2b plus 4a minus a minus 2 plus 12b
jarptica [38.1K]

The value of the expression 2b plus 4a minus a minus 2 plus 12b is 3a + 14b - 2.

Expression:

An expression is defined as the a combination of operators, constants and variables. And it may consist of one or more operands, and zero or more operators to produce a value.

Given,

Here we have the statement "2b plus 4a minus a minus 2 plus 12b".

Now, we have to find the simplified form of this statement.

In order to find the simplified form,

First we have to convert the statement into expression form, then we get

2b plus 4a minus a minus 2 plus 12b = 2b + 4a - a - 2 + 12b

Now, we have to combine the like terms, then we get,

=> (2b + 12b) + (4a - a) - 2

Perform the appropriate arithmetic operations, then we get the simplified form of the expression as,

=> 14b + 3a - 2

Now, we have to arrange them in order then we get,

=> 3a + 14b - 2

To the nearest​ millimeter, a cell phone is 72 mm long and 46 mm wide. What is the ratio of the width to the​ length
earnstyle [38]

Answer:

Length = 72 mm

Width = 46 mm

Ratio = 72:46 = 36:23

Step-by-step explanation:

72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.

How many ways can 100 be written as the sum of distinct integers from the set {1, 2,..., 15}?
konstantin123 [22]

Answer:

48 ways

Step-by-step explanation:

Let me take a guess

S₁_₁₅ = (1+15)*7 + 8 = 120

There are 48 combinations of distinct digits from 1 to 15 to make 20

120-20=100

So every 20 has a corresponding 100

I wish I got it right, otherwise report it.

I can’t figure this out, any help?

if the spinner is fair , it will land on green for 60 times , there are 24% chances for the spinner to land on purple ,For 1000 spins it will land 150 times on blue

<h3>What is Probability ?</h3>

Probability can be defined as the study to predict the likelihood of an event.

It has a range from 0 to 1.

Probability if the spinner is fair is 1/5 for each colour.

As it is spun 300 times

(1/5) * 300 = 60 times

So if the spinner is fair , it will land on green for 60 times.

(b) The probability of landing on purple theoretically is 60times , 20 % chances

but it can be seen from the data provided that for 300 spins , the spinner landed for 72 times

which is 24% , i.e. there are 24% chances for the spinner to land on purple.

(c)Theoretically blue has 20% chances 200 times , But it is seen in the data obtained that

for 300 spins the spinner is landing on blue for 45 times.

For 1000 spins it will land 1000*45/300 = 150 times.
