One number is seven more than six times another number. If the sum of the numbers is 21, find the numbers

Answers

Answer:the two numbers are 2 and 19

Step-by-step explanation:

Let one of the numbers be x

and the second be 7+ 6x

so that the sum of the two numbers which totals 21 be expressed as

x + (7+ 6x) = 21

x+ 7+6x= 21

7 + 7x = 21

7x= 14

x= 14/7 = 2

one of the numbers = 2

the other number given as

7+ 6x = 7+ 6 x 2= 7+12= 19

The numbers are 2 and 19 .

The numbers as described in the question are; 2 and 19

Solving word problems

From the given problem statements;

The first number = y

The second number = x

Hence, y = (7 + 6x)

Their sum is therefore;

x + 7 = 6x = 21

7x = 14

x = 2

Hence, the second number is; 7 + 6x = 7 + 6(2);

y = 19

Find the 18h term of the arithmetic sequence whose common difference is d=4 and whose first term is a, =3.

Answers

Answer:

the 18th term is 71

Step-by-step explanation:

The general form for any term "n" in an arithmetic sequence is:

a(n) = a1 + (n-1) * d

where "d" is the common difference.

So, in our case we have:

a(n) = 3 + (n-1) *4

Therefore, the 18th term will be:

a(18) = 3 + (18 - 1) 4 = 3 + 17 * 4 = 71

Answer:

1. x = 65

2. x = 40

3. x = -7

4. x = -4

5. x = -7

6. x = 4

Step-by-step explanation:

Angles in a triangle always add up to 180 degrees.

Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.

1. 180 = 80 + 35 + x

180 - (80 + 35) = x

180 - 115 = x

65 = x

2. 180 = 70 + 70 + x

180 - (70 + 70) = x

180 - 140 = x

40 = x

3. 180 = 76 + 41 + (x+ 70)

180 - (76 + 41) = x + 70

180 - 117 = x + 70

63 = x + 70

63 - 70 = x

-7 = x

4. (the red square means its a right angle = 90 degrees)

180 = 90 + 25 + (x + 69)

180 - (90 + 25) = x + 69

180 - 115 = x + 69

65 = x + 69

65 - 69 = x

x = -4

5. 180 = 50 + (57 +x) + (x + 87)

180 - 50 = (57 +x) + (x + 87)

130 = (57 +x) + (x + 87)

combine like terms

130 = 144 + 2x

130 - 144 = 2x

-14 = 2x

-7 = x

6. 180 = 80 + (9x + 4) + (16x - 4)

180 - 80 = (9x + 4) + (16x - 4)

100 = (9x + 4) + (16x - 4)

combine like terms

100 = 25x + 0

100 = 25x

4 = x

A. Find velocity and acceleration at t = 4.3 s.
Round your answers to 2 decimal(s).
v(t) =
a(t) =

Answers

Given the position function

s(t) = 3 - cos(t )

differentiate once to get the velocity, and twice to get the acceleration:

v(t) = s'(t) = sin(t ) → v (4.3 s) ≈ -0.92

a(t) = s''(t) = v'(t) = cos(t ) → a (4.3 s) ≈ -0.40

The acceleration is negative, so the particle is slowing down.

Which proportional relationship has the greatest rate of change?

Answers

Answer:

Option (1) ; y = 7x

Step-by-step explanation:

(1) reads y = 7x, a line with slope 7, therefore the rate of change in this is 7

(2) says that y increases 12 units every time that x increases 4 Then the rate of change is: (increase in y / increase in x = 12/4 =3

(3) shows a table from which we can see that an increase of y in 8 corresponds to an increase of x in 2: rate of change = (8 - 0) , (2 - 0) = 4

(4) shos a line with slope (rate of change) given by: (12 - 0) / (2 - 0) = 12/2 = 6

Therefore, the greatest rate of change is shown by the first expression

y = 7 x
