G(a/2)= 2(a/2)-3
=2a/2-3
then just subtract 2a/2 by 3/1 by finding the common denominator and same for the next one.
Answer:
A.) b- 9.5 = 26.5
Step-by-step explanation:
because the equation is basically saying that (the og length) - 9.5( the one he cut out) = 26.5 ( which is the remaining wood)
This question can be answered using two ratios.
You know that 3 pounds of tomatoes can serve 5 people, giving you the ratio 3/5.
You would like to know how many pounds would serve 110 people, giving you the ratio x/110.
Since the ratio of tomatos to people is a constant, you can set the two ratios equal.
3/5 = x/110
Now you would solve for x by cross multiplying.
110*3 = 5*x
330 = 5x
330/5 = x
66 = x
This means 66 lbs of tomatoes can serve 110 people.
Answer:
d=4
Step-by-step explanation:
SUM OF 15 terms = 615
T5 = 53
T5 = a+(n-1)d
53 = a + 4d
4d = 53 - a
d = (53-a)/4
S15 = 15/2 (2a+14d) =615
15/2 [2a + 14×(53-a)/4 ]
=15/2 [ 2a +(53×14 - 14a )/4 ]
=15/2 [ (8a +742 - 14a ) /4]
615×8 = 15(-6a +742)
-6a+72=615×8/15 =41
-6a+72=42
-6a = - 72 + 42 = -30
a = 30/6= 5
a = 5
T5 = 5 + 4×d = 53
4d= 53 - 5 = 48
4d=48
d=4
Common difference is 4
