Answer:

x = -5

Step-by-step explanation:

8x - 10 = 4x - 30

Subtract 4x from each side

8x-4x - 10 = 4x-4x - 30

4x -10 = -30

Add 10 to each side

4x-10+10 = -30+10

4x= -20

Divide by 4

4x/4 = -20/4

x = -5

Answer:

1. m∠1 = 45°

2. m∠1 = 129°

3. m∠1 = 37°

4. m∠1 = 88°

m∠2 = 42°

m∠3 = 113°

5. m∠1 = 62°

m∠2 = 45°

m∠3 = 24°

6. m∠1 = 128°

m∠2 = 52°

m∠3 = 47°

m∠4 = 133°

7. m∠1 = 41°

m∠2 = 85°

m∠3 = 95°

m∠4 = 85°

m∠5 = 36°

m∠6 = 50°

m∠7 = 107°

8. x = 9°

10. x = 5°

11. x = 7°

Step-by-step explanation:

1. m∠1 = 180° - (76° + 59°)  = 45°

m∠1 = 45°

2. m∠1 = 62° + 67°  = 129°

m∠1 = 129°

3. m∠1 = 152° - 115° = 37°

m∠1  = 37°

4. m∠2 = 42° (Alternate angles)

m∠1 = 180° - (50° + m∠2) = 180° - (50° + 42°) = 88°

m∠1 = 88°

m∠3 = 180° - (25° + 42°) = 113°

m∠3 = 113°

5. m∠3 = 73° - 49° = 24°

m∠3 = 24°

m∠2 = 118° - 73° = 45°

m∠2 = 45°

m∠1 = 180° - (73° + 45°) = 62°

m∠1 = 62°

6. m∠2 = 52° (Alternate interior angles)

m∠1 = 180° - 52° = 128° (The sum of angles on a straight line)

m∠1 = 128°

m∠3 = 47° (Alternate interior angles)

m∠4 = 180° - 47° = 133° (The sum of angles on a straight line)

m∠4 = 133°

7. m∠3 = 95° (Vertically opposite angles)

m∠2 = m∠4  (Vertically opposite angles)

m∠3 + 95° + m∠2 + m∠4 = 360° (The sum of angles at a point)

2 × 95° + 2 × m∠2 = 360°

m∠2 = (360° - 2 × 95°)/2 = 85°

m∠2 = 85° = m∠4

m∠2 = 85°

m∠4 = 85°

m∠1 = 360° - (85° + 140° + 90°) = 41°

m∠1 = 41°

m∠5 = 180° - 144° = 36°

m∠5 = 36°

m∠6 = 180° - (m∠5 + m∠3) = 180° - (36 + 95°) = 50°

m∠6 = 50°

m∠7 = 360° - (m∠4 - 38° - (180° - m∠6)) = 360° - (85° - 38° - (180° - 50°)) = 107°

m∠7 = 107° (Sum of angles in a quadrilateral)

8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 180°

Using an online application, we have;

(6·x - 12)° = 180°

x = (180 + 12)°/6 = 32°

x = 32°

9. (3·x - 5)° + (7·x + 5)° + 90° = 180°

Using an online application, we have;

10·x = 180° - 90° = 90°

x = 90°/10 = 9°

x = 9°

10. 151° = (11·x - 1)° + (20·x - 3)°

151° = 31·x - 4°

31·x = 151° + 4° = 155°

x = 155°/31 = 5°

x = 5°

11. (14·x - 13)° = (4·x + 13)° + (6·x + 2)°

(14·x - 13)° = (10·x + 15)°

(14·x - 10·x)° = (13 + 15)° = 28°

4·x = 28°

x = 28°/4 = 7°

x = 7°

1. 45°

2. 51°

3. 37°

4. 88°, 42°, 113°

5. 62°, 45°, 24°

6. 128 degrees, 52°,, 47°, 43° 83°

Answer:

20 + 0.05x ≥ 65

Step-by-step explanation:

20 is by itself since thats what he earns extra per day.

Since he earns 0.05 per flyer, that means we are going to need a variable since we don't know how many flyers he passes. Let x be equal to that.

Since he wants to make at LEAST 65 we are going to use the greater than or equal to symbol since he doesn't want to make less than that.

20 + 0.05x ≥ 65

Best of Luck!

Step-by-step explanation:

F=ma

a=F/m

a=800/200

a=4 m/s^2

Step-by-step explanation:

the answer

Answer:

[tex]\angle A=113\textdegree[/tex]

Step-by-step explanation:

We know that ∠A and ∠B are vertical angles.

Remember that vertical angles have the same measure. So:

[tex]\angle A=\angle B[/tex]

Substitute them for their equations:

[tex]7x-20=6x-1[/tex]

Solve for x. Add 20 to both sides:

[tex]7x=6x+19[/tex]

Subtract 6x from both sides. So, the value of x is:

[tex]x=19[/tex]

To find ∠A, we can use its equation again:

[tex]\angle A=7x-20[/tex]

Substitute 19 for 7:

[tex]\angle A=7(19)-20[/tex]

Multiply and subtract:

[tex]\angle A=133-20=113\textdegree[/tex]

So, the value of ∠A is 113°.

And we're done!

Answer:

[tex]y=-\frac{2}{3}x+2[/tex]

Answer:

5x5=25

Step-by-step explanation:

5 x 5

= 5(1 + 0) x 5(1 + 0)

=5(1 + 1 - 1) x 5(1 + 1 - 1)

=5(2 - 1) x 5(2 - 1)

=(10 - 5) x (10 - 5)

=5 x 5 :0

=> 5 x 5 = 5 x 5 = 25

Answer:

[tex]f^{24}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] , thus

[tex]f^{12}[/tex] × [tex]f^{12}[/tex] = [tex]f^{(12+12)}[/tex] = [tex]f^{24}[/tex]

Answer:

Step-by-step explanation:

1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]

= 11

2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]

= 1

3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]

= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]

= 5

4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]

= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]

= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]

= 1

5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]

= 5

6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}\times \frac{7}{2}[/tex]

= 11

Now we can classify the expressions by their quotients as 1, 5 and 11.

Answer:

$5,415.49

Step-by-step explanation:

Cost of the boat = $16,500

Decrease in value per year = 13%

Worth of the boat in 8 years = ?

Remaining value = 100% - 13%

= 87%

Worth of the boat in 8 years = cost of the boat × remaining value^8

= $16,500 × 87%^8

= $16,500 × 87/100^8

= $16,500 × 0.87^8

= $16,500 × 0.3282116715437121

= $5,415.49

The worth of the boat after 8 years = $5,415.49

Answer:

1=51 3=51

Step-by-step explanation:

So we know since the line are parlle that the angles for each would be idetical

so 6,8,2, and 4 would all have same angle of 129

to find the other angles we would subtract 180 (the degree of a stright line) from 129 getting 51

so now we know that angles 1,3,5 and 7 are 51 degrees

Answer:

The runner's unit rate is:  7 mph

Step-by-step explanation:

The runner's unit rate is the speed of the runner used to cover a mile in one hour

Given that ;

1/4 hours covers 7/4 miles

so;

1/4 = 7/4

1 =?

Perform cross product as;

(1*7/4) / 1/4

(7/4) / (1/4)

7/4 * 4/1

7 miles/hour

Answer:

Step-by-step explanation:

odd functions are those function in which  

-f(x) = f(−x)  

if the function is odd , the graph of function is symmetrical about origin.

_________________________________________________

In the given problem

option B is correct answer

B) f(x) = 8x

replacing x with -x to satisfy the above described condition

f(-x) = 8(-x) = -8x

as we know 8x is equal to f(x)

f(-x) = -8x = -f(x)

hence,

f(-x) = -f(x)

hence, option B is correct answer.
