-40-2(3m+1/2)=7m-2 what does m equal

Answers

Answer 1

Answer: [tex]m[/tex] = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2

Step 2: Simplify −40 − 6[tex]m[/tex] − 1 to −6[tex]m[/tex] − 41.

−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2

Step 3: Add 6[tex]m[/tex] to both sides.

−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]

Step 4: Simplify 7[tex]m[/tex] − 2 + 6[tex]m[/tex] to 13[tex]m[/tex] − 2.

−41 = 13[tex]m[/tex] − 2

Step 5: Add 2 to both sides

−41 + 2 = 13[tex]m[/tex]

Step 6: Simplify −41 + 2 to −39.

−39 = 13[tex]m[/tex]

Step 7: Divide both sides by 13.

−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]

Step 8: Simplify [tex]\frac{39}{13}[/tex] to 3.

−3 = m

Step 9: Switch sides.

[tex]m[/tex] = −3

~I hope I helped you! :)~

6x - 2 3x + 7 18. Identify the segment bisector of RS. Then find RS. (Section 1.3) M R S​

Answers

Answer:

m is 7

Step-by-step explanation:

The length of RS is 32.

Given,

M is the bisector of RS

RM = 6x - 2

MS = 3x + 7

We need to find RS.

What does it mean to be a bisector point in a line?

A bisector point in a line divides the line into two equal halves.

Example:

A_____B_____C

B = midpoint

AB = BC

AC = AB + BC

We have,

R_____M______S

RS = RM + MS

M = bisector

RM = MS

RM = 6x - 2

MS = 3x + 7

6x - 2 = 3x + 7

6x - 3x = 7 + 2

3x = 9

x = 9/3

x = 3

Now,

RS = RM + MS

RS = 6x - 2 + 3x + 7

RS = 9x + 5

RS = 9 x 3 + 5

RS = 27 + 5

RS = 32

Thus the length of RS is 32.

Jeff bought a bottle of water for $2. He also bought some hot dogs for $3 each. Jeff did not spend more than $14 on the hot dogs and the bottle of water. Which inequality can be used to find h, the number of hot dogs that Jeff could have bought? A.3h−2≤14 B.3h+2≤14 C.3h−2≥14 D.3h+2≥14

Answers

Answer:

D. 3h + 2 ≥ 14

Step-by-step explanation:

Cost of Bottle water = $2

Cost of Hot dogs = $3

Number of hot dogs bought = h

Total cost of hot dogs = price × quantity

= 3 * h

= 3h

Jeff did not spend more than $14

Total cost of bottle water and hot dogs

3h + 2 ≥14

The correct answer is D

D. 3h + 2 ≥ 14

Here are two similar rectangles.
4 cm
4.8 cm
7 cm
Work out the area of the larger rectangle.

Answers

Answer:

[tex]40.32cm^{2}[/tex]

Step-by-step explanation

4*1.2=4.8

7*1.2=8.4

8.4*4.8=40.32

A rectangle is a two-dimensional shape where the length and width are different.

The length and width of the larger rectangle are 4.8 cm and 8.4 cm.

The area of the larger rectangle is 40.32 cm².

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Two similar rectangles:

Smaller rectangles:

Length = 4 cm

Width = 7 cm

Larger rectangles:

Length = 4.8 cm

We need to find the width of the larger rectangle.

Since the two rectangles are similar.

4 cm = 4.8 cm

Multiply 7/4 on both sides.

7/4 x 4cm = 7/4 x 4.8 cm

7 cm = 8.4 cm

Now,

Larger rectangle:

Length = 4.8 cm

Width = 8.4 cm

Now,

The area of the larger rectangle:

Area = Length x width

Area = 4.8 x 8.4

Area = 40.32 cm²

Thus,

The area of the larger rectangle is 40.32 cm².

#SPJ5

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables

Answers

Answer:

5.5

Step-by-step explanation:

Add each side of the triangle.

3z+z+1+4z-3 = 8z - 2

8z - 2 is equivalent to the  perimeter.

Since you know the perimeter is 38 units, you can set 8z-2 to 38.

8z-2 = 38

Solve for z. Subtract 2 from each side.

8z = 36

Divide each side by 8.

z = 4.5

Now solve for side WX.

WX = z + 1

WX = 4.5 + 1

WX = 5.5

Solve for x in the following triangle.​

Answers

Answer:

x = 12

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

8 + 6x is an exterior angle of the triangle, thus

8 + 6x = 30 + 4x + 2 = 4x + 32 ( subtract 4x from both sides )

8 + 2x = 32 ( subtract 8 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12
