Suma a doua numere este 98 iar diferenta lor este 82 aflati cele doua numere​
Virty [35]

Answer:

90 and 8

Step-by-step explanation:

The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers

Let two numbers are x and y.

Sum of two numbers is 98

x+y = 98 ....(1)

The difference of two numbers is 82.

x-y=82....(2)

Adding equation (1) and (2) we get :

x+y+x-y=98+82

2x=180

x=90

Put the value of x in equation (1)

90+y = 98

y = 8

Hence, the two numbers are 90 and 8.

Points S,U, and T are the midpoints of the sides of PQR. Which statements are correct ? 1/2QP=UT 1/2TS=RQ SU=PR SU||RP UT=RP
steposvetlana [31]

Answer:

\frac{1}{2} QP = UT

Step-by-step explanation:

We are given  a ΔPQR  in which S is the mid point of QP  , T is the mid point of  QR , U is the mid point of PR

i) is true

⇒ \frac{1}{2} QP = UT

Using mid segment theorem which states that In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .

So, by refering image we can see that UT is the line joining the two mid points . So, by using above theorem    1/2QP=UT and UT is parallel to PQ

Thus, (i) statement is true

⇒\frac{1}{2} QP = UT
