So there are 18 coins in total right?(4 quarters+3dimes+5nickels+6 pennies)
So the number of pennies is 6
So probability of pennies (6) out of the whole coins(18) is 6/18 right?
This can be simplified to 2/6(since the highest common factor is 3 and dividing both by 3 gives you 2 and 6)
So probability of a pennie out of the piggy bank is 2/6
The answer to the question
Assume an x-value, substitute it in the equation where you find "x" and solve to find y
x = 0
y = -18
x = 1
y = -14
x = 2
y = -8
x = 3
y = 0
x = 4
y = 10
Answer:
A
Step-by-step explanation:
Metal is stronger than plastic, but it is also much heavier.
The key idea in this paragraph is to highlight how to transport the required materials while reducing the weight as much as possible so orbital velocity can be achieved while breaking through the resistance of the atmosphere.
This statement is the key one because it gives engineers the problem they need to find the answer to make the space exploration a reality.
