90/3 parts of silver = 30 times multiplied by
tin = 12 × 30 = 360g
lead = 8 × 30 = 240g
12.5 / 23 = 0.5434 parts per metal
tin = 12 × 0.5434 = 6.5kg
lead = 8 × 0.5434 = 4.5kg
silver = 3 × 0.5434 = 1.5kg
Answer:
Step-by-step explanation:
Let's examine the individual things
A. x=0 --> y=3.0-5=-5 True
B. x=-1 --> y=3.(-1)-5=-8 False
C. x=5/3 -->y=3(5/3)-5=0 True
D. x=2 --> y=3.2-5=1 True
Answer is B.
You don't understand, you can ask me :)
Answer:
so a perpendicular line's slope will be the opposite reciprocal
in 4r-10y=40 the slope of this line is 4/10(-a/b). So the slope of the perpendicular line would be -10/4 (-5/2) hope this helps!
Answer:
(A) Is right
Step-by-step explanation:

put X= -2. in y = X+3
to get y 's value
Y = -2+3
= 1
therefore, your solution is ( -2,1)
For number two, to get the area, multiply 6 and 14 which is 84. C is the answer. I can’t see 3.
