Solve the equation: 2 1/2 = 5n

Answer:

1. x=-5

2. x=24

3. -1x+19

4. 14w²-4w

5. 5x-15

6. 11a²b-12ab²

7. 6x+4

8.  x=15

9. x=-12

10. x=3

11. x=20

Step-by-step explanation:

1.

15x-24-4x=-79      We have to add the like terms

     +24        +24

15x-4x=-55             Subtract 15x-4x

11x=-55             Now divide

/11      /11

x=-5

2.

3(2x-5)-4x=33           Use distributive property

6x-15-4x=33            Add like terms

    +15      +15

6x-4x=48            Subtract 6x-4x

2x=48            Divide

/2    /2

x=24

3.  

6x+4+15-7x             Combine 6x and -7x

-1x+4+15         Now combine 4 and 14

-1x+19

4.

6w²+11w+8w²-15w            Combine 11w and -15w

6w²+8w²-4w                  Now combine 8w² and 6w²

14w²-4w

5.

12x-5-7x-11            Combine -5 and -11

12x-7x-15        Now subtract 12x-7x

5x-15

6.

11a²b-12ab²

Nothing else can be done with this equation

7.

2(3x+2)

6x+4

8.

x/5=3

5×3=15

15=x

9.

2/3x=-8

-4×2=-8

-4×3=-12

x=-12

10.

9x-11=-38

    +11  +11

9x=-27

/9     /9

x=3

11.

-x/5+3=7

       -3  -3

-x/5=4

-x=-20

x=20

Answer:

[tex] \frac{1}{81} [/tex]

Step-by-step explanation:

express that with a positive exponent using this:

[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]

so ..

[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]

now you have to evaluate the exponent/ power

so..

[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]

why 81 ?

because the exponent of 9 is 2 so you have to multiple 9 by itself so

9x9=81

so the answer is

[tex] \frac{1}{ {81}^{} } [/tex]

sorry for the bad english hehe

Answer:

$13.69

Step-by-step explanation:

16.10 decrease 15% =

16.10 × (1 - 15%) = 16.10 × (1 - 0.15) = 13.685

Answer:

30 cubic feet

Step-by-step explanation:

Answer:

$18.19

Step-by-step explanation:

20 decrease 15% =

20 × (1 - 15%) = 20 × (1 - 0.15) = 17

17 increase 7% =

17 × (1 + 7%) = 17 × (1 + 0.07) = 18.19

Answer:

At my school I don't get too much homework. My county doesn't have classes  on Wednesday so usually my teachers give work on Monday that is due on Wednesday and then work on Thursday due in Sunday. Also I only get homework for 3 classes Math, S.S and ELA, not science.

Answer:

[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]

Step-by-step explanation:

Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,

[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]

On substituting the respective values :-

[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]

Answer:

4.5(1.035)^t

Step-by-step explanation:

An inrease of 3.5% means that each year's total is 103.5% of the year before, right?

Year 1 = 4.5(1.035) = 4.66

Year 2 = 4.66(1.035) = 4.82

etc.

So, year 2 is 4.5(1.035)(1.035) = 4.82

Multiplying something by itself can be written with an exponent instead, so 2 years is...

4.5(1.035)2

Since the number of years is the variable (let's call it t)...

Answer:

Step-by-step explanation:

i² = -1

i⁵ = i² * i² * i

  = (-1) * (-1) * i

i⁵ = i

i²⁵ = i ⁵ˣ⁵ = (i⁵)⁵

   = (i)⁵

  = i

Inequality Form:

2 − √ 11 < x < 2 + √ 11

Interval Notation:

( 2 − √ 11 , 2 + √ 11 )

Step-by-step explanation:

Solve the inequality for  x  by finding  a ,  b , and  c  of the quadratic then applying the quadratic formula.

G = √m-5 /2

g² = m-5 /2

2 × g² = m - 5

2g² = m - 5

2g² + 5 = m

So, m = 2g² + 5

Answer:

m = 2G²+5

Step-by-step explanation:

G²= m-5/2

2g² = m-5

2g² +5 = m

m = 2G²+5

Answer:

All I can tell you from what you've given me is that the slope is positive, and the y-intercept is 1.
