What is the solution to this equation?
x + 12 = -5
O A. x= -17
B. X= -7
O c. x= 17
O D. x = 7

Answers

Answer 1

Answer:

x=-17

Step-by-step explanation:

Original Equation;

x+12=-5

The 12 will cross the equal sign so it will become -12. So it's going to be;

x=-5-12

There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;

x=-17

This is the final answer!!!

A turkey cost $1.05 per pound. There are going to be 15 people at the Thanksgiving dinner. Plan for each person to eat two, 3/8 pound servings for turkey. It takes 12 minutes per pound to cook a turkey and dinner is at 3:00 pm. How many minutes will it take to cook the turkey?

Answers

Answer:

It will take 135 minutes or 2 hours and 15 minutes

Step-by-step explanation:

What we need here is to get the total

amount in pounds of turkey to be cooked

each person eats 3/8 pound servings

Total pound per person would be 3/8 * 2 = 3/4 pound servings

From what we have, there are 15 people at the dinner,

The total pounds to cook will be

15 * 3/4 = 45/4 pounds

Per pound of turkey, it takes 12 minutes

For 45/4 pounds, it will take

45/4 * 12 = 135 minutes

Let us convert this to hours

That will be 2 hours and 15 minutes

1. Use at least 2-3 sentences to explain how to find the measure of exterior angle of a triangle if you know the two remote interior angles.



2.Use at least 2-3 sentences to explain how to find the measure of an interior angle of a triangle when you are given the other two angle measures.

Answers

Answer:

Step-by-step explanation:

1). By definition of an exterior angle of a triangle,

  Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.

  From the figure attached,

  m∠4 = m∠1 + m∠2

2). Property of a triangle states that " sum of interior angles of a triangle is 180°"

   Therefore, m∠1 + m∠2 + m∠3 = 180°

The answers choices are -2, -1/2, 1/2, and 2.

A company announces that it will be giving $4,200 of its profits to charity. If the company profits 28,000 what percent will the company give to charity

Answers

Given:

Company profits = $28,000

Charity = $4200

To find:

The percent that will the company give to charity.

Solution:

We have,

Company profits = $28,000

Charity = $4200

Now,

[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]

[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]

[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]

[tex]Charity\%=15\%[/tex]

Therefore, the company will give 15% of its profit to charity.

What is the y-intercept of the line that contains the point (3, –2) and is perpendicular to the line y = – 2/5 x + 3/5?

Answers

Y = 5/2x because the A value need to be the opposite reciprocal for a perpendicular line you then plug the point you are given into our new EQ which equals -2=(5/2)(3) + b (solving for b) and you get b = -9.5 so your new equation is y = 5/2x - 9.5 making your Y int -9.5

Finding angle measures using triangles

Answers

Because HI and JK are parallel, that makes their angles congruent. So angle K equals angle I
So the interior angles of a triangle add up to 180°
So, Angle I + angle H + angle x =180°
60°+56°+x°=180°
116°+x°=180°
X=180-116
X=64°

There are 4 boys and 2 girls from the seventh grade and 3 boys and 5 girls from the eighth grade in the math club. The math club sponsor will randomly pick one student from each grade level to represent the team.

What is the probability that both will be girls?

Answers

Answer:

5/24 or 20.8%

Step-by-step explanation:

 

Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2

 

Probability that the 8th grader is a boy = 5/(5+7) = 5/12

 

Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
