Answer:

so easy just divide then mulitply by two

Step-by-step explanation:

Answer:

3. 17x + 5 = 90° ( alternate exterior angles are equal)

=> 17x + = 90 – 5

=> 17x = 85

=> x = 85/17

=> x = 5

4. 63° + c + 110° + 75° + 50° = 360 °

=> c + 298° = 360°

=> c = 360° – 298°

=> c = 62 °

Answer: 29

Step-by-step explanation:

The answer is 29 because 29 - 16 = 13

Answer:

9x^4+21x^3+13x^2-x-2

Step-by-step explanation:

just foil (3x-1)(x+1)=3x^2+3x-x-1=f oil your answer (3x^+2x-1)with (X+1) this gives you 3x^3+3x^2+2x^2+2x-x+1 reduces to 3x^3 +5x^2+x+1 foil that with 3x=2

which gives you you answer

Answer:

No

Step-by-step explanation:

Let's plug x = 5

(20 - 2) - 2(15 + 3) = 9 + 2(5 + 4)

Simplify -->

18 - 30 + 6 = 9 + 10 + 8

--> -12 + 6 = -6 --> 19 + 8 = 27

-6 is not equal to 27

thus, it is false

Answer:

20 boys

Step-by-step explanation:

Variables: g = girls; b = boys

Step 1: set up basic equation

60 = g + b

Step 2: define variable

g = 2b

Step 3: replace variable in the equation

60 = 2b + b

Step 4: solve

60 = 3b

60/3 = b

20 = b

Answer:

The Answer Is 30

Step-by-step explanation:

There were 60 boys and girls and twice as many girls were there, 30 x 2 = 60 :0

Answer:

2n ÷ 9 - x

Step-by-step explanation:

The product of 2 and a number, I used "n" to replace the number. Putting a number next to a variable means multiplying.

So we have 2n and divide by the difference (subtracting) of 9 and ANOTHER number, that means we need a different variable for this I used "x".

And that's how I got 2n ÷ 9 - x as my answer.

Hope that helps and have a great day!

Answer:

x= -5

Step-by-step explanation:

Replace f(x) with 3, because f(x) is a fancy way of saying y. The equation is 3=-x-2. Add 2 to both sides to isolate the variable. You get 5=-x. Divide -1 from both sides to further isolate the variable. You get -5=x.

Answer:

24

Step-by-step explanation:

subract 4 each time

As per arithmetic progression, the number comes after 28 in the given series is 24.

"An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. "

The first term is = 40.

The common difference is (d) = 36 - 40 = 32 - 36 = 32 - 28 = - 4.

Here, the given series is in arithmetic progression.

Therefore, the next term after 28 is

= 28 - 4

= 24

Answer:

0.42 it is terminating because it goes 66666 but then changes to a 7 at the end

Step-by-step explanation:

5/12 is just like a division problem. You divide 5 by 12 to get 0.416666667 which is the full answer and you take the first two numbers after the decimal to be your answer. But if there is a 5 or higher after the second number you can round it to its nearest tenth.

Answer:

The least common denominator is 21.

Step-by-step explanation:

First, you must find the least common factor of the two:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Second, you must increase the fractions:

[tex]\frac{1}{3}[/tex] × [tex]\frac{7}{7}[/tex] = [tex]\frac{7}{21}[/tex]           [tex]\frac{3}{7}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{9}{21}[/tex]
