation one
3+y=2
y=-1
therefore x=3 and y=-1
Answer:
27 Marbles
Step-by-step explanation:
Alan first had 5 marbles, and then <em>added</em> 4 to the collection.
5 + 4 = 9
He went to the store and tripled the number of marbles he had.
9 x 3 = 27
Hence, he now has 27 marbles.
