Answer:

The answer is 68 degrees.

Step-by-step explanation:

Angles of a triangle add up to 180 degrees. So you have to subtract 75 and 37 from 180. (180 - 75 - 37 = 68)

Answer:

C. 68°

Step-by-step explanation:

The angles in a triangle should all add up to 180°, so...

75°+37°+x°=180°

112°+x°=180°

x°=68°

Answer:

80°

Step-by-step explanation:

Angle CBD = 100°

Angle ABC = 180° - 100° = 80°

Angles on a straight line add up to 180°.

Angle ABC and angle EFB are corresponding angles, so they are equal.

Answer:

Percent = 70%

fraction = 7/10

Step-by-step explanation:

Percent

14 / 20 = 0.7

0.7 x 100 = 70%

Fraction

14 / 20

7 / 10

(just simplify 14/10 by dividing by 2 on the numerator and demotinator.)

14 out of 20 can be written as the fraction 7/10 and as the percentage 70%.

To write 14 out of 20 as a fraction, we can simply write it as a ratio of 14 to 20.

Fraction: 14/20

However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2.

Dividing 14 by 2, we get 7, and dividing 20 by 2, we get 10.

So, the simplified fraction is:

7/10

To express this fraction as a percentage, we can convert it by multiplying it by 100.

Percentage: (7/10) x 100 = 70%

Therefore, 14 out of 20 can be written as the fraction 7/10 and as the percentage 70%.

Step-by-step explanation:

F(5) is just saying that the function of x is equal to 5

Answer:

x=3

Step-by-step explanation:

12x-14=4x+10​

Subtract 4x from each side

12x-4x-14=4x-4x+10​

8x - 14 = 10

Add 14 to each side

8x - 14+14 = 10+14

8x = 24

Divide each side by 8

8x/8 = 24/8

x = 3

Answer: x = 3

Explanation: This problem can be done either of two ways.

By putting the variables together on the left and

the numbers together on the right or vice versa.

If we put our variables together on the left and our

numbers together on the right, we would start by

subtracting 4x from both sides to get 8x - 14 = 10.

Next, we add 14 to both sides to get 8x = 24.

Finally, we divide both sides by 3 to get x = 3.

Answer:

[tex]4\sqrt{7}[/tex]

Step-by-step explanation:

Its a 45, 45, 90 triangle, which means that the hypotenuse is always the equals sides length by [tex]\sqrt{2}[/tex].

[tex](2\sqrt{14} )*\sqrt{2} = 4\sqrt{7}[/tex]

Answer:

[tex]4\sqrt{7}[/tex]

Step-by-step explanation:

The lines on the two sides of the triangle represent congruency (meaning that they both are worth the same value)

Use pythagorean theorem [tex]a^{2} + b^{2} = c^{2}[/tex]. a and b are both the same value

Square root to find c

The answer is then [tex]\sqrt{112}[/tex]  now we need to simplify it further into radical form

Find the greatest set of numbers that include one perfect square and the other a normal number. These numbers should multiply to be 112

These numbers are 16 and 7

16 is the perfect square number because when you square root it, it is a clean number... 4!

The perfect square root always goes outside the radical and the other number (which is 7 in this case) always goes inside the radical

Answer:

$70

Step-by-step explanation:

To add a tip, we must multiply the cost of the bill by 1.15. This will give us the total amount including the tip.

57.86 x 1.15 = 66.539

Because this is money, and it wants us to round to the nearest ten dollars, the cost would be $70. (66.539 is closer to 70 than it is to 60)

Answer:

1  2/3

Step-by-step explanation:

The denominators are the same, so we have to borrow from the 4

Borrow  1 in the form 6/6

3 + 6/6+3/6  - 2 5/6

3 9/6   - 2 5/6

1 4/6

Simplify the fraction by dividing the top and bottom by 2

1  2/3

Step-by-step explanation: To subtract mixed numbers, first subtract the fractions.

Notice here however that we have 3/6 - 5/6

which will give us a negative fraction.

Since this will cause us a lot of trouble, instead,

let's rewrite the first mixed number.

We can do this by thinking of 4 and 3/6 as 3 + 1 and 3/6

or 3 + 9/6 by changing 1 and 3/6 to an improper fraction.

So 4 and 3/6 can be written as 3 and 9/6.

So we have 3 and 9/6 - 2 and 5/6.

Now subtract the fractions.

9/6 - 5/6 is 4/6.

So we have 1 and 4/6 or 1 and 2/3.

As an improper fraction, the answer is 5/3.

Answer: The product of 85 and 25 is 2125 .

85x25 = 2125

Step-by-step explanation:

Answer:

  (a)  (a² +3a -1)(a² -3a -1)

Step-by-step explanation:

The constant term of the product of the factors will be equal to the product of their constants. Since you want that product to be +1, the signs of the factor constants must be the same. That eliminates choices (c) and (d).

__

To tell which of choices (a) and (b) is correct, we can compute the squared term in their product. Let's do it in a generic way, with the constant (±1) being represented by "c".

We want the a² term in the product ...

  (a² +3a +c)(a² -3a +c)

That term will be the result of multiplying both sets of first and last terms, and adding the product of the middle terms:

  (a²·c) +(a²·c) -9a² = a²(2c-9)

So, we want the factor (2c-9) to be -11, which means c=-1, not +1.

The correct factorization of the given expression is ...

  (a² +3a -1)(a² -3a -1) . . . . matches choice A

$10 a month fixed plus $0.10 for each message.  

Variable:

m - number of text messages per month

Function:

c(m) - cost per month in dollars of Text-Pay Plan for m messages

Answer: c(m) = 0.10 m + 10

The Frequent text plan costs $20 for 0 messages (that's the fixed cost) and has a slope of (30 - 20)/200 = 1/20 = 0.05 dollars per message.

f(m) = 0.05 m + 20

How many text messages per month make these equal?

c(m) = f(m)

0.10 m + 10 =  0.05 m + 20

0.10 m - 0.05 m = 20 - 10

0.05 m = 10

m =  10/0.05 = 200

Check:

c(200) = .1(200)+10 = 20+10 = 30

f(200) = .05(200) + 20 = 10 + 20 = 30, good

4x -12 -2x +2 > 0

Combine like terms

2x -10 >0

Add 10 to each side

2x-10+10 > 10

2x>10

Divide each side by 2

2x/2 > 10/2

x >5

The answer is: [C]: " {x | x > 5} " .

__________________________________________

Explanation:

__________________________________________

Given: " 4(x − 3) − 2(x − 1) > 0 " ;

__________________________________________

Note the "distributive property of multiplication" :

__________________________________________

a(b+c) = ab + ac ;

a(b−c) = ab − ac ;

___________________________________________

So, given:

_________________________________________________

→ 4(x − 3) − 2(x − 1) > 0 ;

_________________________________________________

Let us simplify; and rewrite:

_________________________________________________

Start with:

______________________________________________________

→ -2 (x − 1) = (-2*x) − (-2 *1) = -2x − (-2) = -2x + 2 ;

______________________________________________________

Now, continue with:

→ 4(x − 3) = (4*x) − (4*3) = 4x − 12 ;

______________________________________________________

So, given the original problem:

______________________________________________________

→ 4(x − 3) − 2(x − 1) > 0 ;

______________________________________________________

Rewrite;

Replacing: "4(x − 3)" ; with: "4x − 12" ;

and replacing "− 2(x − 1)" ; with: " -2x + 2" ;

______________________________________________________

as follows: → " 4x − 12 − 2x + 2 " > 0 ;

______________________________________________________

On the "left-hand side", combine the "like terms", and simplify ;

______________________________________________________

+4x −2x = +2x ; −12 +2 = -10 ; and rewrite:

______________________________________________________

→ 2x − 10 > 0 ; Add "10" to EACH SIDE of the inequality;

______________________________________________________

→ 2x − 10 + 10 > 0 + 10 ;

______________________________________________________

to get: → 2x > 10 ;

______________________________________________________

→ Now, divide EACH SIDE of the inequality by "2";

to isolate "x" on one side of the inequality; & to "solve"/"simply" for "x" ;

_______________________________________________________

→ 2x / 2 > 10 / 2 ;

_______________________________________________________

→ x > 5 ; which is:

_______________________________________________________

→ Answer choice: [C]: " {x | x > 5} " .
