Answer:

m = - 1

Step-by-step explanation:

Given

- 9m - 86 = - 75 + 2m ( subtract 2m from both sides )

- 11m - 86 = - 75 ( add 86 to both sides )

- 11m = 11 ( divide both sides by - 11 )

m = - 1

Answer:

∠ ABD = 19°

Step-by-step explanation:

Since AB and BC are congruent, then Δ ABC is isosceles and the base angles are congruent, that is

∠ BAD = ∠ BCD = 71° , thus

∠ ABC = 180° - (71 + 71) ← angle sum of triangle

∠ ABC = 180° - 142° = 38°

DB is an angle bisector , thus

∠ ABD = 0.5 × 38° = 19°

Answer:

10

Step-by-step explanation:

75c-300=25c+200

-25c         -25c

50c-300=200

+300         +300

50c=500

c=10

Final Answer: [tex]c = 10[/tex]

Steps/Reasons/Explanation:

Question: Solve for the given variable: [tex]75c - 300 = 25c + 200[/tex].

Step 1: Add [tex]300[/tex] to both sides.

[tex]75c = 25c + 200 + 300[/tex]

Step 2: Simplify [tex]25c + 200 + 300[/tex] to [tex]25c + 500[/tex].

[tex]75c = 25c + 500[/tex]

Step 3: Subtract [tex]25c[/tex] from both sides.

[tex]75c - 25c = 500[/tex]

Step 4: Simplify [tex]75c - 25c[/tex] to [tex]50c[/tex].

[tex]50c = 500[/tex]

Step 5: Divide both sides by [tex]50[/tex].

[tex]c = \frac{500}{50}[/tex]

Step 6: Simplify [tex]\frac{500}{50}[/tex] to [tex]10[/tex].

[tex]c = 10[/tex]

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40

Answer:it is ten

Step-by-step explanation:

The probability is the ratio of the favorable event to the total number of events. Then the probability that both suits will be black is 0.183.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

A clothing store has 18 suites for sale. 10 of the suits are Blue, and 8 are black. Two suits are chosen to be put on display in the store window.

Then the probability that both suits will be black will be

[tex]\rm P = \dfrac{ ^8C_2 \times ^{10}C_0}{^{18}C_2}\\\\P = \dfrac{28 \times 1}{153}\\\\P = 0.183[/tex]
