Step-by-step explanation:

first, add 3 and 5 together to get the sandwiches robert already made. so you should get 8.

Now, subtract 12 and 8 to get the ham sandwiches (the rest). you should get 4.

So, 4 ( the ham ) should be fractured by 12 ( all kinds of sandwiches robert already made. now your final answer should be :

4/12

How do you write it:

3 + 5

= 8

= 12 - 8

= 4

= 4/12 #

now, 4/12 is already correct. however, you may have to simplify the equation. so now, your final answer should be:

1/3

(my english is not so good so i hope you can understand my explanation well enough.)

A swimming pool is filled with water by using two taps A and B. Alone, it takes tap A 3 hours less than B to fill the same pool.
iris [78.8K]

Answer:

Tap A 3hrs

Tap B 6hrs

Step-by-step explanation:

Let the volume of the swimming pool be Xm^3.

Now, to get the appropriate volume, we know we need to multiply the rate by the time. Let the rate of the taps be R1 and R2 respectively, while the time taken to fill the swimming pool be Ta and Tb respectively.

x/Ta= Ra

x/Tb= Rb

X/(Ra + Rb)= 2

Ta = Tb - 3

From equation 2:

X = 2( Ra + Rb)

Substituting the values of Ra and Rb Using the first set of equations

X = 2( x/Ta + x/Tb)

But Ta = Tb - 3

1/2 = 1/(Tb - 3)+ 1/Tb

0.5 = (Tb + Tb-3)/Tb(Tb - 3)

At this juncture let’s say Tb = y

0.5 = (2y - 3)/y(y - 3)

y(y-3 ) = 4y - 6

y^2 -3y - 4y + 6 = 0

y^2 -7y + 6= 0

Solving the quadratic equation, we get y =

y = Tb = 6hrs or 1hr

We remove one hour as we know that Tap A takes 3hrs left than tap B and there is nothing like negative hours

Now, we get Ta by Tb -3 = 6 - 3 = 3hrs

4/3C, when C=6<br> show your work here
tresset_1 [31]

4 divided by 3C

If C equals 6, then the equation now looks like 4 divided by 3(6).

3 x 6 = 18.

4 divided by 18 is .22 repeating.

This may be wrong. Check with another answer.
