Answer:

-37

Step-by-step explanation:

2 x 3 + 57 -100

we do something called pemdas

We start with multiplying first

2 x 3 = 6

Then we do addition

6+57 = 63

then we subtract

63- 100 = -37

Answer:

-37

Step-by-step explanation:

assuming this equation is written correctly, you have to multiply first, think about PEMDAS

2x3=6

then you add. adding and subtracting, you do whichever is first in the math sequence.

6+57=63

63-100= -37

hope this helps :)

Sally needs 2/3 of a pound of potatoes. This is 1/3 of a pound more than 4/3 of the potatoes Sally has in her pantry

amid [387]

Lets assume, Sally has X pound of potatoes in her pantry.

So, 4/3 of the potatoes Sally has in her pantry = $\frac{4}{3}X$

Now, Sally needs 2/3 pound of potatoes and this 2/3 pound of potatoes is 1/3 pound more than that $\frac{4}{3}X$

So the representing equation will be:

$\frac{2}{3} = \frac{1}{3}+ \frac{4}{3}X$

$\frac{2}{3} - \frac{1}{3} = \frac{4}{3} X$ (subtracting $\frac{1}{3}$ from both sides)

$\frac{1}{3}= \frac{4}{3}X$

$1= 4X$ (multiplying both sides by 3)

$X =\frac{1}{4}$

So, Sally has $\frac{1}{4}$ pound of potatoes in her pantry.

You roll a 6 sided die. What is P(roll great her than 4)? If necessary round your answer to 2 decimal place

brilliants [131]

Answer:

1/3 = 0.33

Step-by-step explanation:

in a 6 sided die, there are numbers 1, 2, 3, 4, 5 and 6. So if you roll it once, there are 6 possible outcomes. so 6 is your sample space.

Out of all the possible outcomes, 5 and 6 are the only outcomes greater than 4.

P(an event occurring) = (number of ways it can occur)/(sample space)

∴p(roll greater than 4) = 2/6

=1/3

=0.333333333333333333333333............................

=0.33 (when rounded off to the 2nd decimal place)

So that's it!!! Hope i helped ya :)

Hey there ,. Anyone Know How to solve Differential equation??

allsm [11]

Here is a step-by-step method for solving them:

1. Substitute y = uv, and

dy/dx = u

dv/dx + v

du/dx

into

dy/dx + P(x)y = Q(x)

2. Factor the parts involving v

3. Put the v term equal to zero (this gives a differential equation in u and x which can be solved in the next step)

4. Solve using separation of variables to find u

5. Substitute u back into the equation we got at step 2

6. Solve that to find v

7. Finally, substitute u and v into y = uv to get our solution!

I'm so sorry if the explanation is confusing but I hope it's helps you to solve ^ ^
