Question

6. Găseşte termenul necunoscut:
a) 437 x 104 + a = 53 480
2 306 x 204 + b = 601 459
dc-206 x 181 = 17500
348 x 5 103 - d = 63 429​

Answer 1

Răspuns:

a)437×104+a=53.480

45.448+a=53.480

a=53.480-45.448

a=8.032

b)2.306×204+b=601.459

470.424+b=601.459

601.459-470.424=b

b=131.035

c)dc-206×181=17500

dc-37.286=17500

dc=17500+37.286

dc=54786
