Answer:

x = - 2

Step-by-step explanation:

Given

6 - 4x = 7x - 9x + 10, that is

6 - 4x = - 2x + 10 ( add 2x to both sides )

6 - 2x = 10 ( subtract 6 from both sides )

- 2x = 4 ( divide both sides by - 2 )

x = - 2

Answer: x = -2

Step-by-step explanation:

Answer:

The conclusion of the conditional statement is;

it is an integer and a prime number

Step-by-step explanation:

The statement that the argument claims to be true or the statement that the rest of a conditional statement leads to is the conclusion of a conditional statement

Given a conditional statement, also known as an if-then statement, which can be represented symbolically as p → q, such that the hypothesis is p and the conclusion is q.

In the given statement, the hypothesis, p = a number is odd, while the conclusion, q =  it is an integer and a prime number

Therefore, the conclusion of the conditional statement is it is an integer and a prime number.

However, only the converse of the statement is true, which is given as follows;

If a number is an integer and a prime number, then it is an odd number

Answer:

x = - 2

Step-by-step explanation:

Given

- x - 4 + 3x = - 5x - 18 , that is

2x - 4 = - 5x - 18 ( add 5x to both sides )

7x - 4 = - 18 ( add 4 to both sides )

7x = - 14 ( divide both sides by 7 )

x = - 2

The given lines n: y = -2x-4 and line m: y = -2x+8 are neither parallel nor perpendicular

The slope of the parallel line is 0 and the slope of the perpendicular line is undefined.

The lines are parallel if their slopes are the same but their y-intercepts differ. The lines are not parallel if the slopes differ. Perpendicular lines, unlike parallel lines, do intersect. Their intersection creates a 90-degree angle.

Here given line ,

y = -2x - 4

= y = 2x + 4

Since this is in mx + b form ,

m is the slope

So slope = 2.

Given another line = -2x + 8

Slope = -2

Since slopes are not equal they are not parallel .

Since slopes are not negative reciprocal they are not perpendicular .

Answer:

360

Step-by-step explanation:

If you multiply 20 by 6 you get 120

then if you multiply 1.50 by 8 you get 12

then multiply 12 by 20 which equals 240

add 240 by 120 you get your final answer 360

x + 21 + 3x + 9 = 90

Combine like terms

4x + 30 = 90

Subtract 30 from both sides

4x = 60

Divide both sides by 4

x = 15

Answer:

x = 15

Step-by-step explanation:

You can use the opposite angles property to solve this problem. By using the property, the opposite angle of x+21 must also be x+21. So therefore, you can setup the equation x+21+3x+9=90. Simplify and you should get 4x+30=90. Subtract 30 on both sides and you get 4x=60. Divide 4 on both sides and you get x=15.

Answer:

b = A / h

Step-by-step explanation:

A = b * h

Dividing the equation by h to get b on one side give us:

A / h = b * h / h

A / h = b * 1

A / h = b

b = A / h

Answer: 210

Step-by-step explanation:

We know that the number of combinations of n things taken r at a time is given by :-

[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]

So, number of ways to select 3 plants out of 7 = [tex]C(7,3)=\dfrac{7!}{3!4!}=\dfrac{7\times6\times5\times4!}{6\times 4!}=7\times5=35[/tex]

Also number of ways to arrange them in 3 positions = 3! = 6

Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)

= 35 x 6

=210

Hence, required number of ways = 210

Since, the arrangement does not matter, we use the principle of combination, Hence, the number of display arrangement possible is 210

This could be defined thus as : (7C3) × 3! ;

3! = number of ways to arrange the 3 plants into the 3 spots

Recall :

7C3 = [tex] \frac{7!}{(7-3)!3!} = \frac{7!}{4!r3!} [/tex]

7C3 = [tex] \frac{7×6×5}{6} = 35 [/tex]

3! = 3 × 2 × 1 = 6

(7C3) × 3! = 35 × 6 = 210 ways

Therefore, there are 210 possible arrangements which can be made.

Answer:

B. 4 tablespoons

Step-by-step explanation:

Let’s make a proportion using the following setup:

tablespoons/servings=tablespoons/servings

We know that 12 tablespoons are needed for 60 servings.

12/60=tablespoons/servings

We don’t know how many tablespoons are needed for 20 servings. We can say x tablespoons make 20 servings.

12/60=x/20

Want want to solve for x, so we must isolate x. x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the proportion by 20.

20*(12/60)=(x/20)*20

20*12/60=x

20*0.2=x

4=x

x= 4 tablespoons

4 tablespoons of butter are used to make 20 servings.

Let x be the number:

Twice the difference of a number and 5 is 30:

2(x - 5) = 30

Divide both sides by 2:

x - 5 = 15

Add 5 to both sides:

x = 20
