The answer is 5/1 because reciprocal means to flip a fraction.
Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60
Answer: x=-2
Step-by-step explanation:
y=x+1
y=-x-3
-x-3=x+1
-4=2x
x=-2
Answer:
721
Step-by-step explanation
700 divided by 100 is 7.
So you have 7 hundred and 7 times 3 is 21.
700+21=721
A triangle angles all add up to 180 degrees and you have a 90 and 40 degree angle so you are at 130 degrees so the answer is B) x=50 degrees
