Answer:
B
Step-by-step explanation:
Answer:The equation would be 230 = 25y + 10x + 1x or 230 = 25y + 11x
You would then need to solve for x and y, which I forget how to do with 2 variables but since we're working with small numbers what I would do is continuously subtract 25 from 230 until the remainder is divisible by 11.
230 - 25*7 = 55 = 11*5
x = 5
Ok, adding the equation 2x+y = 17 you will now be able to solve for the two variables using a system of equations.
yes, you can come up with an equation. actually, you can come up several equations to generate a system of equations.
your first equation is correct.
(1) 25q + 10d + 1p = 230
now, you're told that the number of dimes equals the number of pennies. that just means, in symbols:
(2) d = p
finally, you're told that you have 17 coins in all, i.e.:
(3) q + d + p = 17
you now have three equations and three unknowns. use (2) to reduce (1) and (3).
(1′) 25q + 11d = 230
(3′) q + 2d = 17
now solve for the three variables.

at the bottom. (or used the attached picture for reference)
One thing to note, however, is that the side opposite
is the same side as the one adjacent to
! Thus
.
Substitute these values for
and
and solve.
60 times 3/5 = 36. 20 times 3/5 = 12. 12 + 36 = 48. Javar scored a total of 48 points.
