Answer:
4 is the number.
Step-by-step explanation:
Take the missing number as x,
→ (x × 3) - 4 = (x × 2)
→ 3x - 4 = 2x
→ 3x = 2x + 4
→ 3x - 2x = 4
→ [ x = 4 ]
Hence, the number is 4.
Answer:
S (1 , 0)
T (7 , 1)
Step-by-step explanation:
If QRST is a parallelogram, P is the mid point of segment QS and segment RT.
Basic formula for mid-point of segment: ((x1+x2)/2 , (y1+y2)/2)
T (x₁ , y₁) S (x₂ , y₂) P (2 , 3) Q (3 , 6) R (-3 , 5)
2 = (x₁ + (-3))/2 x₁ = 7
3 = (y₁ + 5)/2 y₁ = 1
T (7 , 1)
2 = (x₂ + 3))/2 x₂ = 1
3 = (y₂ + 6)/2 y₂ = 0
S (1 , 0)
If you are just adding those two decimals together, the answer would be 100.871.
83.971
+ 10.900 (make believe there are two zeros)

100.871
true because integers are all positive numbers, their opposites (negatives), and zero
