Given:
The expression is -98 - 31.
To find:
The value of the given expression using the additive inverse.
Solution:
According to the additive inverse, for any number a,
[tex]a+(-a)=0[/tex]
Using additive inverse, we have
[tex]98+(-98)=0[/tex] ...(i)
[tex]31+(-31)=0[/tex] ...(ii)
Now, using (i) and (ii), we get
[tex]98+(-98)+31+(-31)=0[/tex]
[tex](98+31)+(-98-31)=0[/tex]
[tex]129+(-98-31)=0[/tex]
Subtracting 129 from both sides, we get
[tex]-98-31=-129[/tex]
Therefore, the value of given expression is -129.

Step-by-step explanation:
If A is an odd integer and B is an odd integer, is A*B sometimes, always, or never odd? Explain
Answer:
Always
Step-by-step explanation:
In order for an integer to be even, one of the factors must be 2. Otherwise, it is odd.
If A is an odd number, it does not have a factor of 2.
If B is an odd number, it also does not have a factor of 2.
Therefore, AB also does not have a factor of 2, so it is always odd.

Answer:
D
Step-by-step explanation:
y2 is the y to the right, and -6 is to the right of -8 on the x-axis, so (x2, y2) = (-6,52). plug in the values and you get (52-48)/(-6--8), which equals 4/2, which simplifies to 2.

A circle has a radius of 7 inches. What is the area of the circle? Use 3.14 for p.
(Area of a circle = pr2)
Answer:
The answer is
153.86 sq. inchesStep-by-step explanation:
Area of a circle is given by
A = πr²where r is the radius of the circle
From the question
r = 7 inches
So the area of the circle is
A = 3.14(7)²
= 3.14 × 49
We have the final answer as
153.86 sq. inchesHope this helps you
Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14
We know,
Area of the circle = πr²Here,
π = pi (An irrational number used for curves)r = radius of the circleSo, let's find the area,
➝ Area of the circle = πr²
➝ Area of the circle = 3.14 × 7²
➝ Area of the circle = 3.14 × 49
➝ Area of the circle = 153.86 inch²
Hence, Area of the circle:
[tex] \huge{ \boxed{ \bf{153.86 \: {inch}^{2} }}}[/tex]
And we are done !!

When Mya looked out at the store's parking lot, she noticed that for every 4 cars, there were 6 trucks. If there's a total of 220 vehicles in the parking lot, how many of them are cars, and how many of them are trucks?
Answer:
88 cars132 trucksStep-by-step explanation:
This is a ratio problem, the ratio of cars to trucks
for every 4 cars, there are 6 trucks
represented as a ratio we have 4:6
1. how many of them are cars
applying the part to whole strategy we have
4+6 = 10
let cars be x
[tex]\frac{4}{10}= \frac{x}{220} \\\\x= \frac{220*4}{10} \\\\x= 880/10\\\\x= 88 cars[/tex]
2. how many of them are trucks?
let trucks be y
[tex]\frac{6}{10}= \frac{y}{220} \\\\x= \frac{220*6}{10} \\\\y= 1320/10 \\\\y= 132 trucks[/tex]
what is the value of x if segment BC is 2x+4 and line Ac is 24
Greetings from Brasil
Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).
From the attached drawing we can conclude that:
AB + BC = AC
where
AB = Y
BC = 2X + 4
AC = 24
then
AB + BC = AC
Y + (2X + 4) = 24
X = (20 - Y)/2In my view this question is incomplete
Write an algebraic expression for each verbal expression: 1.) The product of 5 and twice a number x, decreased by the product of 3 and that same number. 2.) Twice the sum of a number x, and another number y, increased by the product of the first number squared and 8
Answer:
1) (5 times 2x) - (3 times 2x)
2) x+y) times 2 + (x*2 times 8)
explanation:
for "times" put a multiplication sign and the astric ( * ) is for the exponent or meaning "to the power of" :)
The first equation will be formed as: [tex](5 times 2x) - (3 times 2x)[/tex]
The second equation will be performed as [tex](x + y) times\ 2 + (x*2 \ times 8)[/tex]
What is multiplication?When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however other symbols like the "*" sign are also occasionally used.
1.) The composition of 3 and that identical number, multiplied by 5, lowered by the products of 5, and double that amount will be represented as (5 times 2x) - (3 times 2x)
2.) The product of the square root of the first variable and eight times a quantity x and a quantity will be represented as (x+y) times 2 + (x*2 times 8)

Answer:
Value of [tex]x[/tex] :
[tex]x = -\frac{2}{5}[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex] :
[tex]-25x = 10[/tex]
-Take [tex]25x[/tex] and divide it on both sides of the equation:
[tex]\frac{-25x}{-25} = \frac{10}{-25}[/tex]
[tex]x = -\frac{2}{5}[/tex]
So, the value of [tex]x[/tex] is [tex]-\frac{2}{5}[/tex].
M is the midpoint of RT. RM = 5x + 9 and MT = 8x - 36. Find x, RM, MT, and RT. = .
The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.
What is a System of equations?simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equations Where RM = 5x + 9 and MT = 8x - 36.
Since,
M is the midpoint of RT
Thus,
RM = MT
5x + 9 = 8x - 36
3x = 45
x = 15
So,
1) RM = 5x + 9
RM = 75 + 9 = 84
2) MT = 8x -36
MT = 120 - 36 = 84
3) RT = RM + MT
RT = 84 +84 = 168
Therefore, The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.

A solution of salt and water contains 70 grams of water per 140 milliliters of the solution. If 1 mole of water weighs 16 grams, moles of water would be present in 35 milliliters of the solution. [Round off your answer to two decimal places] (4 points)
Answer:
1.09 moles.
Step-by-step explanation:
There is 70g of water in 140ml of solution.
This means there are 17.5g of water in 35ml of solution. (Divide by 4)
In 17.5g of water, there are 17.5/16 = 1.09 moles of water.

Answer:
D. [tex]y = 2x[/tex]
Step-by-step explanation:
A proportional relationship is represented by the formula [tex]y = mx + b[/tex].
m = the slope, which is [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex].
b = the y-intercept, the point where the line crosses the y-axis. We actually don't have to worry about the [tex]+ b[/tex] part of the formula because [tex]b = 0[/tex], so it can be left out.
To find the slope, use [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex]. Subtract the smaller y value (2) from the larger y value (6).
(6 - 2 = 4)
Then subtract the smaller x value (1) from the larger x value (3).
(3 - 1 = 2)
So it looks something like this now:
[tex]\frac{6-2}{3-1}[/tex] , which equals [tex]\frac{4}{2}[/tex]
Then you divide the top part of the fraction (4) by the bottom part. (2).
[tex]\frac{4}{2}[/tex] = 2. The slope (m) is 2.
So the final equation is [tex]y=2x[/tex].
