Question

Given that v = u + 10t, find v when u = -21 and t = 7

Answer 1

Answer: 49

Explanation:

You have to start by plugging in -21 where U is and 7 where t is

After you do this your equation will be (-21)+10(7)

Use PEMDAS and you will have -21+70

Which equals 49

I hope this helps!

Answer 2

v = 49, (when u = -21 & t = 7)

Explanation:

Given equation,

→ v = u + 10t

Now we have to use,

→ u = -21

→ t = 7

Then the value of v will be,

→ v = u + 10t

→ v = (-21) + 10(7)

→ v = -21 + 70

→ [ v = 49 ]

Hence, the value of v is 49.
