Answer:

x=−1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(2−3x)=3(3+x)+4

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

4+−6x=9+3x+4

−6x+4=(3x)+(9+4)(Combine Like Terms)

−6x+4=3x+13

Step 2: Subtract 3x from both sides.

−6x+4−3x=3x+13−3x

−9x+4=13

Step 3: Subtract 4 from both sides.

−9x+4−4=13−4

−9x=9

Step 4: Divide both sides by -9.

−9x /−9 = 9 /−9

x=−1

A shark weighs 405 kg and 68 grams a second shark weighs 324 kg and 75 g how much more does the first shark weigh in grams than

mariarad [96]

For this case we have to by definition:

1 kg equals 1000 grams

Shark 1:

405 kg and 68 grams

$405 kg * \frac {1000 g} {1kg} = 405,000 grams$

Thus, shark 1 weighs 405,068 grams.

Shark 2:

324 kg and 75 grams

$324 kg * \frac {1000 g} {1 kg} = 324,000 grams$

Thus, shark 2 weighs 324,075 grams.

Subtracting we have:

$405.068 grams-324.075 grams = 80.993 grams$

Thus, shark 1 weighs 80,993 grams more than the second.

Answer:

Shark 1 weighs 80,993 grams more than the second.

Prove that in any triangle the length of a side is less than the half of the perimeter in statement reason format.

horrorfan [7]

Answer:

Proved

Step-by-step explanation:

I am going to pose c as the largest side in a random triangle

If so then remember that, by the triangle inequality, a + b > c. Let's start from there...

Statement: | Reasoning:

1. a + b > c 1. Triangle Inequality

2. a + b + c > c + c (adding c on both sides), 2. Algebra + Def. Of Perimeter

a + b + c > 2c (simplified)

Perimeter > 2c (definition of perimeter)

c < 1/2 * Perimeter

1. Four times a number minus twenty-one is the same as six times

Ganezh [65]

Answer: -16

Step-by-step explanation:

Let the number be y

Four times a number minus twenty-one can be written as:

(4 × y) - 21 = 4y - 21

Six times the number plus eleven can be written as:

(6 × y) + 11 = 6y + 11

Combining both equations will give:

4y - 21 = 6y + 11

4y - 6y = 11 + 21

-2y = 32

y = 32/-2

y = -16

The number is -16
