Answers

Answer:

the one clue you have is "30,12" on the left. try to understand how they relate to each other. maybe how many times 12 goes into 30. or maybe how many times it goes into 32 with no decimal so what number do you have to add (sometimes work doesnt mean it like that so that might be wrong). but if you want the answers, they are:

35/5/15/30

14/2/6/12

the way i did it was if it was on the bottom (y) i did 2.5 times the number. if on the top (x) i did the number divided by 2.5. 2.5 was the rate of change (is that the word i think it is but if it isnt just blame me im sorry).

Step-by-step explanation:

Is 9/12. Bigger than 3/4?

Answers

No it is the same and u will tell is u simplify 9/12 down 
No,9/12 is equal to 3/4 because when you find the LCM of the number it is three then you multiply the number to 3/4 and you get 9/12.



or 9/12 is = to 3/4

a=7/2-3/10

Step-by-step explanation:

20a +158+6c= 120+60+48

20a +158+6c=228

20a =228-158-6c

20a =70-6c

a= 7/2 - 3/10

Answer:

120 + 60 + 48 would be the correct answer !

1) 1st integer = x ; 2nd integer = x + 1
x + x + 1 = 73
2x = 73 - 1
2x = 72
2x/2 = 72/2
x = 36  
1st integer = x = 36
 2nd integer = x + 1 = 36 + 1 = 37

2) 1st integer = -x ; 2nd integer = -x + 1
-x + -x + 1 = -171
-2x +1 = -171
-2x = -171 - 1
-2x = -172
-2x/-2 = -172/-2
x = 86     
1st interger = -86 ;
2nd integer = -86 + 1 = -85  (integer closest to zero)

3) 1st integer = x ; 2nd integer = x + 1 ; 3rd integer = x + 2
x + x+1 + x+2 = 78
3x + 3  = 78
3x  = 78 - 3
3x = 75
3x/3 = 75/3
x = 25
1st integer = x = 25     (integer closest to zero)
2nd integer = x + 1 = 25 + 1 = 26
3rd integer = x + 2 = 25 + 2 = 27

4) 1st integer = x ; 2nd integer = x + 1 ; 3rd integer = x + 2
x + x+1 + x+2 = 261
3x + 3 = 261
3x = 261 - 3
3x = 258
3x/3 = 258/3
x = 86
1st integer = x = 86
2nd integer = x + 1 = 86 + 1 = 87 (middle number)
3rd integer = x + 2 = 86 + 2 = 88

5) 1st integer = -x ; 2nd integer = -x+1 ; 3rd integer = -x + 2
-x + -x+1 + -x+2 = -165
-3x + 3 = -165
-3x = -165 - 3
-3x = -168
-3x/-3 = -168/-3
x = 56
1st integer = -x = -56
2nd integer = -x+1 = -56 + 1 = -55
3rd integer = -x+2 = -56 + 2 = -54 (closest to zero)

What the solution set (x+9)^2=169 of this quadratic equations by extracting the roots? ​

Answers

Answer:

x = - 22, x = 4

Step-by-step explanation:

Given

(x + 9)² = 169 ( take the square root of both sides )

x + 9 = ± √(169) = ± 13 ( subtract 9 from both sides )

x = - 9 ± 13

Thus

x = - 9 - 13 = - 22

x = - 9 + 13 = 4

The question is in the picture.
