Answer:

4/5

Step-by-step explanation:

8/15 = 8/15

3/5 = 9/15

2/3 = 10/15

11/15 = 11/15

We see that the pattern is that the terms increase by 1/15 as they move up.

Thus, the next term in the sequence is 12/15, which can be simplified to 4/5.

Answers

Answer: A
Explanation:

y + 3x = -1
y = 1/2x+ 20

Answers

im not sure if it’s right but I think it’s -6,17
So you can substitute equation 2 in equation 1.

U believe your equation 2 should read y= x/2 + 20 (the x is next to the 1 and not to the 2, right)

So after substituting, we have:

(x/2)+20+3x = -1

Multiply the whole equation by 2:

x + 40 + 6x = -2
7x = -2-40
7x = -42
x = -6

Replace x=-6 in equation 1:

y + 3(-6) = -1
y - 18 = -1
y =17

Answer:

Step-by-step explanation:

In rectangle, diagonals bisect each other and diagonals are equal.

So, AE = DE

∠ADE = ∠DAE            {Angles opposite to equal sides are equal}

6x - 1 = 2x + 15

6x      = 2x + 15 + 1

   6x = 2x + 16

6x -2x = 16

4x      = 16

       x = 16/4

       x = 4

∠ADE = 6x - 1

         = 6*4 - 1

         = 24 - 1

        = 23

The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity gets added to the bill.

If the dentist fills n cavities, what will be the cost of the visit to the dentist?

Write your answer as an expression.

Answers

Answer:

The expression for the total cost of the visit to dentist is T = 50 + 100n .

Step-by-step explanation:

As given

The price of a visit to the dentist is $50.

If the dentist fills any cavities, an additional charge of $100 per cavity gets added to the bill.

If the dentist n cavities .

Let us assume that the total cost of the visit to dentist be T.

Than the expression becomes

T = 50 + 100n

Therefore the expression for the total cost of the visit to dentist is T = 50 + 100n .

A price is increased by 5% and is now £756.
Work out the original price.

Answers

Answer:

£720

Step-by-step explanation:

100+5 = 105

105% = 756

divide both sides by 105 to find 1%

1% = 7.2

multiply both sides by 100 to find 100%

100% = 720

756/105 X 100 = 720

Answer:

number 5:4/12

#6: 25/45

#7: 26/44

#8: 52/30

Step-by-step explanation:

Answer:

5) 1/3=x/12

12=3x

3x=12 (divide both sides)

12 divided by 3 = 4

therefore, x = 4

6) 5/9=25/y (cross multiply the numbers)

after cross multiplying you should get: 5y=225

divide both sides to get 45

therefore, y = 45

7) 26/z = 13/22 (cross multiply numbers)

after cross multiplying, you should get: 572=13z (swap the numbers)

after swapping the number, you should get: 13z=572 (divide both sides)

after dividing you should get 44

therefore, z = 44

8) b/30 = 2.6/1.5 (simplify expression)

after simplifying you should get: b/30=26/15 (cross multiply after)

after cross multiplying you should get: 15b = 780 (divide both sides)

after dividing both sides, you should get: 52

therefore, b = 52
