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, 16.87 + (–98.35) Thus using the BODMAS rule we get the sum as 16.87 + (–98.35) =-81.48
Hence, The sum of the expression is -81.48

Simplify completely
x2 + 4x - 45
and find the restrictions on the variable.
Answer:
(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!

Answer: inverse variation
Step-by-step explanation:
The type of function that best models the table is inverse variation. The correct option is A.
What is Inverse Variation?Inverse variation can be described as a relationship between two variables, whereby, the product of the two variables will give a constant. It is expressed as, k = xy.
In an inverse variation, if one variable increases, the other variable decreases.
The table shows an inverse variation because as x increases, y decreases, and can be expressed as k = xy.
Therefore, the type of function that best models the table given is: A. inverse variation.

Christina is packing different books into boxes. The paperback books weigh 0.8 pounds each. The hardcover books weigh 1.3 pounds each. Christina needs to pack the boxes so that there are at least 20 books in each box, but the boxes cannot weigh more than 30 pounds. Identify Christina's set of constraints. Check all that apply.
Answer:
[tex]x\geq0, y\geq0, x+y\geq20,[/tex] and [tex]8x+13y\leq300[/tex].
Step-by-step explanation:
Let x and y be the numbers of the paperback book and the hardcover book respectively.
as x and y are the counting numbers, so it will be always positive. So,
[tex]x\geq0\;\dots(i)[/tex] and
[tex]y\geq0\;\cdots(ii)[/tex]
Given that the weight of 1 paperback book=0.8 pounds and
the weight of 1 paperback book=1.3 pounds.
There are at least 20 books in each box, so
[tex]x+y\geq20\;\cdots(iii)[/tex]
As one box cannot weigh more than 30 pounds, so
[tex]0.8x+1.3y\leq30[/tex]
[tex]\Rightarrow 8x+13y\leq300\;\cdots(iv)[/tex]
Now, from the equations (i),(ii),(iii), and (iv), all the sets of constraints as
[tex]x\geq0, y\geq0, x+y\geq20,[/tex] and [tex]8x+13y\leq300[/tex].
Moreover, the sets of all the integral values of (x,y) in the shaded region are the feasible numbers of the paperback book and hardcover book.

c
5/8, 65%, 2/3, 0.7
d
5/8, 2/3, 65%, 0.7
Answer:
The answer is C
Step-by-step explanation:
5/8 = 0.625 , 65% = 0.65, 2/3 = 0.66 so
o.625 < 0.65 < 0.66 < 0.7
what is the value of y?
A. 56°
B. 68°
C. 44°
D. 112°
Answer:
The answer is option BStep-by-step explanation:
Since the figure above is a triangle all it's interior angles sum up to 180°.
To find y add up all the angles and equate them to 180 and solve for y
That's
y + y - 12 + 56 = 180
2y + 44 = 180
2y = 180 - 44
2y = 136
Divide both sides by 2
We have the final answer as
y = 68°Hope this helps you

What is the slope of the line 4x – 2y = 5? –4 –2 2 4
Answer:
it’s 2. Because you would subtract 4x and then get -2y=-4x+5. Then, you would divide -4 and -2 and get y=2x+5.
The slope of the linear equation or line 4x - 2y = 5 if 2 after converting the line into the standard form option (D) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation of linear equation is:
4x – 2y = 5
As we the slope-intercept form of the line is:
y = mx + c
Convert the linear equation into the above form:
2y = 4x - 5
y = 2x - 5/2
m = 2
Thus, the slope of the linear equation or line 4x - 2y = 5 if 2 after converting the line into the standard form option (D) is correct.
