The number of calories in a piece of pie is 20 less than three times the number of calories in a scoop of ice cream. The pie and
sergejj [24]

Answer:

130 calories in the ice cream and 500 calories in the pie.

Step-by-step explanation:

Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.

4x-20=500

If we add twenty to both sides, we end up with:

4x=520

Divide both sides by four, and you get x=130.

there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.

Describe the relationship between the terms in each arithmetic sequence. Then
shtirl [24]

Answer:

(a) The sum of the previous term and 9

(b) 36, 45, 54

Step-by-step explanation:

Given

Sequence: Arithmetic Progression

0,9,18,27

Solving (a): Describe the relationship in each term

First, we calculate the common difference (d)

In arithmetic progression:

d = T_n - T_{n-1}

Take n as 2

d = T_2 - T_{2-1}

d = T_2 - T_{1}

Where

T_2 = 9\ and\ T_1 = 0

d =9-0

d =9

<em>The relationship is: The sum of the previous term and 9</em>

Solving (b): The next three terms

As said in (a) each term is derived from a sum of 9 and the previous term

So, we have:

Next\ Term = 27 + 9 = 36

Next = 36 + 9 = 45

Next = 45 + 9 = 54

Hence, the next three terms are: 36, 45 and 54

What is 9 10????????????????????????????
kozerog [31]
9+10=?
9 = 3x3
10= 5x2
3 (from 3x3) x 5 (from 5x2) = 15
3 (from 3x3) x 2 (from 5x2) = 6
15+6=21
Therefore 9+10=21
