Explain how to simplify the expression -98 - 31? Using the additive inverse.
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.
Can someone solve these please using the formula AB | a - b |
And can you show work
Answer: 1) AC = 13
The formua does not actually apply to all of the problems.
Step-by-step explanation:
1) The absolute value of -8 is added to the absolute value of 5. 8+5=13
2) Subtract the length of the EF from EG to get the length of FG 21 -6 = 15
3) Take what's given and create an equation to solve. 4x + 15 +39 =110. 4x = 110 - (15+39).
4x =110-54. 4x =56. x=56/4. x=14
4) Create another equation. You have two segments that add up to the length of EG, given =23
EF+FG=EG
(2x-12)+(3x-15)=23
5x - 27 = 23
5x= 23+27 5x =50. x = 10
Substitute 10 for x
EF=2(10) -12 EF=8
FG=3(10)-15. FG=15
EF+FG =EG.
8 + 15 = 23
5) 2/5 of 25 is 10 So EF is 10. Subtract from 25 to get FG
FG = 15
I hope this helps you.

grade 7. i actually already learnt this but this whole quarantine thing made me forget lolz. what are factors?
example : is 3 a factor of 372?
please answer and explain <3
Answer:
A number in a multiplication equation that makes up the total. For example,
2 x 3= 6.
2 and 3 are the factors.
Answer:
A factor is basically a number that derives from another without leaving a remainder. It sounds somewhat confusing when put into words but I'll give you some examples.
Step-by-step explanation:
in the problem you stated the answer would be yes. 3 is a factor of 372 because you can multiply 3 times another number (which in this case is 124) to get 372.
In addition, a number can have several factors. For example, these are all the factors for the number 10: 1, 2, 5, 10
notice how all these numbers multiplied by another of these same numbers on the list give you 10.
hope this helped :)

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]
solve 5p-1=9 by transposing method ? please help me friends....
Transposing means doing the same thing to each side to find an unknown value.
5p - 1 = 9
Add 1 to both sides.
5p = 10
Divide both sides by 5
p = 2
Answer:
2
Step-by-step explanation:
5p - 1 =9
5p =9 +1
5p =10
p=10 :5
p=2

What value of x makes this equation true?
3(x + 4) = 7x - 18
O x = 5
O x = 4.5
O x = 34.5
0 x = 75.
Answer:
x = 15/2 or x = 7.5
Step-by-step explanation:
Step 1: Write equation
3(x + 4) = 7x - 18
Step 2: Solve for x
Distribute 3: 3x + 12 = 7x - 18
Subtract 3x on both sides: 12 = 4x - 18
Add 18 on both sides: 30 = 4x
Divide both sides by 4: x = 15/2 or x = 7.5
Is 39,052 divisible by 3?
Answer:
no as the answer would be a decimal
Step-by-step explanation:
an easier way to know is to add up all the digits
3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3
this works for any number that should be divided by 3
example
is 2345 divisible by 3
2+3+4+5 =14 so no it is not divisible by 3
example
is 12345 divisible by 3
1+2+3+4+5 =15 so yes it is divisible by 3
hope this helps

Steve Fossett completed the first solo balloon circumnavigation of the world after 13.5 days. Assuming the balloon travelled along a circle of diameter 12 750 km, roughly what was the average speed of the balloon in km/h?
A) 12
B) 40
C) 75
D) 120
E) 300
Answer:
B) 40
Step-by-step explanation:
Average speed = distance/time
Distance = 12750 km
Time = 13.5 days = 13.5*24 hours = 324 hours
Speed = 12750 km /324 h = 39.4 km/h ≈ 40 km/h
Correct option is B) 40

B is between A and C. If AB = 7x - 2, BC = 3x + 1 and AC = 59, Find AB
Answer:
AB = 40Step-by-step explanation:
B is between A and C so:
AB + BC = AC
7x - 2 + 3x + 1 = 59
10x - 1 = 59
+1 +1
10x = 60
÷10 ÷10
x = 6
AB = 7x - 2 = 7×6 - 2 = 42 - 2 = 40
