Explanation:
4x+3y=37
y=x-4
4x+3(x-4)=37
4x+3x-12=37
add 12 to both sides
7x=49
x=7
Now you use plug in x
4(7)+3y=37
28+3y=37
subtract 28 to both sides
3y=9
y=3
answer: x=7 and y=3
Answer:
8 of them are broken
Step-by-step explanation:
For the first quarter the prob is 4/10, then without replacement to find a nickel you would multiply 4/10 by 3/9 which would give you .13333.
Find opposite side
theta = 25
adjacent = 70
tangent = opposite/adjacent
tan(25) = O/70
*70 *70
70tan(25) = Opposite
