Add 1 3/7 and leave it like that, and then do 9x3=27+5=32 so it’s gonna be 32/9 and then calculate the sum into 691/126 or u can divided more into 5 61/126

Answer:

The correct answer is 5 61/126!

Step-by-step explanation:

Leave a fraction alone

1 3/7

Find the Addend

9x3=27+5=32 = 32/9

Find the sum and simplify

1 3/7 + 32/9 = 691/126 = 5 61/126

Continue the pattern 10,6, 18, 14, 26, 22, 34

garri49 [273]

Continuing the pattern we get: 10, 6, 18, 14, 26, 22, 34, 30, 42, 38

<h3>Solution:</h3>

The given pattern is: 10, 6, 18, 14, 26, 22, 34

Let us first analyse the pattern and find out the logic

The logic used is:

10 - 4 = 6

6 + 12 = 18

18 - 4 = 14

14 + 12 = 26

26 - 4 = 22

22 + 12 = 34

34 - 4 = 30

30 + 12 = 42

42 - 4 = 38

Thus we can see clearly that alternatively "-4" and "+12" are being added to previous terms to find the next term in given pattern

The pattern goes like this:

10, 6, 18, 14, 26, 22, 34, 30, 42, 38

Juli2301 [7.4K]

Answer:

7/10 can't be simplified, 2/10->1/5

Step-by-step explanation:

7/10 cannot be simplified as 7 and 10 don't have any common factors other than 1

2/10 can be simplified by a factor of 2 to get 1/5

∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)

7. Which of the following can be determined from the graph below?

tatyana61 [14]

Answer:

The ordered pair (6,25) is a solution to both

$y=-\frac{5}{2}x+40$ and $y=\frac{5}{3}x+15$

Step-by-step explanation:

Part 7)

step 1

Find the equation of the line with positive slope

take the points (0,15) and (9,30)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{30-15}{9-0}$

$m=\frac{15}{9}$

simplify

$m=\frac{5}{3}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=\frac{5}{3}$

$b=15$

substitute

$y=\frac{5}{3}x+15$

step 2

Find the equation of the line with negative slope

take the points (0,40) and (8,20)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{20-40}{8-0}$

$m=-\frac{20}{8}$

simplify

$m=-\frac{5}{2}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=-\frac{5}{2}$

$b=40$

substitute

$y=-\frac{5}{2}x+40$

step 3

Find the solution of the system

we know that

The solution of the system of equations is the intersection point both graphs

The intersection point is (6,25) ----> see the graph

therefore

The ordered pair (6,25) is a solution to both $y=-\frac{5}{2}x+40$ and

$y=\frac{5}{3}x+15$
