∠ABD and ∠BDE are supplementary. Find the measures of both angles.
Gnom [1K]

Supplementary means that the angles have to add up to 180, so you have your equation.

180=5x+17x-18

198=22x

x=9

Then to find the measures of the angles, you plug x back in.

m∠ABD=5(9)=45 degrees

m∠BDE=17(9)-18=153-18=135 degrees

A pearl is formed in 1 of every 10,000 oysters. What percent of oysters make pearls? Hint: An answer of 1, percent would mean 1
zysi [14]
It would be 0.001 because if 1 is for 100 oysters, then you would add two zero's in front and move the decimal point over twice, therefore you get 0.001% as your answer.

(m-3)/(7)=(m)/(m+8) Solve the proportion.
ExtremeBDS [4]

Answer: m=6, m=-4

Step-by-step explanation:

To solve this proportion, we have to cross multiply.

\frac{m-3}{7} =\frac{m}{m+8}

(m-3)(m+8)=7m

Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

m^2+8m-3m-24=7m

Combine like terms.

m^2+5m-24=7m

We can move all terms to one side and then solve for m.

m^2-2m-24=0

We can actually factor this to:

(m-6)(m+4)=0

We set each factor equal to 0 to find m.

m-6=0

m=6

m+4=0

m=-4
