−2(q−22)+q+12>0
Step 1: Simplify both sides of the inequality.
−q+56>0
Step 2: Subtract 56 from both sides.
−q+56−56>0−56
−q>−56
Step 3: Divide both sides by -1.
−q−1>−56−1
q<56
Answer: q<56

Solve for x -3(-3x-1) +2x+2=27

Zielflug [23.3K]

Answer:

$x=2$

Step-by-step explanation:

So we have the equation:

$-3(-3x-1)+2x+2=27$

First, distribute the -3:

$9x+3+2x+2=27$

Combine like terms:

$11x+5=27$

Subtract 5 from both sides:

$11x=22$

Divide both sides by 11:

$x=2$

So, the value of x is 2.

And we're done!

Approximately 10% of all people are left-handed. If 200 people are randomly selected, what is the expected number of left-handed

katrin [286]

Answer:

N(L) = 20

The expected number of left handed people is 20.

Step-by-step explanation:

Given;

Percentage of left handed people P(L) = 10%

Total number of selected people N(T) = 200

The Expected number of left handed people N(L) is;

N(L) = Total number of selected people × Percentage of left handed people/100%

N(L) = N(T) × P(L)/100%

Substituting the given values;

N(L) = 200 × 10%/100%

N(L) = 200 × 0.1

N(L) = 20

The expected number of left handed people is 20.

2. The variable expressions represent the angle measures of a triangle. Find the measure of each angle. Then classify the triang

Umnica [9.8K]

Answer:

Step-by-step explanation:

The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that

angle K + angle L + angle M = 180 degrees. Since

m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then

10x + 10 + 9x - 3 + 7x - 9 = 180

10x + 9x + 7x = 180 + 9 + 3 - 10

26x = 182

x = 182/26

x = 7

m angle K=(10x+10) = 10×7 + 10 = 80 degrees

m angle L=(9x-3) = 9×7 - 3 = 60 degrees

m angle M=(7x-9) = 7×7 - 9 = 40 degrees.

The triangle is an acute triangle because each angle is lesser than 90 degrees

The triangle is scalene triangle because non of the sides are equal.
