Answer:

I did the first page you asked for just now! :)

Step-by-step explanation:

20)  15 = 3r    R = 5

21)   k/2 = 6    K = 12

22)  3h = 27   H = 9

23)   j/3 = 4     J = 12

24)  6p = 30   P = 5

25)  n/10 = 40   N = 400

26)  h/4 = 15   H = 60

27)  9/s = 81   S = 9

28)  14 = 2c   C = 7

29)  26 = 13d   D = 2

30)  6 = m/3   M = 18

31)  7 = p/5   P= 35

32)  4w = 16   W = 4

33)  f/3 = 9   F = 27

34)  20 = 4x   X = 5

35)  3z = 36   Z = 12

36)  10 = j/6   J = 60

Answer: JG= 12.
Explantation: Since it is a parallelogram, we know that EJ and JG are congruent (equal). Therefore, we set EJ and JG as an inequality. (3w = w + 8) We solve for W and get w=4. Plug in 4 into the JG equation (4 + 8). The answer would be 12.

You purchase 5 pounds of apples and 2 pounds of oranges for $9.Your friend purchases 5 pounds of apples and 6 pounds of oranges
babymother [125]

Answer:

x = 1 and y = 2

Step-by-step explanation:

Let apples are represented by x

and let oranges are represented by y

You purchase 5 pounds of apples and 2 pounds of oranges for $9. This line in equation format can be written as:

5x + 2y = 9

Your friend purchases 5 pounds of apples and 6 pounds of oranges for $17.

This line in equation format can be written as:

5x + 6y = 17

Now we have two equations:

5x + 2y = 9 -> eq (i)

5x + 6y = 17 -> eq(ii)

We can solve these equations to find the value of x and y.

Subtracting eq(i) from eq(ii)

5x + 6y = 17

5x + 2y = 9

-     -         -

_________

0+4y= 8

=> 4y = 8

y= 8/4

y = 2

Now, putting value of y in eq (i)

5x + 2y = 9

5x +2(2) = 9

5x +4 = 9

5x = 9-4

5x = 5

x = 1

so, x = 1 and y = 2

Find the 10th term of the sequence if the explicit function/formula is f(n)=100+10n
Nutka1998 [239]

Answer:

The 10th term of the sequence is 200.

Step-by-step explanation:

Given that,

The sequence is as follows :

f(n)=100+10n

We need to find 10th term of the sequence.

Put n = 10 in the given expression.

f(10)=100+10(10)

= 100 + 100

= 200

Hence, the 10th term of the sequence is 200.
