Answer:

y= 3x+4

Step-by-step explanation:

2y-6x=8

add 6x to each side

2y-6x+6x=6x+8

2y= 6x+8

divide each side by 2

2y/2 = 6x/2 + 8/2

y= 3x+4

Answer:

y = 3x+4

Step-by-step explanation:

2y-6x=8

We want to solve for y

Add 6x to each side

2y-6x+6x=6x+8

2y = 6x+8

Divide each side by 2

2y/2 = 6x/2 +8/2

y = 3x+4

Hope this answer helps you :)

Answer:

You can use 0.60 × 90, 3 × 18 works as well.

Step-by-step explanation:

Hmmm....let's see.

You can use 0.60 × 90, 3 × 18 works as well. The answer is 54.

We know this because when finding a percentage of a number you multiply that decimal by the number. 2nd option as well as last option could work. Hope this helps, please mark brainliest!

Answer:

C =(x-3)(x-2)/x

or

x²-5x+6/x

Step-by-step explanation:

2x^2 - 4x - 6/x + 2 * x^2 - 4/2x^2 + 2x

Factorizing the given factors

1) 2x^2 - 4x - 6

= 2x^2 - 6x+2x - 6

= 2x(x-3) +2(x-3)

= (x-3)(2x+2)

2) x^2 - 4

= (x+2) (x-2)

3) 2x^2 + 2x

= 2x( x+1)

Putting the factors

(x-3)(2x+2)/x + 2   *  (x+2) (x-2)/2x( x+1)

= (x-3)(2x+2) (x-2)/2x( x+1)

= 2(x-3)(x+1) (x-2)/2x( x+1)

=(x-3)(x-2)/x

Now multiply

(x-3)(x-2) =x²-5x+6

Then the answer becomes  x²-5x+6/x

Answer:

2012 km squared

Step-by-step explanation:

2600(.95)^5

if its going down by 5 percent, we minus 5 from 100 and put it in decimal form. any decimal lower than 1.00 will result in a lower number. for 5 years, we place 5 as an exponent

uh sorry if that doesn't make a lot of sense

Answer:

61 mph

Step-by-step explanation:

He drove 732 miles in 12 hours. How many miles would he drive if it was 1 hour? (per hour) If we subtract 732 by 12, the answer would be miles per hour. 732/12=61 Therefor, his speed is 61 miles per hour.

Answer:

C. y=3x^2-3

Step-by-step explanation:

y=3x^2-3 is lower than y=2x^2-1

So C.y=3x^2-3

The answer would be : C. -3x^2-3.

Hope this helps !

Answer:

Rectangular prisms are six-sided polygons; three-dimensional shapes of which all sides meet at 90-degree angles, like a box. Cubes are a special type of rectangular prism of which all sides are the same length; this is the key difference between cubes and other rectangular prisms.

Answer:

  A) r = d/t

  B) 221,760 ft/h

  C) 42 mi/h

  D) miles; the number is more comprehensible

Step-by-step explanation:

A) Given d = rt

Divide by the coefficient of r to solve for r.

  r = d/t

__

B) Fill in the given numbers to find the rate in ft/h.

  r = (665,280 ft)/(3 h) = 221.760 ft/h

__

C) Multiply by the conversion factor (1 mi)/(5280 ft) to convert to miles.

  (221,760 ft/h)(1 mi)/(5280 ft) = 42 mi/h

__

D) For this scenario, miles per hour is a better unit for speed. Many people have seen that speed registered on a speedometer, so have some sense of what it means. Often numbers outside the range of 1 to 1000 are beyond ready comprehension.

Answer:28/89

Step-by-step explanation: dont worry about this :/

Answer:

option on c or under the first answer

C option number line models the expression -1 1/4 - (-1/2)

A number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.

According to question the given expression is  -1 1/4 - (-1/2)

On solving  -1 1/4 = -5/4 or -1.25

and we can write (-1/2) as -0.5

so the expression is simplified to -1.25 - (-0.5) = -0.75

Thus the correct option is "C"

Answer:

x = 5.25

Step-by-step explanation:

Solve by substitution by substituting 2x as y into the first equation:

1/2(2x + y) = 21/2

1/2(2x + 2x) = 21/2

Simplify and solve for x:

1/2(4x) = 21/2

2x = 21/2

x = 21/4

x = 5.25

So, x = 5.25

Answer:

x = 5.25

step- by - step explanation

1/2 × ( 2x + y ) = 21/2 .............( 1 )

y = 2x ......................( 2 )

substitute the value of y in ( 1 )

1/2 ( 2x + 2 x ) = 21/2

simplify

1/2 ( 2 x + 2 x ) = 21/2

combine like terms

1/2 ( 4x ) = 22/2

Divide the numbers

1/2 ( 4 x ) = 10.5

divide 4 x by 2

4 x / 2 = 10.5

2 x = 10.5

divide each side by 2

2x/2 = 10.5 / 2

x = 5.25

Answer and Step-by-step explanation:

Answer:

56 cm^2

Step-by-step explanation:

Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.

Area of square base (side^2)

4^2 = 16 cm^2

Area of ONE triangular face (1/2 x b x h):

1/2 x 4 x 5 = 10 cm^2

Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2

ADD all the areas of triangles and square:

16 cm^2 + 40 cm^2 = 56 cm^2

Second, find the "middlest" of them . If there were total of odd numbers it would have been easier but, here is total of even number(4) and mean of 2 middlest number would be its median: (4+4)/2=4 .

Answer:

1st option

Step-by-step explanation:

Solving the inequality

5.25 - b ≥ 6.5 ( subtract 5.25 from both sides )

- b ≥ 1.25

Divide both sides by - 1, reversing the symbol as a result of dividing by a negative quantity.

b ≤ - 1.25

Since less than or equal to the number line will have a solid circle at - 1.25 and the arrow pointing left.
