Answer:

2.3 ×  is 20,000 times greater than 1.15 ×

Step-by-step explanation:

Given as :

The first number= x = 2.3 ×

The second number= y = 1.15 ×

Let The first number is z times greater than second number

i.e x = z × y

Or, z =

Or, z =

Or, z = 2 ×

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 ×  is 20,000 times greater than 1.15 ×

Answer:

b2−b+4

Step-by-step explanation:

Write the problem as a mathematical expression.

(2b2−6)+(4b+7)−(b2+5b−3)(2b2-6)+(4b+7)-(b2+5b-3)

Remove parentheses.

2b2−6+4b+7−(b2+5b−3)2b2-6+4b+7-(b2+5b-3)

Simplify each term.

2b2−6+4b+7−b2−5b+32b2-6+4b+7-b2-5b+3

Simplify by adding terms.

b2−b+4

2. do the same for the others and select the highest number

Answer:

Should be something along the lines of:

3,450 = 326x - 310

Step-by-step explanation:

First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.

Hope this helps!! : )

Sorry if I am wrong, haven't done equations in a while.

Answer:

Perpendicular

Step-by-step explanation:

For this problem, it is important to note two things.  One line is completely vertical, and the other line is completely horizontal.

The line y=9 is completely horizontal at the y-value at 9.  The line x = 2 is completely vertical at the x-value at 2.

Hence, these two lines would be perpendicular.

Cheers.

Answer:

Perpendicular.

Step-by-step explanation:

Since it makes a huge cross +, which we want it to be, we need the lines to intercept and it makes a right angle. That means it is perpendicular.

Answer:

{x,y} = {33/19,-2/19}

Step-by-step explanation:

Answer: For 5x-3y=-11, the answer is y=11/3 + 5x/3.

For 2x-5y=-14, the answer is y=14/5 + 2x/5

Step-by-step explanation: Move all terms that do not contain y to the right side and then solve.

I hope this helps you out! :)

Answer:

[tex]m=-1[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

[tex]m=\frac{0-6}{4-(-2)}[/tex]

[tex]m=\frac{-6}{4+2}[/tex]

[tex]m=\frac{-6}{6}[/tex]

[tex]m=-1[/tex]

Answer:  A segment bisector, always passes through the midpoint of the segment and divides a segment in two equal parts. Points, lines, segments, and rays are all types of segment bisectors. If either a ray or a line serves as a segment bisector, it will be infinite.

Answer:

-3/2 or -1.5

Step-by-step explanation:

1) Write out the numbers:

-9, -8, -7, -6, -5, -4, -3, [-2, -1] 0, 1 , 2, 3, 4, 5, 6

2)-2 and -1 are in the middle

3)Add the numbers in the middle and divide by 2

Answer:

(12 + 3x)x

Step-by-step explanation:

(12 + 3)x = 12x + 3x = 15x

(12 + 3x)x = 12x + 3x²

15x

12x + 3x = 15x

They all equal 15x except for (12 + 3x)x

Answer:

elevator 1 ends at floor 23. Elevator 2 ends at floor 42.

Step-by-step explanation:

x+10y

3x+2y+(-2x)+8y

First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + & - equals to -(minus) :-

3x-2x+2y+8y= x+10y

I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.

Answer:

Yes the number 42 is at its simplest form.

Step-by-step explanation:

Any whole number is already at its simplest form.

Answer:

Answer:

IJ = 20

Step-by-step explanation:

Point I is on the lines segment HJ. So,

HJ = HI + IJ

Putting all the given values, we get :

4x=2x+4x-10

Taking like terms together, we get :

-2x=-10

x=5

Put the value of x in IJ = 4x-10

IJ = 4(5)-10

IJ = 20

Hence, the value of IJ is 20.

(-4) - 6

-4 - 6

-10

I hope this is what you are looking for.

Answer:

The answer to this question is -10 because when you put -4-6 you get -10 and so the answer is -10!

Step-by-step explanation:

We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:

5x = 3x + 32

2x = 32 x = 16

ST = 5x = 80

So TU = 80

and SU=160
