Lauryn grew p tomato plants. Padma grew 5 fewer than 3 times the number Lauryn grew. Kent grew 6 more than 4 times the number La

mojhsa [17]

Answer:

$T= 8p+1$

Step-by-step explanation:

Given :Lauryn grew p tomato plants. Padma grew 5 fewer than 3 times the number Lauryn grew. Kent grew 6 more than 4 times the number Lauryn grew.

To Find: a simplified expression to represent the total number of tomato plants that Lauryn, Padma, and Kent grew.

Solution :

Let total number of tomatoe plants be T

Since we are given that Lauryn grew tomato plants = p

We are also given that Padma grew 5 fewer than 3 times the number Lauryn grew.

⇒ $3p-5$

We are also given that Kent grew 6 more than 4 times the number Lauryn grew.

⇒ $4p+6$

So, total number of tomato plants :

⇒ $T= p+3p-5+4p+6$

⇒ $T= 8p+1$

Hence a simplified expression to represent the total number of tomato plants that Lauryn, Padma, and Kent grew is $T= 8p+1$

A,b,c are all positive integers

miv72 [106K]

9514 1404 393

Answer:

Step-by-step explanation:

We can use a number of ratio units to represent b that is the LCM of 8 and 6. That value is 24. Then multiplying the first ratio by 3 and the second by 4, we have ...

a:b = 9:24 and b:c = 24:44

Then the ratios of all are ...

a : b : c = 9 : 24 : 44

and the sum is 9+24+44 = 77.

64 teams participate in a softball tournament in which half the teams are eliminated after each round of play.

notka56 [123]

Answer:

After 6 rounds one team will win.

Step-by-step explanation:

This is an example of geometric progression,

Let p(n) represents the number of participants remaining after n rounds of play.

First term = 64

$\texttt{Common ratio = }\frac{1}{2}$

We have

$p(n)=a\times r^{n}\\\\p(n)=64\times \left (\frac{1}{2} \right )^{n}=2^{6}\times \left (\frac{1}{2} \right )^{n}\\\\p(n)=2^{6-n}$

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ

Here we need to find for what n p(n)=1

$2^{6-n}=1\\\\2^{6-n}=2^0\\\\6-n=0\\\\n=6$

After 6 rounds one team will win.

The slope of the line passing through the points (7, 5) and (21, 15) is ???

Volgvan

Answer:

(21,5)

Step-by-step explanation:

To find the slope that passes through the points (7,5) and (21,15) , we use the formula

m = (y2-y1)/ (x2-x1)

= (15-5)/(21-7)

= 10/14

=5/7

We want a slope that is 1/3 this slope so we will multiply by 1/3

5/7 * 1/3= 5/21

We know the slope and one point (0,0) we can use the same formula to figure out x and y

m = (y2-y1)/ (x2-x1)

5/21 = (y2-0)/ (x2-0)

Let the tops be equal and the bottoms be equal

5 = y2-0

5 =y2

and the bottoms

21 = x2-0

21= x2

We have the point

(21,5)
