Hizi hapa suluhisho za maswali yako: 8. A farmer has n cows and m goats in his farm. If he sells 5 of his cows, which algebraic expression represents the total remaining animals? Step 1: Tambua idadi ya awali ya ng'ombe na mbuzi. Idadi ya ng'ombe = n Idadi ya mbuzi = m Step 2: Pata idadi ya ng'ombe waliobaki baada ya kuuza 5. Ng'ombe waliobaki = n - 5 Step 3: Andika usemi wa aljebra unaowakilisha jumla ya wanyama waliobaki. Jumla ya wanyama waliobaki = (Ng'ombe waliobaki) + (Idadi ya mbuzi) Jumla ya wanyama waliobaki = (n - 5) + m Jumla ya wanyama waliobaki = n - 5 + m Jibu sahihi ni B. n - 5 + m. 9. Convert the decimal number 0.45 into a fraction and then reduce it to its simplest form. Step 1: Badilisha desimali kuwa sehemu. Desimali 0.45 inamaanisha arobaini na tano ya mia. 0.45 = (45)/(100) Step 2: Rahisisha sehemu kwa kutafuta kigawanyo kikubwa zaidi (GCD) cha namba ya juu na namba ya chini. Kigawanyo kikubwa zaidi cha 45 na 100 ni 5. Step 3: Gawanya namba ya juu na namba ya chini kwa kigawanyo chao kikubwa zaidi. (45 ÷ 5)/(100 ÷ 5) = (9)/(20) Jibu sahihi ni B. (9)/(20).
