Question

Составь верные равенства и неравенства, используя выражения на карточках 21 + 29 160-90 328-258 150+40 250- 50 98+102 33+367 900-450

Answer 1

250-50=98+102 21+29 <160-90

Answer 2

21 + 29 = 50

160 - 90 = 70

328 - 258 = 70

150 + 40 = 190

250 - 50 = 200

98 + 102 = 200

33 + 367 = 400

900 - 450 = 450

Now, let's use these expressions to create some equations and inequalities:

Equations:

1. 21 + 29 = 50 2. 160 - 90 = 70 3. 328 - 258 = 70 4. 150 + 40 = 190 5. 250 - 50 = 200 6. 98 + 102 = 200 7. 33 + 367 = 400 8. 900 - 450 = 450

Inequalities:

1. 21 + 29 > 160 - 90 2. 328 - 258 < 150 + 40 3. 250 - 50 = 98 + 102 4. 33 + 367 < 900 - 450

These equations and inequalities can be used to solve for unknown variables or to compare different expressions. Let me know if you have any specific questions or if there's anything else I can help you with!
