The calculation 18/6=108 is not the right representation.
What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here: One of the option as 18/6=108
But in the question Jenna buys 6 new shirts at $18
Thus the total cost of the shirts is 18*6=108
But 18/6=3
Thus this expression is not the right calculation.
Hence, The 18/6=108 is not the right representation.

Step-by-step explanation:
i answered the question:)
Using number sets, it is found that the number -5 belongs to these following sets:
Integer numbers.Rational numbers.Real numbers.----------------------------------
Numbers are classified as:
Whole numbers: Set of numbers including all positive numbers and 0, so: {0,1,2,...}. This set is also called natural. Integer numbers: Number without decimals, that can be positive or negative, so: {...,-2,-1,0,1,2,....} Rational numbers: Integer plus decimals that can be represented by fractions, that is, they either have a pattern, or have a finite number of decimal digits, for example, 0, 2, 0,45(finite number of decimal digits), 0.3333(3 repeating is the pattern), 0.32344594459(4459 repeating is the pattern). Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339. Real numbers: Rational plus irrational.----------------------------------
-5 is a negative number, so it is integer.All integers are rational and real, and thus, -5 is integer, rational and real.A similar problem is given at https://brainly.com/question/10814303
6.8x+9.3 = -9.4+3,4(2-5x)
6.8x+9.3 = -9.4+6.8 -17
6.8x+9.3 = -2.6-17x
Answer:
x = -0.5
Step-by-step explanation:
From your last step:
6.8x + 9.3 = -2.6 - 17x
We have two terms with x in them on different sides of the equation, so we want to bring the 'x terms' over to the same side.
Add 17x to both sides of the equation.
6.8x + 17x + 9.3 = -2.6
Collect like terms
23.8x + 9.3 = -2.6
Subtract 9.3 from both sides
23.8x = -2.6 - 9.3
23.8x = -11.9
Divide both sides by 23.8
x = -0.5

Answer:
x= -12
Step-by-step explanation:
∠2= (180°-36°)÷2 (base ∠s of isos. △)
∠2= 72°
m∠2= x +84
72= x +84
x= 72 -84
x= -12
Answer:
The value if x is -12.
Step-by-step explanation:
Given that isosceles triangle have a same pair of angle. So in order to find the angles, you have to subtract it from 180° and 36°.
[tex]θ + θ + 36 = 180[/tex]
[tex]2θ = 180 - 36[/tex]
[tex]2θ = 144[/tex]
[tex]θ = 144 \div 2[/tex]
[tex]θ = 72[/tex]
Next, the expression for ∠2 is x + 84 which is also 72°. So you have to solve it by comparing :
[tex]x + 84 = 72[/tex]
[tex]x = 72 - 84[/tex]
[tex]x = - 12[/tex]

Answer:
$4.76
Step-by-step explanation:
It costs $2.80 to make a sandwich at the local deli shop and the deli sells it at a price that is 170% of the cost.
We have to find 170% of the cost of making each sandwich ($2.80):
170/100 * 2.80 = $4.76
The sandwich sells for $4.76

How many real solutions does the equation 8x^2 − 10x + 15 = 0 have?
Answer:
It has no real solutions.
Step-by-step explanation
Once you calculate the discriminant, D= (-10)^2 -4 (8)(15), you simplify the expression to get D= -380, which has no real solutions.
Answer:
No solutions
Step-by-step explanation:
Quadratic equations are in the form of ax^2+bx+c, so a = 8, b= -10, and c = 15.
Use b^2 - 4ac to find the discriminant.
-10^2 - 4(8)(15) = -580
If a discriminant is < 0 then there are no real solutions to a quadratic equation. -580 < 0
Therefore, there are no real solutions

x + 13 = 34
A. X = 47
B. x= 19
o
C. x = 27
D. x= 21
SUBM
Answer:
21
Step-by-step explanation:
since we are looking for the value of x, we make it the subject of the formula(stand alone) and to do that + 13 would have to cross over the equality sign.when a positive number crosses over the equality sign it changes to a negative number .
Therefore,x +13=34
x=34 -13
x=21(d)

Given that,
The number of newly reported crime cases in a county in New York State is shown in the accompanying table,
Where x represents the number of years since 2001, and y represents number of new cases.
We have to determine,
The linear regression equation that represents this set of data.
And Using this equation, find the projected number of new cases for 2013.
According to the question,
The line of best-fit is given by:
[tex]y = bx+a[/tex]
Assume [tex]y = kx + b[/tex]
And,
[tex]k = \dfrac{change \ in \ y} {change \ in \x }\\\\k = \dfrac{1194-1086}{5-0}\\\\k = \dfrac{108}{5}\\\\k = 21.6[/tex]
Then, pass from the point (3, 1158),
[tex]y = kx + b \\\\1158 = 21.6 \times 3 + b \\\\1158 = 64.8 +b \\\\b = 1158 - 64.8\\\\b = 1093.2[/tex]
Then ,
The projected number of new cases - the number of years since 2001
[tex]= 2013-2001 \\\\= 12[/tex]
Therefore,
[tex]y = 21.6\times 12 + 1093.2\\\\y = 259.2 + 1093.2 \\\\y = 1352.4\\\\y = 1352 \ approx[/tex]
Hence , The required linear regression equation is [tex]y = 21.6x + 1093.2[/tex].
And The projected number of new cases for 2013 is 1352.
