Answer:
The cost of soft drink is $0.95
Step-by-step explanation:
Let the cost of hot dog be x
Cost of 2 hot dogs = 2x
Let the cost of soft drink be y
Cost of 3 soft drinks = 3y
At a cost restaurant the cost for a hot dog and a soft drink is $2.10.
So, x+y=2.10
The cost for two hot dogs and three soft drinks is $5.15
So, 2x+3y=5.15
Plot the lines on the graph:
x+y=2.10 --Purple line
2x+3y=5.15 --- Black Line
Intersection point =(x,y)=(1.15,0.95)
Hence The cost of soft drink is $0.95
Answer:
1.78 x 10^8
Step-by-step explanation:
178000000
I usually count the number of zeros first so in this case, it would be 6
178 x 10^6
This wouldn't be standard form because the number should be between 1 and 9
178 ÷ 100 = 1.78
I divided this number by 100 so I would times 10^6 by a 100
10^6 x 100 = 10^8
the answer would be 1.78 x 10^8
i hope this helps!
if it is confusing then i am sorry
