Does order of numbers matter for fractions

1 answer:

5 0

Answer: You can see it does matter in what order you solve the equation. ... Just like when you are solving equations with whole numbers, solving equations with fractions has the same order of operations. The order of operations is the order in which you solve the problem. If numbers are in parentheses, you do them first.

What is 10xy - 15y in factored form

Oduvanchick [21]

The factored form of 10xy - 15y is 5y(2x - 3)

Solution:

Given that, we have to write the given expression in factored form

Given expression is:

10xy - 15y

To find the factored form, let us first find the greatest common factor of 10 and 15

The factors of 10 are: 1, 2, 5, 10

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 5

Thus, factor out 5 from given expression

$10xy - 15y = 5(2xy - 3y)$

Now factor out the common term "y"

$10xy - 15y = 5(2xy - 3y) = 5y(2x-3)\\\\10xy - 15y = 5y(2x-3)$

Thus the factored form is found

Help,scatter plots please and thank you

Lady_Fox [76]

Answer: D

Step-by-step explanation:

Since a tadpole becomes a frog as it ages, it makes sense that the axis of the tail would go down as it ages since frogs don’t have tails. If you see the x axis as the tempature, and the coats as the y axis. It would make sense that as the tempature gets colder, more people would be buying coats. But basically, D is the only one that doesn’t have a cause and affect, so it wouldn’t have a very linear scatter plot. For example, I have the same letters in my name as someone I know who is 6‘ 4”, and I’m only 4’ 8”. So D wouldn’t make such a nicely formed scatter plot.

zubka84 [21]

Answer:

3/8 and 3/5

Step-by-step explanation:

Given that a family has three children. Using b to stand for a boy and g for girl give the following we can write sample space for a family having three children as

(bbb, bbg, bgg, bgb, gbb, gbg, ggb, ggg)

E - exactly two boys

Sample space count = 8

Exactly two boys count = 3

a) p(E) = $\frac{3}{8}$

b) odds for E is probability/1-probability

= $\frac{3}{5}$
