Answer:

x = 24

Step-by-step explanation:

10(x+12)=15x (Given)

10x + 120 = 15x (Distributive property of equality)

-5x = -120 (Subtraction property of equality)

x = 24 (Division property of equality)

A stone which is dropped into a dry well hits the bottom in 2.2s how deep is the well. take g=10m/s

Papessa [141]

Answer:

23.7m

Step-by-step explanation:

Given parameters:

Time taken = 2.2s

Acceleration due to gravity = 10m/s

Unknown:

Depth of the well = ?

Solution:

To solve this problem, we simply apply one of the motion equations;

S = ut + $\frac{1}{2}$ gt²

where S = depth of the well

u = initial velocity

t = time taken

g = acceleration due to gravity

Input the parameters and solve for S;

Note initial velocity = 0;

S = $\frac{1}{2}$ x 9.8 x 2.2²

S = 23.7m

7x = -67 - 11v<br> 5x = -73 - 11v

Burka [1]

Answer:

x = 3, v = -8

Step-by-step explanation:

Substitute x.

$\frac{-67-11v}{7}$

[5 • $\frac{-67-11v}{7}$ = -73 - 11v]

Isolate v.

5 $\frac{-67-11v}{7}$ = -73 - 11v

v = -8

Substitute v.

x = $\frac{-67-11(-8)}{7}$

x = 3

Sonbull [250]

Answer:

F(x) = 6x + 5.

Step-by-step explanation:

Given that :

Number of cards Given to Sébastian = 4

Number of baseball cards purchased every month = 6 cards

Number of months = x

Linear function f(x) which shows the number of cards after a number of months:

(Number of cards produced per month * Number of months) + number of card `

F(x) = 6x + 5
