Answer:

x =7

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( 2x − 3 ) = 6x + 2

Step 1: Simplify both sides of the equation.

4 ( 2x − 3 ) = 6x + 2

( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )

8x + −12 = 6x + 2

8x − 12 = 6x + 2

Step 2: Subtract 6x from both sides.

8x − 12 − 6x = 6x + 2 − 6x

2x − 12 = 2

Step 3: Add 12 to both sides.

2x − 12 + 12 = 2 + 12

2x = 14

Step 4: Divide both sides by 2.

2x  / 2  =  14  / 2

x = 7

Answer:

3.     P = 48 units   A = 116 units²

Step-by-step explanation:

A = 12 x 12

= 144

Now we can subtract the missing areas. 4 x 4 = 16 and 6 x 2 = 12.

144 - 16 - 12

= 116 units²

P = 12 + 12 + 12 + 12

= 48 units

Step-by-step explanation:

Combine like terms, add 8 to both sides of the equation, simplify, divide both sides by the same term, simplify

Answer:

x = 2

Step-by-step explanation:

1. Combine like terms

15x - 8 - 3x = 16

1 2  −  8  =  1 6

2. Add  8  to both sides of the equation

Answer:

The sum of a rational number and an irrational number is irrational

Step-by-step explanation:

By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.

Step-by-step explanation:

1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5

2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

Answer:

Prism A: 264; Prism B: 265.125

Step-by-step explanation:

✔️Surface area of the triangular prism = base area + Perimeter*Height of prism

Base area = ½*bh

b = 6 cm

h = 8 cm

Base area = ½*6*8 = 24 cm²

Perimeter of base = 6 + 8 + 10 = 24 cm

Height of prism = 10 cm

Surface area of the triangular prism = 24 + 24*10 = 264 cm²

✔️Surface area of rectangular prism = 2(LW + LH + HW)

L = 5.25 cm

W = 5.25 cm

H = 10 cm

Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)

= 265.125

Answer:

Equation: y = 8x + 56

After 5 minutes, the volume of the water was 96 gallons

Step-by-step explanation:

Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.

Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.

There are already 56 gallons of water in the tank, so b will be 56.

Plug in these values into the equation:

y = 8x + 56

So, the linear equation is y = 8x + 56

Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:

y = 8x + 56

y = 8(5) + 56

y = 40 + 56

y = 96

So, after 5 minutes, the volume of the water was 96 gallons

The first one I'll do is Physics because you know the amount of girls and total amount of students. Use the equation x+19=33. Note that x is the amount of boys we are trying to find. All you need to do is simply subtract 19 from both sides to get x alone.

                                             x + 19 = 33

                                                  -19   -19

                                             x         = 14

For the total that's going up and down, you can do this same process again, but just using x for girls instead of boys. Your equation should look like 47+x=80. Once again, subtract 47 from both sides.

                                             47 + x = 80

                                             -47        -47

                                             x         =  33

Now you can find whole row for boys. This equation will be a little longer, but it's still pretty easy. 18+x+14=47 is what we will be using. We first will need to combine like terms (the 18 and 14), then subtract it off from both sides to get x alone.

                                             18 + x + 14 = 47

                                                    x + 32 = 47

                                                        -32   -32

                                                     x         = 15

Moving onto the biology column, we'll be using the equation 15+x=21

                                             15 + x = 21

                                            -15        -15

                                             x         = 6

Now we can find out the girls column with this equation: x+6+19=33

                                           x + 6 + 19 = 33

                                           x + 25      = 33      

                                               -25         -25

                                                     x      = 8

Lastly, we can find the chemistry column by just adding 18+8 to get 26.
