Answer:
what do you mean
Step-by-step explanation:
?
The temperature change in a chemistry experiment was -2C every 30 min. The initial temperature was +6C. What was the temperature after 4 h
4 hours = 8 half hours
0, 1, 2, 3, 4, 5, 6, 7, 8 half hours
6, 4, 2, 0, -2, -4, -6, -8, -10
-10 degrees C
50
.25 goes into 100 4 times, 50 goes into 200 4 times :)
190 is 76% of 250
We have, 76% × x = 190
Multiplying both sides by 100 and dividing both sides by 76,
we have x = 190 × 100/76
x = 250
If you are using a calculator, simply enter 190×100÷76, which will give you the answer.
2372
You would do the equation 2332-372+412
(x - 2)/2 = 4
x - 2 = 8
x = 10
(y + 2)/2 = -3
y + 2 = -6
y = -8
(10, -8)
