Step-by-step explanation:

times -4 by everything inside the bracket

-4 times 5x = -20x

-4 times +3 = -12

-4(5x+3) = -20x - 12

(a positive times a negative is a negative)

Answer:

Step-by-step explanation:

∠A and ∠B are vertical => ∠A=∠B

20x+10=30x-10

20x-30x= -10-10

-10x= -20

x= -20 / -10 = 20 / 10 = 2

x=2

Good luck!

Answer:

2

Step-by-step explanation:

Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.

If angle a and b are vertical angles what does that mean?

they are CONGRUENT!

you know A = 20x+ 10 and B= 30x-10

so you can write it as

20x+10 = 30x-10

because Angle A and B equal each other

then get the variable by itself so subtract -20x on both sides

10 = 10x-10

then add 10 to both sides which is

20 = 10x

and divide 10 on both side and 20 divided by 10 is 2

so 2 =x

which is the same as x =2  

A decimal number with a digit or group of digits that repeats forever is called a repeating decimal.

Answer: 5489

Step-by-step explanation:

Given the following :

Growth rate (r) = 19% per hour

Sample culture in population = 2300

Size of sample after 5 hours =?

Using the exponential relation:

P = Po * r^t

P = population after 5 hours

Po = Initial sample population

t = time

P = 2300 * (1 +19%)^t

P = 2300 ×(1 + 0.19) ^5

P = 2300 * 1.19^5

P = 2300 * 2.3863536599

P = 5488.61341777

P = 5489 (nearest integer)

This is an example of a two-column algebraic proof using 4x + 9 = 16 - 3x

Step-by-step explanation:

Answer:

x + 4 ⩽ 15

Step-by-step explanation:

Let

The number = x

At least in inequality is ⩾ (greater than or equal to sign)

At most in inequality is ⩽ ( less than or equal to sign)

A number increased by 4 is at most 15.

x + 4 ⩽ 15

The inequality that represent the statement is x + 4 ⩽ 15

x + 4 ⩽ 15

x ⩽ 15 - 4

x ⩽ 11

Answer: 24 is the least number of gloves and baseball need to purchase .

Step-by-step explanation:

Given:  Gloves are sold in cases of 8 and baseballs are sold in cases of 12.

To get the  exact same number of gloves as baseballs, the least number of gloves and baseball need to purchase = L.C. M. (8,12)

[L.C.M.= Least common multiple]

Since 8 = 2 x 2 x2

12 = 2 x 2 x 3

So,  L.C. M. (8,12) = 2 x 2 x 2x 3 = 24

Hence, the least number of gloves and baseball need to purchase = 24

==========================================

Work Shown:

A = 50 = number of words typed in 1 minute

B = 1 minute

C = 500 words

D = x minutes (needed to type 500 words)

A/B = C/D

50/1 = 500/x

50*x = 1*500 ... cross multiply

50x = 500

x = 500/50 .... divide both sides by 50

x = 10

You'll need 10 minutes to type 500 words

------------

Alternative approach:

50 words = 1 minute .... given speed

1 word = 1/50 minute ... divide both sides by 50

1 word = 0.02 minute

500 words = 10 minutes .... multiply both sides by 500

As per the given data, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

If you have a typing speed of 50 words per minute, it means you can accurately type 50 words in one minute. This rate is often considered an average typing speed for proficient typists.

If I can type 50 words per minute, then to determine the number of minutes it would take to type a 500-word essay, we can divide the total number of words by the typing speed:

Time (in minutes) = Total words / Typing speed

Time = 500 words / 50 words per minute

Time = 10 minutes

Therefore, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

Answer:

Step-by-step explanation:

Given the expression [tex]\frac{1}{2} - 1\frac{1}{5}[/tex], we are to find the difference

First convert the mixed fraction [tex]1\frac{1}{5}[/tex] to improper fraction

[tex]1\frac{1}{5}[/tex] = [tex]\frac{6}{5}[/tex]

The expression becomes;

Step-by-step explanation: 8 can go into 24 perfectly but not 15 and 5 can go into 15 perfectly but not 24 but 24/3 is 8 and 15/3 is 5

You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3

Answer:

3

basically,  8 can go into 24 exactly but 15 and 5 can not go into 15 perfectly neither can 24.  24/3 is 8 and 15/3 is 5

Answer:

y= -1.5x-7

Step-by-step explanation:

y= -16 (total amount of meters below ground)

m= -1.5 (slope; meters he descends per minute)

x= 6 (minutes)

b= -7 (starting point)

thus; y= -1.5x-7

because; -16=(-1.5)(6)-7

note; remember, they are descending so most of your values will be negative

Answer:

- 72x-1 /8x

Step-by-step explanation:

Answer: -15+1/8x

Step-by-step explanation:

-9+1/4x-6-1/8x

You must add the 9 and 6 because they are both negative numbers and you get -15. You would multiply 1/4 by two in order to subtract 1/4 from 1/8. You would have 2/8-1/8 which would get you 1/8.
