Answer:

Below.

Step-by-step explanation:

RS ≅ TS    (given)

RV ≅ TV    ( as  V is the midpoint of RT).

VS is common to both triangles.

Therefore ΔRSV ≅ ΔTSV   (  three sides are equal ,  SSS).

Answer:

Look rs=ts then vs=vs they have it same then rv=vt because v is the midpoint of rt

Solve the system of linear equations by substitution.<br><br>−2x−5y=3<br> 3x+8y=−6
Sliva [168]
First you want to know what y or x is i chose y for this on 

so the equation i'm going to use is -2x-5y=3
i want to solve for y

-2x-5y=3
+2x        +2x

-5y=2x+3
 /-5   /-5  /-5
y=-2/5x+-3/5

Now that i solved for y we substitute our answer into the next equation to solve for x like this:

3x+8y=-6
3x+8(-2/5x+-3/5)=-6
3x+ -3.2x+-4.8=-6
-0.2x+-4.8=-6
          +4.8  +4.8
-0.2x=-1.2
/-0.2    /-0.2
x=6

After you know what x is you substitute it in for any of the equations that we started with. I picked 3x+8y=-6 to find y.

3x+8y=-6
3*6+8y=-6
18+8y=-6
-18      -18
8y=-24
/8     /8
y=-3

Since we know what x and y are we substitute it with any of the equations that we started with. i picked -2x-5y=3

-2*6-5*-3=3
-12- -15=3
3=3 
so our solution (6,-3) works

How can I calculate if a given decimal is rational or irrational. please help I forgot.
dalvyx [7]
Well, a rational decimal is like a simple 3.1 or 4.5. It just cuts off easily. Another example would be a repeating decimal like 3.333333...


An irrational decimal is like 3.1415682983523576294875 with no pattern or cutoff point.


Sorry if I am wrong.

No. of diners = 240
Musya8 [376]

Answer:

<u>We need to buy 3 cases of juice.</u>

Correct statement and question:

No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?

Source:

Previous question that you can search at brainly

Step-by-step explanation:

Let's calculate the number of cases of juice are required this way:

Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case

Replacing with the real values, we have:

Number of cases required = [(240 * 4)/48]/8

Number of cases required = [(960)/48]/8

Number of cases required = 20/8

Number of cases required = 2.5

<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>
