4 A 7 2 + B 8 5 C + 9 2 D 6 = E 7 7 7 5 ? |
|
Answer» 4A72 + B85C + 92D6 = E7775 Let's write them decimally. Means writing the number in the form of 10x + y as x / y. (Not dividing) Here, 4A72 = 4 / A / 7 / 2 B85C = B / 8 / 5 / C 92D6 = 9 / 2 / D / 6 E7775 = E / 7 / 7 / 7 / 5 4 / A / 7 / 2 + B / 8 / 5 / C + 9 / 2 / D / 6 = E / 7 / 7 / 7 / 5 = 4 + B + 9 / A + 8 + 2 / 7 + 5 + D / 2 + C + 6 = E / 7 / 7 / 7 / 5 = B + 13 / A + 10 / D + 12 / C + 8 = E / 7 / 7 / 7 / 5 The ones DIGIT of C + 8 is 5. ∴ C + 8 = 15 C = 15 - 8 = 7 ∴ E / 7 / 7 / 7 / 5 = E / 7 / 7 / 6 / 15 The ones digit of D + 12 is 6. ∴ D + 12 = 16 D = 16 - 12 = 4 ∴ E / 7 / 7 / 7 / 5 = E / 7 / 6 / 16 / 15 The ones digit of A + 10 is 6. ∴ A + 10 = 16 A = 16 - 10 = 6 ∴ E / 7 / 7 / 7 / 5 = E / 6 / 16 / 16 / 15 Here, B + 13 = E / 6 ∴ B + 13 = E / 6 = 16 B = 16 - 13 = 3 E / 6 = 16 ∴ E = 1 A = 6; B = 3; C = 7; D = 4; E = 1 And the question given is actually, 4672 + 3857 + 9246 = 17775 Hope this may be helpful.

Triangle ABC, with coordinates A(2, 3), B(3, 5), C(7, 4), is dilated by a scale factor of 2. What are the coordinates of the dilated figure, triangle A′B′C′? |
|
Answer» Answer: The COORDINATES of the dilated figure, triangle A'B'C' would be A'(4,6), B'(6,10), and C'(14,8) Step-by-step EXPLANATION: For DILATION by a SCALE factor of 2, we need to multiply the coordinates by 2. So, The coordinate of A'= 2*(2,3)= (4,6) The coordinate of B'= 2*(3,5)= (6,10) The coordinate of C'= 2*(7,4)= (14,8) |
