Hi there!
To solve this problem, we should simplify.
0.06x - 0.18 = 0.12
First, we should add 0.18 to both sides:
0.06x = 0.12 + 0.18
0.06x = 0.3
Now, we can convert 0.06 into a fraction and multiply both sides of the equation by its receprical to isolate x:
0.06 = 6/100
6/100 × 100/6 = 1
0.3 × 100/6 = 30/6
x = 30/6
x = 15/3
x = 5
So, x is 5.
Hope this helps!
X 0 1 2 3 4 5 6
y -6 -5 -4 -3 -2 -1 0
To estimate, you would usually round to a significant figure
so, 20* 70=1400
The actual answer is 1521, so we know we are close
They are usually represented like this
commutative property of addition
a+b=b+a
associative property of additon
(a+b)+c=a+(b+c)
identity property of addition
a+0=a
so number sentatnces
lets say a=1,b=2,c=3
commutative property of addition
1+2=2+1
associative property of addition
(1+2)+3=1+(2+3)
identity property of addition
1+0=1
