Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2
Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300

Answer:
missing length is 8
Step-by-step explanation:
17^2 - 15^2 = 64
square root of 64 is 8
Answer:
8 inches
Step-by-step explanation:
Use the Pythagorean Theorem:
a²+b²=c²
15²+b²=17²
225+b²=289
b²=64
b=8
Therefore, the missing side is 8 inches long.
solve (i) 4/15+x=17/30
Answer:
3/10
Step-by-step explanation:
4/15+x=17/30
x=17/30-4/15
x=17/30-8/30
x=9/30
simplify
x=3/10
A kind teacher gives you 20 cents for every question you get right, but you have to pay the
teacher 10 cents for every question you get wrong. After 30 questions you have made a
profit of $1.80.
a ) Form an equation with x representing the number of questions you got right.
b )Solve your equation to find how many questions you got right.
Answer:
Let n be the number of questions you got right. Then
30-n equals the number of questions you got wrong.
So:
A) 20n-10(30-n)=180
30n-300=180
30n=480
n=16
30-n=14
B)You got 16 questions right and 14 questions wrong.

A biologist was sitting near a pond and noticed a large number of dragonflies. He also saw both frogs and fish trying to eat the
dragonflies. He counted a total of 89 fish, frogs, and dragonflies. He noticed that there were four times as many dragonflies as fish and
that the frogs were five more than twice the number of fish
89 /3
frogs = 29.6
fish = 29.6
dragonflies = 29.6
all of them equal 89

Simplify:
-2(3x-1) + x(3x+2)
Answer:
-4x+3x power of 2 +2
Step-by-step explanation:
Answer:
3x² - 4x + 2
Step-by-step explanation:
distribute -2 into (3x - 1) and distribute x into (3x + 2)
=> -6x + 2 + 3x² + 2x
combine like terms
=> 3x² - 4x + 2
