Answer:
x=2/9,y=26/9
Step-by-step explanation:
This is a simultaneous equation
16x+5y=-2..(1)
4x-y=-2...(2)
From (2) make y the subject of formula
y=4x+2..(3)
Substitute (3) into (1)
16x+5(4x+2)=-2
16x+20x+10=-2
36x-10=-2
Add 10 to both sides
36x=8
Divide both sides by 36
x=8/36
Divide both denominator and numerator by 4
x=2/9
Substitute the value x into (3)
y=4(2/9)+2
y=8/9+2
Let the LCM be 9
y=8+18/9
y=26/9
Therefore x=2/9,y=26/9
Answer:
Step-by-step explanation:
0.1 g = 100 mg
85 mg / 100 mg = x mL / 1.5 mL
x = 1.275 mL
Answer:
You didn't say which two answers to choose from but they could possibly be 5^-4, (1/5)^4
Step-by-step explanation:
Answer:
That is an obtuse isosceles
The answer is 1 1/2 because if you divide 4 into 6 you get I need and a half or 1.5
