Answer:

1 2/7

Step-by-step explanation:

18 - 2x(4+3) =

combine like terms in the parentheses

18 - 2x(7) =

Multiply

18 - 14x  (This is the value of the expression)

We can solve for x by setting it equal to zero

18 - 14x = 0

-14x = -18

x = -18/-14

x = 1 2/7

2.46

I think.

Because if you multiply 6 and 0.41 you get 2.46.

Answer:

2.46

Step-by-step explanation:

x/6=0.41

Multiply 6 on both sides and you get 2.46

Answer:

I think because the absolute value is always a positive number.

Answer:

23.5 feet per minute is the rate

Answer:

Step-by-step explanation:

a1 = 2

d = 7

n = 13

I take it you want the 13th term.

t_13 = a1 + (n - 1) * d

t_13 = 3  + (13 - 1) * 7

t_13 = 3 + 12*7

t_13 = 3 + 84

t_13 = 87

Hi again

Its your 3rd option

Step-by-step explanation:

Answer:

Step-by-step explanation:

Option 3 is correct just got the test!

Answer:

(m+8) - 2

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Since C is the midpoint of BD, BC must be equal to CD. Therefore, we can set the equation:

x+4=3x-10

Solve:

14=2x

x=7

Then we find AC, which is:

2x-5+x+4 = 3x-1

We can plug x in to get:

3*(7)-1=20

The answer:  a° = 180° - 62° = 118°    ,     b° = 62°  ,     c° = (180° - 62°) ÷ 2 = 59°

Ok done. Thank to me :>

Answer: start out with -10=10 x n-9

next divided 10. -10 divided by 10 = -1

-1 = n-9

now add 9 to both sides

8 = n

there is your solution!!!

Answer: Score on a science test, D, Average temperature

Step-by-step explanation:

A: Score on a science test(dependent variables are the "effects" of the independent variable, and number of hour studied results in the score on the science test)

B: D (the input will always remain the same but the output is dependent on the independent variable, so in this case the input is the independent variable)

C:Average temperature( the temperature depends on how far it is from the equator, thus making it the dependent variable in this relationship)

Hope it helps!

Answer:

2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2. Now we collect the factors, so our final answer is 60 = 5 x 3 x 22.

The distance between points A (3, -5) and A' (2, -3) is 2.4 units.

Given that,

The points A (3, -5) and A' (2, -3).

We have to determine,

The distance between point A and A'.

According  to the question,

The distance between two points is determined by using the distance formula.

[tex]\rm Distance \ formula = \sqrt{(x_2-x_2) ^2+ (y_2-y_2)^2[/tex]

Then,

The distance between points A (3, -5) and A' (2, -3) is,

[tex]\rm Distance = \sqrt{(2-3) ^2+ ((-3)-(-5))^2}\\\\ Distance = \sqrt{(-1) ^2+ (2)^2}\\\\ Distance = \sqrt{1+4}\\\\Distance = \sqrt{5}\\\\Distance = 2.4 \ units[/tex]

Hence, The distance between points A (3, -5) and A' (2, -3) is 2.4 units.

Answer:

These results, 7 and 9, have a product of 63, as stated.

Step-by-step explanation:

Represent the first odd number by x and the first consecutive odd number by x + 2.  Then the product of these two numbers is x(x + 2) and it equals 63.

Solve for x.  Perform the indicated multiplication, obtaining

x^2 + 2x - 63 = 0

Solve this by factoring:  (x + 9)(x - 7) = 0

Then x could be either -9 or +7.  If we let x = 7 then the first consecutive odd number is 7 + 2, or 9.  These results, 7 and 9, have a product of 63, as stated.

Answer:

  t[1] = 120; t[n] = t[n-1]/n, n ≥ 2

Step-by-step explanation:

The first two terms have a ratio of 1/2. The next two terms have a ratio of 1/3. The terms after that have a ratio of 1/4. It seems that the divisor increases as n increases. In fact, the n-th term is the previous one divided by n.

The first term is 120, so ...

  t[1] = 120

Using the above-described rule, ...

  t[n] = t[n-1]/n . . . . for n ≥ 2
