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.

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

Find the distance between each pair of points. Round to the nearest tenth
(-2,2) (5,2)
Answer:
Distance = 7
Step-by-step explanation:
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(5-(-2))^2+(2-2)^2} \\d= \sqrt{(7)^2+(0)^2} \\d= \sqrt{49+0} \\d= \sqrt{49}\\ d= 7[/tex]

Find the measure of an angle if its measure is 26 degrees more than three times its compliment?
16
141
74
42
The complement = x
The angle we are finding = 3x + 26
Complementary angles are angles that add up to 90 degrees.
90 = x + 3x + 26
Combine like terms
90 = 4x + 26
Subtract 26 from both sides
64 = 4x
Divide both sides by 4
16 = x
The angle we are trying to find = 3(16) + 26 = 48 + 26 = 74 degrees

Paran had $85.58. He bought a book for $24.98 and a pack of pens for $2.49.
About how much money does Paran have left?
Between $55.50 and $57.50
Between $57.50 and $59.50
Between $59.50 and $61.50
Between $61.50 and $63.50
Onestion 7
2 nits
Y
Answer:
Between $59.50 and $61.50
Step-by-step explanation:
Since this is about, we have to round the numbers.
85.58 is rounded to 86
24.98 is rounded to 25
2.49 is rounded to 2.50
Therefore:
86 - 25 - 2.50 = 59.50
So the correct answer is #3

1) d=25 2) d=2[tex]\sqrt{2}[/tex] 3) d=[tex]13\sqrt{2}[/tex]
Step-by-step explanation:
[tex]d=\sqrt{(-2-1)^2+(-2-2)^2}\\ d=\sqrt{(-3)^2+(-4)^2} \\d=\sqrt{(-9)+(-16)}\\d=\sqrt{-25} \\d=5[/tex]
[tex]d=\sqrt{(5-3)^2+(-4-(-6))^2}\\ d=\sqrt{(2)^2+(2)^2} \\d=\sqrt{(4)+(4)}\\d=\sqrt{8} \\d=2\sqrt{2}[/tex]

At the Tucson Zoo, Jason spends $6.00 to enter the zoo and $2.00 per animal to feed them. Meanwhile, at the Phoenix Zoo, Kim spends $15.00 to enter and $1.00 per animal to feed them.The equation 6 + 2x = 15 + x represents this situation. How many animals do they need to feed in order to spend the same amount?

3x = 9
2. divide both sides by 3
3x/ 3 = 9/3x = 3Is 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
