Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
heyy me again
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21

Step-by-step explanation:
Gradient is just another similar term for slope l, 
, and it can be calculated by 
where 
and 1
is the 
-coordinates of point 
We let 
be point 
and 
be point 
, we can then write the equation:
.
It also says that the points are with a gradient of so 
. We can then write the equation:
