Answer:
A = 8, B = 9 and C = 6.
Step-by-step explanation:
We can create equations to solve this:
6 + A = 14
So A = 8.
A + B = 17
8 + B = 17
B = 9.
C = 29 - (6 + A + B)
= 29 - ( 6 + 8 + 9)
= 29 - 23
= 6.
Answer:
SSS
∆PQR = 43
Step-by-step explanation:
The postulate to solve ∆PQR ≅ ∆STU is SSS. Both of the triangles have all three sides given, which means it can be solved for congruence.
9 + 6y + 5 + 14 = 9 + 8y +14
28 + 6y = 9 + 8y + 14
28 + 6y = 8y + 23
-6y -6y
--------------------------
28 = 2y + 23
-23 -23
---------------------
5 = 2y

2.5 = y
9 + 14 + 6(2.5) + 5
23 + 15 + 5
23 + 20
43
∆PQR = 43
Answer:
18
Step-by-step explanation:
If the average of 6 numbers is 10, then the sum of those 6 numbers is:
6 x 10 = 60
To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:
240 - 60 = 180
Therefore, the average of the 10 remaining numbers:
180 ÷ 10 = 18
180-149= 31
180-119-31=30
m<1=30
