9x+1 = 2x+15
Subtract 1 from both sides.
9x=2x+14
Subtract 2x from both sides.
7x=+14
Divide 7 on both sides.
x=2
Answer:
2 pieces of 3/8 yard.
Step-by-step explanation:
They tell us that originally the fabric measures 3/4 of a yard and then it is cut and remains pieces of 3/8 of a yard, so we must know how many pieces could have been cut so that they will be this size, therefore we must divide:
3/4 / (3/8) = 2
Which means there are 2 pieces of 3/8 yard.
In statistics, the amount of degrees of freedom is
the quantity of values in the final computation of a statistic that are free to
differ. In this case, you can get the answer by adding the number of bags
and subtracting 1.
So in computation, this would look like: 3 + 2 + 1 + 2 - 1 =
7
Therefore, 7 is the degrees of freedom.
Answer:
17,19,21
Step-by-step explanation:
let the first odd number be "x"
formular : (x)+(x+2)+(x+4).
3x+6=57
3x=57-6
3x=51
x=51/3
x=17
apply the formular.
17,(17+2),(17+4)
17,19,21.
