State how many solutions, 3 + 2x + 1 = 2x + 3

Answer: 26!!

Step-by-step explanation: the average is like the mean which is all 4 numbers added together divided by 4. 26 times 4 is 104. 20 +42+16  = 78. 104 - 78 is 26 so the 4th number is 26. you can check the work by adding 20 42 16 and 26 together which equals 104. 104 divided by 4 is 26!! so our answer is correct!!

Answer: The infinite geometric series converges to 38.4

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

Explanation:

Divide each term by its previous term

term2/term1 = 9.6/19.2 = 0.5

term3/term2 = 4.8/9.6 = 0.5

The common ratio is r = 0.5

Since -1 < r < 1 is true, this means the infinite geometric series converges.

It converges to...

S = a/(1-r)

S = 19.2/(1-0.5)

S = 38.4

Step-by-step explanation:

P(black or yellow) = P(black) + P(yellow) − P(black and yellow)

P(black or yellow) = 1/25 + 1/5 − 0

P(black or yellow) = 6/25

Answer:

45

Step-by-step explanation:

1) First, add 45 and 12 which equals to 57.

2)Then, subtract 12 from 57 which equals to 45.

3) Again, add 45 and 12 which equals to 57.

4) Finally, subtract 12 from 57 which leaves us with 45.

Hope this helps!

Step-by-step explanation:

Answer:f(g(0))= 1/5

              g(f(0))= 7

Step-by-step explanation:

for f(g(0))=you solve for g(x) but you plug in 0 for x so g(0)= 8(0)+3

                                                                                                    =3

 so now you plug in the answer of the function of g(x) witch is 3 and plug it in as the x for F(x) so f(3)= 1/(3)+2

                                     = 1/5

so f(g(0)) is equal to 1/5

Now for G(f(0)) you solve for f(x) by pluging 0 for x so F(0)= 1/(0)+2

                                                                                               =1/2

now you plug in 1/2 for the x of g(x) so g(1/2)= 8(1/2)+3

                                                                         = 4+3

                                                                         =7

so g(f(0)) is equal to 7

Hope this helps:)

Answer:

5(-x)

Step-by-step explanation:

Answer:= (10+5^2)*((5*-2)+9-3^3)/2

= (10+25)*((5*-2)+9-3^3)/2

= (35)*((5*-2)+9-3^3)/2

= 35*((5*-2)+9-3^3)/2

= 35*((-10)+9-3^3)/2

= 35*(-10+9-3^3)/2

= 35*(-10+9-27)/2

= 35*(-1-27)/2

= 35*(-28)/2

= 35*-28/2

= -980/2

= -490

Answer:

h = 435.779 m

Step-by-step explanation:

Step 1: Define variables

∅ = 5°

Hypotenuse (the road) = 5000 meters

We need to find height (or the vertical leg on the triangle) = h

Step 2: Use trig

sin∅ = opposite over hypotenuse

sin5° = h/5000

Step 3: Evaluate

5000sin5° = h

h = 435.779 m

Answer:

the increase of altitude is 435.8 m

Step-by-step explanation:

see attached

inclined road at 5°

after driving 5000 along the end road.

find:

increase of altitude (h)

let Ф = 5°

road = hypothenuse

using the formula Sin Ф = h ÷ hypothenuse

Sin(5) =      h      

              5000

h = Sin (5) x 5000

h = 435.8 m

therefore,

the increase of altitude is 435.8 m

angle FEB = angle ABE ( Alternate Interior Angles )

angle FEB = 4x = angle ABE

x + 4x + 65° = 180° ( sum of the Angles On the same line is equal to 18° )

or, 5x = 180° - 65°

or, x = 115/5

or, x = 23

The value of x is 23°.

4x = 4(23) = 92°.

Answer: An equation

Step-by-step explanation: In math a equal sign put in between two expressions is called an equation.    :)

Answer:

a(30) = 145

Step-by-step explanation:

a(n) = a(1) + (n-1)d

d = 5

a(30) = 0 + (30-1)5

a(30) = 0 + (29)5

a(30) = 0 + 145

a(30) = 145

Using the concept of arithmetic sequence, the value of a30, which is the 30th term of the sequence is 145

The common difference, d = 35 / 7 = 5

The nth term of an arithmetic sequence is obtained using the relation :

a1 = a2 - d = 5 - 5 = 0

Hence,

A(30) = 0 + (30 - 1)5

A(30) = 0 + 29(5)

A(30) = 145

Therefore, the value of the 30th term of the sequence is 145.

Answer:

m = $12 per week

Step-by-step explanation:

The equation would be 8m + $150 = $246. To find out how much money you earn a week, you need to solve for m.

First, subtract $150 from both sides of the equation. Doing so will leave you with an equation of 8m = $96.

Next, divide both sides by 8. This will leave you with m = $12, which is your final answer of how much money you earn a week.
