Help me solve this pleasee

Answer:

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables.

Step-by-step explanation:

The parts of mathematics in which letters and other general systems are used to represent number and quantities in formulas and equations.

Step-by-step explanation:

11) x^5

12) 5x^2

13) x+21

14) 2x-8

15) 3^3

=3*3*3

=27

16)2^5

=2*2*2*2*2

=32

17) 5^4

=5*5*5*5

=625

18)2 times a number p squared

19)3 times a number m fifth power

20)the addition of half a number and 2

Answer:

False.

Step-by-step explanation:

.

17+1= 18

12= -6

12-17= -5 + 1 =-4.

Answer:

False

Step-by-step explanation:

12- (17 + 1) = (12 - 17) + 1

PEMDAS says parentheses first

12- (18) = (-5) + 1

Then add and subtract

-6 = -4

They are not equal

Answer:

33.4%= 33.4 ÷100×9000= 3006.0

Answer:

To sum up, 1683/20 = 84.15. The number has 2 decimal places. As division with remainder the result of 1683 ÷ 20 = 84 R 3.

Step-by-step explanation:

✓121=121^1/2 =11

2*22/7 = 44/7 = 6.2

✓130=11.4

Answer from great to least = 11.4,11.1,11,6

Answer:

x=7

Step-by-step explanation:

2x+3(x-1)=3x+11

Step-by-step explanation:

Convert the Oz to pounds and add them.

Answer:

Tim has -8 points.

Step-by-step explanation:

15 - 23

Another way to solve for this is reversing the order the numbers are shown:

23 - 15

Just remember the answer will be negative because Tim is losing more points than he originally had.

-8

Answer:

B.16 mins start from home to school or school to home

Step-by-step explanation:

I. When bike is faster than walk 3 times

  Jane is in the middle of way to school

  if she walk mid point to school is 4 mins

 then mid point to home is 4 * 3 = 12 mins

 School + Home = Total Mins

 4 + 12 = 16

Answer:

1) 6/10

2) 16/100

Step-by-step explanation:

1/3x18

2/5x40

of = multiply

Answer:

10

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] × 18 = 18 ÷ 3 = 6

[tex]\frac{2}{5}[/tex] × 40 = (40 ÷ 5) × 2 = 8 × 2 = 16

Difference = 16 - 6 = 10

Answer:

Step-by-step explanation:

Like terms are terms that have same variable with same power.

Combine like terms.

5a - 6b - 3a - 2b = 5a - 3a  - 6b - 2b

                           = 2a - 8b

Answer:

x = 15.008

Step-by-step explanation:

9^2 + x^2 = 17.5^2

x^2=225.25

x = 15.008

Answer:

x is all real numbers

Step-by-step explanation:

4(x + 1) = 4x + 4

Distribute

4x+4 = 4x+4

Subtract 4x from each side

4x+4-4x = 4x+4-4x

4=4

This is always true so there are infinite solutions

x is all real numbers

An inference is something that is not directly stated by logical deduction can be a reasonable conclusion to a conclusion drawn.

Example

There was a  person standing in front of me waiting for a bus. I made it guess that it was a girl because she was wearing pink shoes and had a pink phone in her back pocket.

I know that's a bit sexist, but I could not think of another answer. You should, however, note the evidence.

Answer:

80.77777778

Step-by-step explanation:

when dividing 727 by 9, think about how many times does 9 go into 7? none.

next how many times does 9 go into 72? 8 times!

but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

Answer:

[tex] \frac{4}{9} [/tex]

Step-by-step explanation:

First add the two values

=⅓+⅑

LCM=9

=⅓x3+⅑

=

[tex] \frac{3}{9} + \frac{1}{9 } = \frac{4}{9} [/tex]

Answer:

50 degrees

Step-by-step explanation:

All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.  

45+85=130.  Then, subtract 130 from the total, or 180.   180-130=50. The measure of the third angle of the triangle is 50 degrees.
