Answer:

None.

Step-by-step explanation:

1 - 4 + 121

= -3 + 121

= 118

121 + 1 - 41

= 122 - 41

= 81

141 - 121

= 20

1 - 21 - 1 - 41

= -20 - 1 - 41

= -21 - 41

= -62

None of the expressions have a value of -2.

A group of scientist study the effect of chemical on Various strains of bacteria. Strain A started with 6000 cells and decreases
miskamm [114]
After h hours A has 6000 - 2000h cells and B has 2000 - 1000h. Equating them as one form:
6000 - 2000h = 2000 - 1000h
-2000h + 1000h = 2000 - 6000
-1000h = -4000
h = -4000/-1000 = 4 hours

Sum of 2 numbers is 42, and their difference is 8. What are the numbers?​
Tems11 [23]

Answer:

25 , 17

Step-by-step explanation:

Let the unknown two numbers be x & y.

According to the question,

Sum of 2 numbers is 42.

x + y = 42  ⇒ ( 1 )

Their difference is 8.

x - y = 8 ⇒ ( 2 )

First let us find the value of x.

( 1 ) + ( 2 )

x + y + x - y = 42 + 8

2x = 50

Divide both sides by 2.

x = 25

And now let us find the value of y.

x + y = 42

25 + y = 42

y = 42 - 25

y = 17

Therefore, the two numbers are 25 , 17

Hope this helps you :-)

Let me know if you have any other questions :-)
