Answer:
c. t = 18; the Chang family has been driving for 18 hours
Step-by-step explanation:
Given:
D(t) = 2,280 - 60t
Find t when D(t) = 1,200
D(t) = 2,280 - 60t
1200 = 2280 - 60t
Subtract 2280 from both sides of the equation
1200 - 2,280 = 2280 - 60t - 2,280
- 1080 = - 60t
Divide both sides by -60
- 1080 / -60 = - 60t / -60
18 = t
t = 18
This means the Chang family has been driving for 18 hours
c. t = 18; the Chang family has been driving for 18 hours
bro which class question is this then I can help you with ur question
The given number is 3.75, we will read the number separately first as follows:
before the decimal point we have 1 3 which is read as three
after the decimal point we have a .75 which is read as seventy-five hundredth
So, combing the two parts, we can find that the word form of 3.75 is:
three and seventy-five hundredth.
Step-by-step explanation:
Given
y = x + 3.....equation 1
y = x - y
or y + y = x
or 2y = x
or y = x / 2......equation 2
Now
Putting equation 2 in equation 1
x / 2 = x + 3
x - x/2 = - 3
<u>2x</u><u> </u><u> </u><u>-</u><u> </u><u>x </u> = - 3
2
x / 2 = -3
x = - 6
Now
y = x/ 2
= - 6/2
= - 3
Hope this helps
