Answer:
• [tex]b = \bf 100[/tex]
• [tex]d = \bf 22[/tex]
Step-by-step explanation:
To solve these questions, we need to rearrange the equations to make the unknown variables the subject of the equations.
1a.
[tex]\frac{b}{46} = \frac{50}{23}[/tex]
⇒ [tex]b = \frac{50 \times 46}{23}[/tex] [multiplying both sides by 46]
⇒ [tex]b = \bf 100[/tex]
1b.
[tex]\frac{34}{d} = \frac{68}{44}[/tex]
⇒ [tex]34 = \frac{68 \times d}{44}[/tex] [multiplying both sides by d]
⇒ [tex]34 \times 44 = 68 \times d[/tex] [multiplying both sides by 44]
⇒ [tex]\frac {34 \times 44}{68} = d[/tex] [dividing both sides by 68]
⇒ [tex]d = \bf 22[/tex]
