Question

write an equation that represents the relationship between the variables in the table. options: d=10t, t=10 - d, t=d - 9, d=t + 10

Explanation:

Step1: Test first pair (t=1,d=10)

Check each equation:

• $d=10t$: $10=10\times1=10$ ✔️
• $t=10-d$: $1=10-10=0$ ❌
• $t=d-9$: $1=10-9=1$ ✔️
• $d=t+10$: $10=1+10=11$ ❌

Step2: Test second pair (t=2,d=20)

Check remaining equations:

• $d=10t$: $20=10\times2=20$ ✔️
• $t=d-9$: $2=20-9=11$ ❌

Step3: Verify third pair (t=3,d=30)

Check $d=10t$: $30=10\times3=30$ ✔️

Step4: Verify fourth pair (t=4,d=40)

Check $d=10t$: $40=10\times4=40$ ✔️

Answer:

d=10t
