Add in order from left to right:

-9 + 5 = -4

-4 -10 = -14

-14 + 3 = -11

False, it does not equal 2.

Answer:

False. It equals -11.

Step-by-step explanation:

Simply because if you add -10+3, you get -7. Then if you add -9 and 5, you get -4. when you add -4 and -7 together, you get -11.

Answer:

i beleive 2 2/3

Step-by-step explanation:

the change from 9 to 13.5 is 2/3

5/3 (the whole of 4 plus 2/3 of it) of 4 is 6 2/3

6 2/3=x+4

2 2/3=x

Hope it helps you☺️☺️

Step-by-step explanation:

-3(4x+3)+4(6x+1)=x+43-13x

or,-12x-9+24x+4=-12x+43

or,12x-5=-12x+43

or,12x+12x=43+5

or,x=48/24

so,x=4

The distance the person would walk in one hour given the distance walked in 15 minutes is 1/45 miles.

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

the distance walked in one hour = 1/3 ÷ 15

1/3 x 1/ 15 = 1/45 miles

IDK WHY ITS SPREAD APART

Answer:

I answered #1 on a previous question

2) A

Step-by-step explanation:

2) So the formula for consecutive integers is x+x+1+x+2 and so on.

So we know there are 6 integers so the final would be x+5.

so the sum of the final and the first is x+5+x=1

Simplify the equation and solve

2x+5=1

2x=-4

Divide 2 on both sides

x=-2

so -2 is the least Interger of all.

Check: Use the equation x+5 since it’s the greatest,  so since x is -2 subsitute and you’ll get -2+5 you'll get 3 and 3+-2=1

A,B is the answer of this question

Let y = ax²+bx+c then substitute all of orders. we'll be doing equations system.

[tex]a-b+c=0\\c=3\\a+b+c=2[/tex]

Ok we are at this.

Substitute c = 3 into equation 1 and equation 3.

[tex]a-b+3=0\\a-b=-3[/tex]

[tex]a+b+3=2\\a+b=2-3\\a+b=-1[/tex]

then addition and subtract for a-b = 3 and a+b = -1

[tex]a-b=-3\\a+b=-1\\2a=-4\\a=-2[/tex]

Therefore a = -2, substitute a = -2 in a-b+c=0 or a+b+c=2 but i'm doing a-b+c=0 one.

[tex]a-b+c=0\\\\-2-b+3=0\\-b+1=0\\-b=-1\\b=1[/tex]

Therefore b = 1, substitute both a, b and c into y=ax²+bx+c as we get,

[tex]y=-2x^2+x+3[/tex] #

Step-by-step explanation:

Let the size of their father's land be x.

The first born received x/4

The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8

The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8

3x/8 = 3hectares

3x = 24

x = 8.

. : The initial size of the parcel land was 8 hectares.

u bring 5x to the other side to be 2x+5x-3>11 ,

you take -3 to the other side to be 2x+5x>11+3

therefore it will be 7x>14 ,so you divide both sides with 7 to get

Solving in steps

Answer:

  (x, y, z) = (-3, 2, 5)

Step-by-step explanation:

Using the first equation, we can write an expression for x:

  x = 21 +3y -6z

Substituting this into the remaining two equations gives ...

  3(21 +3y -6z) +2y -5z = -30

  63 +9y -18z +2y -5z = -30

  11y -23z = -93

and

  2(21 +3y -6z) -5y +2z = -6

  42 +6y -12z -5y +2z = -6

  y -10z = -48

This second equation makes it easy to write an expression for y:

  y = 10z -48

Substituting that into the previous equation, we have ...

  11(10z -48) -23z = -93

  110z -528 -23z = -93

  87z = 435

  z = 5

  y = 10(5) -48 = 2

  x = 21 +3(2) -6(5) = -3

The solution is (x, y, z) = (-3, 2, 5).
