Step-by-step explanation:
twice the difference of a number and 6
2×(n - 6)
the correct options are
1.
3.
4.
5.
in other words : 2. and 6. are wrong, as there is no addition, and the expression has to be written with brackets to allow the subtraction to be done before the multiplication.
So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18
Y2-y1/x2-x1
4-6/10-1
-2/9 is the slope
y-y1=m(x-x1)
y-6=-2/9(x-1)
y-6=-2/9x-2/9
Multiply both sides by 9
9y-54=-2x-2
2x+9y=52
Therefore 2x+9y=52 is the equation
0.08 is 1/10 of 0.8. to do this, you need to multiply 0.08 by 10. the answer is 0.8 ( 8 tenths) the answer in fraction form is 8/10 which can be simplified to 4/5
