-6(-1 + 2c)
6(-n + 7)
9(5 + 3c)

Answers

Answer 1

Step-by-step explanation:

Do the steps that I did on Problem A for each!!!!

A:-3(4-3p)

a=-3, b=4, c=3p

Apply the distributive law:

[tex]-3*4-(-3)*3p[/tex]

Add minus - plus rules:

[tex]-3*4+3*3p[/tex]

Simplify:

=[tex]-12+9p[/tex]

B:-3(7-6u)

a=-3, b=7, c=6u

=-3*7+3*6u

Simplify;

=[tex]-21+18u[/tex]

C:-6(-1+2c)

a=-6, b=-1, c=2c

=-6(-1)+(-6)*2c

=6*1-6*2c

Simplify:

=[tex]6-12c[/tex]

D:6(-n+7)

a=6,b=-n,c=7

=6(-n)+6*7

=-6n+6*7

Simplify:

=--6n+42

E;9(5+3c)

a=9,b=5,c=3c

=9*5+9*3c

Simplify:

=45+27c

Find the values of x and y.
A. x = 42, y = 26.3
B. x = 47, y = 30
C. x = 42, y = 30
D. x = 47, y = 26.3

Answers

Answer:

C

Step-by-step explanation:

2x + 1 = 85 (Alternate Interior Angles Theorem)

2x = 84

x = 42

(3y + 5) + (2x + 1) = 180 (Linear Pair Theorem)

3y + 5 + (85) = 180

3y + 5 = 95

3y = 90

y = 30

Answer:

x = 42, y = 30

Step-by-step explanation:

Alternate angles are equal so

85 = 2x + 1

2x = 84

x = 42°

Linear pair

(3y + 5) + (2x + 1) = 180

3y + 5 + 85 = 180

3y = 90

y = 30°

So I think the answer is x = 42° and y = 30°.

Hope it helps.

Answer:

Total area = 28 ft²

Step-by-step explanation:

The shape is composed of 2 rectangles and 1 triangle.

✔️Area of rectangle 1 (the larger rectangle):

Length = 5 ft

Width = 4 ft

Area of rectangle 1 = L * W = 5*4 = 20 ft²

✔️Area of rectangle 2 (the smaller rectangle):

Length = 10 ft - 5 ft = 5 ft

Width = 1 ft

Area of rectangle 2 = L * W = 5*1 = 5 ft²

✔️Area of triangle:

Base = 2 ft

Height = 3 ft

Area of triangle = ½*base*height

Area of triangle = ½*2*3 = 3 ft²

✅Total area of the shape = 20 + 5 + 3 = 28 ft²

5 points Two lines are represented by equations: 10x - 15y = 21 and y = kx + 5. What value of k will make lines perpendicular?​

Answers

Answer:

Step-by-step explanation:

10x - 15y = 21

15y = 10x - 21

slope of line is ⅔

slope of any perpendicular to line is -3/2

y = kx + k

slope of line is k

k = -3/2

570 milliliters equal how many centiliters

Answers

Answer:

It equals 57 centiliters.

Step-by-step explanation:

The reason why is because any number that has a 0 is subtracted to less without the 0, so for example lets say 1,680 milliliters equal how many centiliters the answer would be 1,680. Take out the 0 out of any number u add to if you want to know the centiliter

Answer: 57

Step-by-step explanation:

We can set up a proportion to solve for the number of centiliters.

1ml/ 570ml = 0.1 centiliter/ xcentiliter

Now, we cross multiply to solve for our unknown x:

x centiliter ≈ 570 ml / 1 ml * 0.1 centiliter → x centiliter ≈ 57.0 centiliter

Conclusion:

570ml ≈ 57.0 centiliter

For a certain value of k, the system

x + y + 3z = 10,
-4x + 3y + 5z = 7,
kx + z = 3
has no solutions. What is this value of k?

Answers

Answer:

k = 7/4

Step-by-step explanation:

Given system:

x + y + 3z = 10, -4x + 3y + 5z = 7, kx + z = 3

Substitute z in the first two equations with z = 3 - kx:

x + y + 3(3 - kx) = 10 ⇒ (1 - 3k)x + y = 1 ⇒ y = (3k - 1)x + 1-4x + 3y +5(3 - kx) = 7 ⇒ -(4 + 5k)x + 3y = -8 ⇒ y = 1/3(5k + 4) - 8

In order the two equations above not to have a solution, the lines should be parallel. Parallel lines have equal slopes.

Solve the following equation for k:

3k - 1 = 1/3(5k + 4)9k - 3 = 5k + 44k = 7k = 7/4

The stock market gained 45 points on Tuesday and lost 32 points on Wednesday. It had closed on Monday at 2760 points. Where did the market close on Wednesday?

Answers

Answer:

The market closed with a rating of 2773 points on Wednesday.

Step-by-step explanation:

Lets start with what we know:

Monday at close it had a rating of 2760 points.

Tuesday it gained 45 points.

Wednesday it had lost 32 points.

Once written out it becomes less intimidating to answer.

Monday + Tuesday + Wednesday = Answer

2760 + 45 - 32

= 2805 - 32

= 2773

2760(market on monday) + 45(how much gained on tuesday) = 2805 (points on tuesday)

2805(point on tuesday) - 32(how much lost on wednesday) = 2773 (points on wednesday/the answer)
