Answer 1

Answer: If 1 inch represents 0.5 centimeter, then 28 inches will represent 28 * 0.5 = 14 centimeters and 15 inches will represent 15 * 0.5 = 7.5 centimeters.

The actual dimensions of the phone is: the length is 14 centimeters and the width is 7.5 centimeters.

Proper inverse operation 14 + 17 = 31

Answers

subtraction is the correct inverse operation because you want one number on one side and the others on the other side and since both 14 and 17 are positive you need to subtract to get them to the right side

Answer:

No inverse operation needed. There are no varables to solve for.

Winnie write the following riddle.I am a number between 60 and 100.My ones digit is teo less than my trns digit.I am a prime number.Winnie's friend Marci guessed that her riddle was about the number 79.Why can't 79 be the answer to Winnie's riddle?

Answers

The criteria is
Between 60 & 100
Units digit 2 less than tens
Prime number

79 is a number between 60 & 100 and it is a prime number (as its only factors are 1 and itself), however 79 has a tens digit that is 2 less than the units - not the units 2 less than the tens.
As it does not comply with one of the rules the number cannot be 79

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Threenumbers:

First = a

Second = b

Third = c

Now,

a + b + c = 126 ____(1)

c = 4b ____(2)

b = a - 6 _____(3)

From (1), (2), and (3) we get,

a + (a - 6) + 4b = 126

a + a - 6 + 4b = 126

2a + 4b = 126 + 6

2a + 4b = 132

2a + 4(a - 6) = 132

2a + 4a - 24 = 132

6a = 132 + 24

6a = 156

a = 26

Now,

a = 26

b = a - 6 = 20

c = 4b = 4 x 20 = 80

Thus,

The numbers are 26, 20, and 80.

Lets define a=1st number, b=2nd number, and c=3rd number

We know that a+b+c=126

We also know that the second number is 6 more than the first, so we can represent this as b=a+6

We also know that the third number is 3 times the first which can be represented as c=3a

We can plug these new values into our original equation and get:

a+(a+6)+(3a)=126

2a+6+3a=126 COMBINE LIKE TERMS

5a+6=126

5a=120

a=24

Our first number is 24.

Our second number is 6 more than our first number, so the second number is 24+6=30

Our third number is 3 times the first number, so the third number is 3(24)=72

We can check by plugging these numbers in for a, b, and c in our original equation

a+b+c=126

24+30=72=126

126=126
