The distance of the two points equals to
Answer:
they are equal
Step-by-step explanation:
1 dime is equal to 10 pennies
so 45x10 = 450
450=450
Yanira = Y
Tim = T
Hannah = H
-----------------
Therefore:
Y=T+3
Y=2H
T=H+2
---------------
Now, we know that:
Y=T+3
But we also know that:
T=H+2
Therefore:
Y=(H+2)+3
Y=H+5
-------------------
Now we can combine the equations:
Y=H+5
Y=2H
Therefore:
2H=H+5
2H-H=5
So, H=5.
---------------------
If H=5,
Y=2H=2*5=10
---------------------
If H=5,
T=H+2=5+2=7
-----------------------
Answers:
Yanira is 10 years old.
Tim is 7 years old.
Hannah is 5 years old.
A.
the 2 quantaties are
ricky's distance and greg's distance
it should be total 8 miles
B. ricky distance=ricky rate times ricky time
ricky distance=1.5*3
ricky distance=4.5 miles
ricky distance+greg distance=8
4.5+gdistance=8
minus 4.5 both sides
gdistance=3.5
gdistance=grate time gtime
3.5=2 times time
divide both sides by 2
1.75=time
greg walked 1.75 hour
not sure how to do variable thing and what goes where
ricky walked 4.5 miles
greg walked 1.75 hour and traveled 3.5 miles
32 / (14 2/9) =
32 / (128/9) =
32 * 9 / 128 =
288 / 128 =
