Siince 2nd equation is already equal a, subsitute b-2 for a in the other equation

b-2-3b=28
-2-2b=28
add 2 to both sides
-2b=30
divide both sides by -2
b=-15
sub back
a=b-2
a=-15-2
a=-17

(a,b)
(-17,-15)

yuradex [85]

Answer:

C. 8, 15, 17

E. 15, 20, 25

Step-by-step explanation:

You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔

Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625

and 25x25=625 so 625=625 ✔

Hope this helped and good luck!

Points O, A, B lie on the same line. OA = 12 cm, OB = 9 cm. Find the distance between the midpoints of segments OA and OB if: Po
12345 [234]
Short Answer: 1.5
Givens
OA = 12
OB = 9
O does not lie on AB

Argument
The order that these lines must be in is OBA. O is on your left, B is in the middle and A is on your right. 

Mark your distances as follows.
OB = 9
BA = 3

Mark the midpoint of OA = M1
Mark the midpoint of OB = M2

M1 = 12 / 2 = 6 so M1 is 6 units from O
M2 = 9/2 = 4.5

The distance between the two midpoints is 6 - 4.5 = 1.5
Answer M1 - M2  = 1.5 <<<<

Nice problem: Thanks for posting.
