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,
18 - 6 (2 + 4 - 1 + 2) ÷ 3
Apply the PEMDAS rule.
P = Parenthesis
E = exponents
M = Multiplication
D = Division
A = addition
S = Subtraction
Step 1:
18 - 6 (8 - 1) ÷ 3 ( remove the parentheses )
18 - 6 x 7 ÷ 3
Step 2:
18 - 42 ÷ 3 ( Multiplication )
Step 3:
18 - 42/3 (Division)
18 - 14
Step 4:
18 - 14 ( Subtraction )

[tex]\mathrm {Is}[/tex] [tex]\sqrt[]{103}[/tex] [tex]\mathrm {irrational/rational?}[/tex]
We cannot write [tex]\sqrt{103}[/tex] as a ratio of integers, so that's why it's irrational.
Note that [tex]\sqrt{103} \approx 10.1488915650922[/tex]
The decimal digits go on forever without any pattern. If the digits repeated themselves, then we would have a rational number.
A quick way to tell if it is rational or not, without using a calculator, is to note that 103 is not a perfect square. The list of perfect squares are:
1,4,9,16,25,36,49,64,81,100,121,...
we see that 100 is the closest perfect square, but 103 is not in that list. Each perfect square is of the form x^2, where x is some positive whole number.
Answer:
Yes this is irrational like the guy above me said you cannot write it as a ratio, of integer since rational numbers are:
A rational number is any integer,
fraction,
terminating decimal,
or repeating decimal.
So its Not Rational

(15.2*0.25-48.51/14.7)/x=(13/44-2/11-5/66/2.50)1.2/(3.2+0.8(5.5-3.25)
Answer:
x = 41.67
Step-by-step explanation:
The above equation, would be simplified or divided into parts;
Therefore, the given equation becomes;
A/x = B/C
Where;
A = (15.2*0.25-48.51/14.7)
B = (13/44-2/11-5/66/2.50)1.2
C = 3.2+0.8(5.5-3.25)
x = unknown variable.
Part A
(15.2*0.25-48.51/14.7) = (15.2*0.25 - 3.3)
A = (3.8 - 3.3)
A = 0.5
Part B
(13/44-2/11-5/66/2.50)1.2 = (0.3 - 0.18 - 0.030) * 1.2
B = 0.09 * 1.2
B = 0.108
Part C
(3.2+0.8(5.5-3.25)
C = 4*(2.25)
C = 9
Substituting the values into the equation, we have;
0.5/x = 0.108/9
Cross-multiplying, we have;
9 * 0.5 = 0.108x
4.5 = 0.108x
x = 4.5/0.108
x = 41.67

At a hockey game, a vender sold a combined total of 156 sodas and hot dogs. The number of sodas sold was two times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
Answer: They sold 104 sodas and 52 hotdogs
Step-by-step explanation: If we represent sodas as x and hotdogs as y then x+y=156. There is twice as many sodas as hotdogs so x=2y. We can then substitute x for 2y so the equation would be 2y+y=156 or 3y=156. We divide both by three and get y=52 we plug that back in to the equation x=2y and we get x=104. We then check to make sure it is correct and get 104+52=156 and 104/2=52. Hope this helps.
