Let's create an equation to find the # of weeks until Chad learns 937 pieces.
x = # of weeks
937 = 2x + 805
Subtract 805 from both sides.
132 = 2x
Divide both sides by 2
66 = x
Chad will need 66 weeks of lessons to learn 937 pieces.
This is impossible for a triangle to have however, your description perfectly matches a square or a rectangle
Step-by-step explanation:
First, multiply each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:
2×A=2×h2(a+b)
2A=2×h2(a+b)
2A=h(a+b)
Now, divide each side of the equation by
a
+
b
to solve for
h
while keeping the equation balanced:
2Aa+b=h(a+b)a+b
2Aa+b=h(a+b)a+b
2Aa+b=h
h=2Aa+b
Answer:
910
Step-by-step explanation:
so to find 100% ( the number)
91 x 10
910 would be the number
Answer:
To find the relative frequencies, divide each frequency from total
