Answer:
k = 3.75
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, k. Divide -1.2 from both sides:
(-4.5)/(-1.2) = (-1.2k)/-1.2
-4.5/-1.2 = k
k = -4.5/-1.2
k = 3.75
3.75 is your answer for k.

A = 2.5x , where x = 7 since there is 7 days in a week. So it would be 2.5(7)
B = 2.5(30) where 30 represents how many days. So he eats 75 cookies in 30 days.
Correct me if I am wrong.
If they took 2/3 away you have 1/3 left. you would have 7 left.
Take bus=5 times walk
b=5w
b+w=24
sub 5w for b
5w+w=24
6w=24
divide both sides by 6
w=4
sub back
b=5w
b=5(4)
b=20
bus-walk=20-4=16
answer is 16 more take the bus than walk

Step-by-step explanation:
For every question that comes your way, the first step is to understand the question.
The next, is to convert the word problems into algebraic expressions.
Lastly, you solve the expression accordingly.
Take for instance.
Ade has half a dozen eggs. How many dozen does Ade have?
We understand that; half means ½ and a dozen means 12.
So, the expression is
½ * 12 = 6 eggs
