The distance an object has traveled when starting at an initial velocity is given by the equation: d = vit + atz. In the equation, v, represents the initial velocity, t represents the time traveled, and
a represents the acceleration. Solve the equation for a.

answer: what do you mean

c

step-by-step explanation:

i think because what else can be a sample of every member

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

b.   e = 7.5h

hope this , lovely!
