Solve for m. –5 − 5m = –6m
m= _

Answers

Answer:

M = 5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−5−5m=−6m

−5+−5m=−6m

−5m−5=−6m

Step 2: Add 6m to both sides.

−5m−5+6m=−6m+6m

m−5=0

Step 3: Add 5 to both sides.

m−5+5=0+5

m=5

Mr. Smith plans to build a 3-foot-wide walkway

surface of the walkway?

A. 171

B. 324

360

396

720

Answers

Answer:

360

Step-by-step explanation:

The area of the top surface of rectangular cabin walkway is given by the equation A = 360 feet²

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangular cabin be represented as A

Now , the initial length of the cabin = 30 feet

The initial width of the cabin = 24 feet

And , Mr. Smith plans to build a 3-foot-wide walkway around the outside of the cabin

So , the increased length of the rectangular cabin = 30 + 6 = 36 feet

The increased width of the rectangular cabin = 24 + 6 = 30 feet

Now , Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of rectangular cabin A = 36 x 30

Area of rectangular cabin A = 1080 feet²

Now , the area of the cabin before increment of sides = 24 x 30

The area of the cabin before increment of sides = 720 feet²

So , the area of the walkway = 1080 - 720 = 360 feet²

Area of rectangular cabin walkway A = 360 feet²

Hence , the area of the rectangular cabin walkway is 360 feet²

Simplify the following expression.

A. 51x + 4y
B. 22x + 46y
C. 22x + 42y
D. 51x+ 42y​

Answers

Answer:

The answer would be D.

Step-by-step explanation:

All you have to do is combine like terms.

Pretend that the parenthesis aren't there. 13x + 9y + 38x + 33y.

When you combine like terms, you add or subtract the terms that have the same variable attached.

13x + 38x = 51x.

9y + 33y = 42y

51x + 42y.

What is the next term of the geometric sequence?
7, 21, 63

Answers

First find the common ratio of this geometric sequence.

We will use [tex]r = \frac{a2 }{a1 }[/tex].

The second term is 21 and the first term is 7.

So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.

So, we take the last term in our geometric sequence

and multiply it by the common ratio we just found.

So we have 63 · 3 which is 189.

So the next term in this geometric sequence is 189.

Answer: 189
Explanation:
The rule for this sequence is to multiply by 3.
7•3 = 21
21•3= 63
So the next term would be 189 because,
63•3=189

Answers

Answer:

Line : y = ax + b, passes (0, 3) and (2, -3)

=> b = 3

=> 2a + b = -3

=> a = -6/2 = -3

=> Slope a = -3

=> Option D is correct

Hope this helps!

:)

Answer:

D is the answer

Step-by-step explanation:

Slope = rise / run

Slope = y2-y1 / x2-x1

Where coordinates are

(0,3),(2,-3)

So x1=0,y1=3 , x2=2 , y2= -3

Slope= -3-3/ 2-0

Slope = -6/2

Slope = -3

Answers

Answer:

The representative sample contained more girls than boys.

Step-by-step explanation:

A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.

Then use the triangle angle sum theorem and set the equation to 180.

55+55+x=180
110+x=180
x=70

The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
