Answer:
-9 + 21 = t t = 12°C.
Step-by-step explanation:
For this problem lets have t be equal to the original temperature in the beginning of the day. The equation -9 + 21 = t represents this situation because it states that if we add the degrees that dropped to the current degrees it will give us our original degrees. Solve. -9 + 21 = t (Simply add -9 + 21) -9 + 21 = (+12) 12 = t So, the original degrees in the beginning of the day was 12°C.
Answer:
The answer is 180 because 5×12 is 60 so 15×12 is 180
Step-by-step explanation:
(5,15)( 10,30)(15,45)(20,60)(25,75) and so on and so forth
Answer : A {-8}
-4 = b/2
-4 *2 = b
-8 = b
(x+3)-3x/2= (x-2)/4
cross multiply
4(x+3) -3x= 2(x-2)
4x+12-3x=2x-4
4x-3x-2x=-4-12
-x= -16
x=16
