A) -0.3=-30c

divide on both sides ⇒ [tex]\frac{-0.3}{-30} = \frac{-30c}{-30}[/tex]

0.01 = c

B) do the same way. a =-30

C)    14  -  b  =  14.2

      +14            +14

              -1b =  28.2

          -1b/-1  =  28.2/-1

b = -28.2

Answer:

 (dependent)

(Incosistent)

(Independentt)

Step-by-step explanation:

{4x−2y=102x−y=5  

{y=2x−3−2x+y=−5

{2x−5y=143x+4y=10

The system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

A) The given system of equations are 4x−2y=10 and 2x−y=5

4/2 = (-2)/(-1)=10/5

2=2=2

Since, a₁/a₂ =b₁/b₂=c₁/c₂

The system of equations have infinitely many solution, so they are consistent dependent.

B) y=2x-3 and -2x+y=-5

Here, 2x-y-3=0 and -2x+y+5=0

2/(-2)=(-1)/1≠(-3)/5

-1=-1≠(-3)/5

Since, a₁/a₂ =b₁/b₂≠c₁/c₂

The system of equations are parallel, so they are inconsistent equations.

C) 2x−5y=14 and 3x+4y=10

Here, 2x-5y-14=0 and 3x+4y-10=0

2/3≠(-5)/4≠(-14)/(-10)

Since, a₁/a₂ ≠b₁/b₂

The system of equations have unique solution, so they are consistent independent.

Therefore, the system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.

Answer:

C

Step-by-step explanation:  

Answer:

a. standard notation means in the number written in only number digits.

- to convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.

remember: if the exponent is negative, you have move the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.

3 X 10^-4 --> move 4 places to the right.

answer - table salt: 0.0003

1.2 X 10^-2 --> move 2 places to the right.

answer - rock salt: 0.012

b. we know the standard notation of table salt is 0.003, so we simply multiply 40 by this.

answer - 0.0003 X 40 = 0.012

c. 0.012 = 0.012 (yes)

answer - yes the value i got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.

- i am not sure about the "what does this mean" part. you can put whatever there but i put what i think it could be. i think it would be based on what notes you took on class.

Part(a),

The value of the masses in standard form is Rock salt: 0.012 and Table salt: 0.0003.

Part(b),

The multiplication is 0.012.

Part(c),

yielded a value equal to the mass of an average grain of rock salt. This demonstrates that the mass of an average grain of rock salt is 1/40 that of an average grain of table salt.

Answer:

  80% decrease

Step-by-step explanation:

The percentage change is found from ...

  percent change = ((new value)/(old value) -1) × 100%

  = (230/1150 -1) × 100%

  = -0.8 × 100%

  = -80% . . . . . a negative change is a decrease

The store's flour quantity decreased by 80%.

Answer:

Carlos scored about 28% of his team points.

Answer:

5/36

Step-by-step explanation:

Basally you just need to see how many of the dices added up to 6. (6 and 1 don't count because that would add up to 7.)

Then find how many possibilities there were, in this case 36. 5 out of 36.

In other cases you would simplify if need be.

Answer:

-6

Step-by-step explanation:

Manipulating the initial inequality, we get x < -4

Out of the given ones, only -6 is STRICTLY smaller than -4, thus the only one that satisfies the inequality.

Answer:

2:3

4:6

6:9

18:27

Step-by-step explanation:

The constant of proportionality is 2:3 for this problem. On the second one, I saw that there was a 6. 6 was double what 3 is so I multiplied 2 by 2 and got 4. I basically did that with the rest of the problems. like the second one there is a 6 on the left side, 6 is 3 times the amount of two so I multiplied 3 by 3 to get 9. On the last one, there was a 27 on the right side. 27 is 9 times greater than 3 so I multiplied 2 by 9 to get 18 on the left side. I hope I didn't make it too confusing.

Have a good day!

Step-by-step explanation:

bc the first number represent x and the second y

(x,y)

Answer:

answer is 1

Step-by-step explanation:

the x coordinate, -1.5, is negative so you must go to the left 1.5 on the x axis. then y is also negative at, -1, so you must go from the -1.5 on the x axis down one to -1

Answer:

Ok so u know to divide bc u r trying to isolate the variable and that means undoing the function in this case 0.6 is multiplied to p so u do the opposite which is division

tada

Hope this helps :)

Pls give brainliest XD :)

Answer: You're looking for what P represents

Step-by-step explanation:

You start off with the equation

then subtract the number without the variable in this case both sides. Leaving 4.5-4.5= 0 and 22.5-4.5= 18

You also need to have p as P=n  (n= the number)

The equation 18/.6- 30, however you are looking for

0.6 divided by 18 which equal 0.33

so p=0.33
