8 : 6 

Now, we need to solve for the proportion.

8/6 = 28/x

Cross multiply.

8*x = 8x
6*28 = 168

8x = 168
8x/8 = 168/8
x= 168/8
x= 21

For 28 concerts, there are 21 symphonies. 

Now, set up another proportion.

8/6 = x/42

Cross multiply

8*42 = 6x
6x= 336

6x/6 = 336/6
x= 336/6
x= 56

For 42 symphonies, there are 56 concerts.

Lets answer this:-

1st lets divide to see how many times 28 goes in 8. And then we will multiply....

28 ÷ 8 = 3.5

Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:-

3.5 × 6 = 21

So, 21 symphonies are equal to 28 concerts. 

Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer. 

42 ÷ 6 = 7

7 × 8 = 56.

So, 56 concerts are equal to 42 symphonies.

Hope I helped ya!!

Solve 7x+3y=8 and 4x-y=-9 simultaneously
Jobisdone [24]

Answer: x = -1 and y = 5

Step-by-step explanation:

7x + 3y = 8 ........................... equation 1

4x - y = - 9 ............................ equation 2

Solving the simultaneous linear equation by substitution method , make y the subject of the formula from equation 2 , we have

y = 4x + 9 ............................. equation 3

substitute y = 4x + 9 into equation 1 , we have;

7x + 3 ( 4x + 9 ) = 8

7x + 12x + 27 = 8

19x + 27 = 8

subtract 27 from both sides

19x = -19

divide through by 19

x = -1

substitute x = -1 into equation 3 , we have

y = 4 ( -1) + 9

y = -4 + 9

y = 5

Therefore :

x = -1 and y = 5

This year, a small business had a total revenue of $40,700. If this is 26% less than their total revenue the previous year, what
Virty [35]
26% less than a value is best found by multiplying by (100 - 26)% = 74% = 0.74
So previous year x 0.74 = 40,700
Previous year = 40,700 / 0.74 = $55,000

What is the area of the shaded part?
makvit [3.9K]
C) 225m

Explanation:
Looking at the board we see each side is 25m in length. Each side has 5 squares, therefore the length of one side of each square is 5m (25m/5=5).

Let’s count how many full squares there are. There’s 5 completely full squares (one in the middle, and one on each of the four edges).

There’s also half-full squares which we COULD calculate separately using the area of a triangle. However, we know that two halves make one full square so let’s count how many full blocks these make up. There’s 8 triangles (or half full squares), therefore there are 4 full squares.

Adding this to the clearly full blocks shows 4+5=9. There are 9 fully shaded squares. The area of a square is A=s x s (Area = length of side x length of side). Therefore, one square’s area is 5x5=25m^2. The area of 9 squares is 25 x 9 = 225m^2.

Therefore the answer is C
