Which expression is equivalent to 3m+1-m?
Lisa [10]

Answer:

option  (a) is correct.

2 + m - 1 + m is an equivalent expression  to the given expression  3m+1-m

Step-by-step explanation:

 Given expression  3m+1-m

We have to choose an equivalent expression from given options.

Equivalent expression are those expression that looks different but are same.

Like 4+2 = 6  and 3+ 3 = 6

Both have same value but looks differently.

Like terms are term having same variable with same degree.

Consider the given expression  3m+1-m

Simplify by adding like terms,

3m + 1 - m = (3-1) m + 1

Thus, (3-1) m + 1  = 2m + 1

Also 2m + 1 can be written as m + m + 2 - 1

Thus, option  (a) is correct.

A train has 6 identical passenger cars that are each 18 m long.
Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m
