Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478
Number of nickels plus number of dimes equals total number of coins
so
n + d = 40
then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n
we then plug that into our first equation
and get
n + 7n = 40
then we solve for n
add like terms
8n = 40
then divide both sides by 8
n = 40/8 = 5
therefore Jimmy has 5 nickels
The yellow one. the angles will always be the same no matter how small
The answer might be Y=1/4x+2
Answer:
The ship will be 
far from its port 3.5 hours from now
Step-by-step explanation:
Hi
The function is 
relates the number of kilometers y the ship will be from its port x hours from now, it has a form 
.
As the function is clearly defined, we only have to evaluate it for 
, so 
is the distance between the cruise ship and its port after 3.5 hours.
