2a+3c=56, a+4c=49.50
2a+3c=56.00
-2(a+4c=49.50)
_______________
2z+3c=56
-2a-8c=99
____________
0+-5c=-43
-5c=-43
c= -43/-5
child ticket=8.60
now take c and plug the answer into the first equation: 2a+3c=56, 2z+3(8.60)=56, 2z+25.80=56, 2a=56-25.80, 2a= 30.20, a=30.20/2, adult tickets =15.10
This is for 30cm not 48 but you can find out how to do it. This is an example
Answer: 145
3.7 x 60 = 222 (how far north she drove)
1.4 x 55 = 77 (how far south she drove)
222 - 77 = 145 (how far from home)
No, <span>hypotenuses of these two triangles won't lie along the same line </span><span>because one is larger than the other

Answer:
So in scientific form 4000 miles will be equal to 
Step-by-step explanation:
We have given that radius of earth is 4000 miles
4000 miles can be written as 4×1000
We have to written 4000 miles in scientific form
We know that 1000 can be written in scientific form as 
So 
So in scientific form 4000 miles will be equal to
