Answer:
Omar saved 10 dollars in total
Step-by-step explanation:
total= 2.5*4
total= $10
Answer:
A = B + 15
Step-by-step explanation:
Let Diane sold B books in one hour,
Additional earning by selling 1 book = 1$
Additional earning by selling B books = Number of books sold × Additional earning by selling one book
= B × ($1.00)
= $B
Fixed earning of Diane in one hour of part time = $15
Total earnings = B + 15
A = B + 15
Table to find the input-output values for the graph,
A 15 16 17 18
B 0 1 2 3
Now we can plot the points on the graph.
Answer:
The answer is b.
Step-by-step explanation:
You need to find the total distance and the total time. The total distance is two times the distance to school, 2d.s=d/t=>t=d/sWhere s is speed, d is distance and t is time. So the time taken to get to school is:d/s1and the time taken to get back is:d/s2so the total time is:d/s1+d/s2=d(1/s1+1/s2)So, as speed = distance/time, divide the total distance by the total time:2d/d(1/s1+1/s2)=2/(1/s1+1/s2)=2/(1/20+1/40)=80/3≈26.7km/hr
Answer:

Step-by-step explanation:
Given: GCF of two numbers is
. neither number is divisible by the other.
To Find: smallest of these two number.
Solution:
As GCF of two numbers is
, both number are divisible by
.
Prime factor of

multiples of
are 


GCF of all three multiples is
,
Here
and
are the two multiples whose GCF is
and neither is divisible by other
Hence the smallest of two is
, the answer is
