Answer:

a=3c+4b

Step-by-step explanation:

-8b + 2a = 6c

(-8b + 2a) + 8b = 6c + 8b

-8b + 2a + 8b = 6c + 8b

-8b + 8b + 2a = 6c + 8b

2a = 6c + 8b

2a/2 = 6c + 8b/2

a = (2x3)c + [tex]2^{3}[/tex] x b)/2

a = 3c + 4b

Answer:

  a, b, e (only)

Step-by-step explanation:

The circle centered at A is all of the points that are distance AB from A.

The circle centered at B is all of the points that are distance AB from B.

The points C and D are points that are distance AB from both A and B.

The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.

Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.

__

Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.

__

With some work using the Pythagorean theorem, you can show that ...

  CM = AM×√3

Similarly, MD = BM×√3.

Adding these two relations tells us ...

  CM +MD = √3(AM +BM)

  CD = AB×√3 . . . . . AB and CD are not the same length

__

AM and BM are on the same line, so cannot be perpendicular to each other.

When you are studying compass and straightedge constructions, you would do well to actually perform these constructions using those tools on paper. This gives you a feel for what is going on and helps you remember the steps. A computer screen is no substitute for hands-on.

Answer:

Probably B.

Step-by-step explanation:

It's a 50% chance and the other ones seem less likely than that.

A. no clue what that means

B. 1/2 chance/ 50%

C. 1/6 chance which is not as great as B.

D. 1/3 chance which is closer to B but still not as good.

Answer:

2 plain folders and 7 folders with cartoons

Step-by-step explanation:

Given data

Let the number of plain folders be x

and the number of folders with cartoons  be y

x+y=7------------1

x+2y=12----------2

from 1

x= 7-y

put this in 2

7-y+2y=12

7+y= 12

y= 12-7

y=5

Put y=5 in 1

x+5= 7

x= 7-5

x= 2

Hence Ayin bought 2 plain folders and 7 folders with cartoons

Answer:

y=7x+2

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

Answer:

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

2 + (1/10)(1/5)(1/10)2000 = 2 + (1/500)(2000) = 2 + 4 = 6

The number that is two more than one-tenth of one-fifth of one-tenth of 2,000​ will be 6.

The ratio is the division of two numbers while multiplication is an operation in mathematics to multiply two or more values to get a multiplied number.

Proportion is the relation of a variable with another. It could be direct or inverse.

The one-tenth of x = (1/10)x similarly

one-tenth of one-fifth of one-tenth = (1/10)(1/5)(1/10)

So  one-tenth of one-fifth of one-tenth of 2,000​ =  (1/10)(1/5)(1/10) ×2000

⇒ 2000/500 = 4 Now the question is saying 2 more hence

⇒ 4 + 2 = 6 hence six will be the correct answer.

Answer:

12x - 9y

Step-by-step explanation:

According to the distributive property:

3(4x - 3y) =

3*4x - 3*3y =

12x - 9y

Answer:

12x - 9y you can't subtract different variables so multiply by them both by the left over constant and get the expression of 12x - 9y

Step-by-step explanation:

5^6=15625

5^2=25

15625/25=625

Answer: $7.25

Step-by-step explanation:

Let T = taco cost

Let M = milk cost

T + M = 2.10

2T + 3M = 5.15

Multiply the first equation by (-2) and add it to the second equation

-2T - 2M = -4.20

2T + 3M = 5.15

M = 0.95

Plug this value for M in to the first equation

T + 0.95 = 2.10

T = 1.15

So a taco costs $1.15 and the milk costs $0.95

1.15 * 3 = 3.45

0.95 * 4 = 3.80

3.45 + 3.80 = 7.25
