Answer:
Step-by-step explanation:
6x + 3y = 3 simplify by dividing both sides by 3 2x + y = 1
3x - y = 4 the 1st equation has a positive y, the 2nd has a negative y. Use elimination
to reduce them down to a single variable equation:
2x + y = 1
3x - y = 4
________
5x = 5 solve
X = 1 substitute back in to one of the original equations to find y
3(1) - y = 4
- y = 1
y = -1 (1,-1)
2x10x5
V = 100 cm3
D = 7.87 g/cm3
M = 7.87x100
= 787g
Answer:look at the angle bro and you got the angle just look at it good enough
it would be a max of 22 mins
25C=4 mins
10C*10 mins =1$
$1.25
2.10-1.25=.85
10C*8=80C
so
4+10+8=22
answer is in the above picture
32 slices are there thankyou
