what is the smallest of three consecutive integers i the sum of the smaller two integers is two more than seven times the largest integers​

Answers

Answer:

The numbers that meet these conditions are -3, -2 and -1.

This means that the wording of the question is somewhat ambiguous:

The lowest of the three numbers is -3.

The smallest however is -1.

You may need clarification on which of those is being asked for.

Step-by-step explanation:

Let's call those numbers a, b and c, with a the smallest and c the largest. We're told two key things here:

1) The sum of the smaller two integers is two more than seven times the largest integer.  In other words a + b = 7c + 2

2) We're looking for three consecutive integers, which means that we can define them with a single variable.  If the smallest one is a, then the others are a + 1 and a + 2.

We can take those and put them together, giving us the equation:

a + (a + 1) =  7(a + 2) + 2

Which we can then solve for a:

a + (a + 1) =  7(a + 2) + 2

2a + 1 = 7a + 14 + 2

2a - 7a = 14 + 2 - 1

-5a = 15

a = -3

Since a is -3 and also the smallest, we can then say that the numbers are -3, -2 and -1.

• On Monday the school bus traveled the Green Route 8 times and the Blue Route 9 times, traveling a total of 95 miles. • On Tuesday the school bus traveled the Green Route 12 times and the Blue Route 6 times, traveling a total of 102 miles

Answers

Answer: Green route = 5.8 miles

Blue route = 5.4 miles.

Step-by-step explanation:

Let the miles travelled for Green route be x

Let the miles travelled for Blue route be y

We can form an equation from the question given which will be:

8x + 9y = 95 ........ i

12x + 6y = 102 ......... ii

Multiply equation i by 12

Multiply equation ii by 8

96x + 108y = 1140 ....... iii

96x + 48y = 816 ....... iv

Subtract iv from iii

60y = 324

y = 324/60 = 5.4

Blue route is 5.4 miles.

Since 8x + 9y = 95

= 8x + 9(5.4) = 95

8x + 48.6 = 95

8x = 95 - 48.6

8x = 46.4

x = 46.4/8 = 5.8

Green route = 5.8 miles

A. -5/12
B. -12/13
C. 12/13
D. 5/12

Answers

Answer:

It’s -12/13

Step-by-step explanation:

The value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

What is the trigonometric ratio?

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

We have:

The terminal side of Ø is in quadrant IV quadrant

cosØ = 5/13

sin²Ø = 1 - cos²Ø

sin²Ø  = 1 - (5/13)²

sinØ = √(144/169)

sinØ = -12/13 (negative in IV)

Thus, the value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

See Below

Step-by-step explanation:

2x - 4 + 4x + 10 = 9x - 9

6x + 6 = 9x - 9

3x = 15  

x = 5  

UW = 9x-9 = 9*5-9  

UW = 36 units

Answer:

36

Step-by-step explanation:

UW = UV + VW

9x - 9 = 2x - 4 + 4x + 10

9x - 2x - 4x = -4 + 10 + 9

3x = 15

x = 5

UW = 9x - 9 = 9(5) - 9 = 45 - 9 = 36

Answers

Answer:

y=-1/2x+3.5

Step-by-step explanation:

solve the system of equations. y= x + 17, y= 3x+1

Answers

Answer:

x=8, y=25. As a point it's (8,25)

Step-by-step explanation:

here is the system:

y=x+17

y=3x+1

notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)

so it'll be:

3x+1=x+17

subtract 1 from both sides

3x=x+16

subtract x from both sides

2x=16

divide by 2

x=8

now, substitute 8 as x into one of the equations and solve for y

let's take the first one for example

y=8+17

y=25

so the answer is x=8, y=25. As a point it's (8,25)
