Answer: 8 1/4
Step-by-step explanation:
2 3/4 + 5 1/2 = ?
Least common denominator is 4
2 3/4 + 5 2/4 = ?
2(4)+3 = 11
5(4) + 2 = 22
so the equation becomes
11/4 + 22/4 = 33/4 = 8 1/4
Answer:
2x = 2x
Step-by-step explanation:
2x + 6 = 3x + 6 - x
2x = 3x - x(cancel equal terms)
2x=2x
Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour
Answer
B volume and temp
Step-by-step explanation:
The cup is telling you the volume in the cup and the temp stick thing is telling you temp. Hope this helped
Sorry for the hand writing. But you want to factor out a 4y^2 which will result in (9y^2-1). Then you will factor out the equation in parentheses to (3y-1)(3y+1). Don’t forget to put the 4y^2 out front!
