6. 63(Could have counted wrong. Mode is the number that appears the most in a set of data)
7. Couldn't solve sorry!
Answer:
Step-by-step explanation:
Remark
Let x by the multiplying factor to make up 190 m.
2x + 5x + 3x = 190
10x = 190
x = 190/10
x = 19
The longest side is 5x
The longest side = 5 * 19 = 95
So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2
the number is 2
