Is 4d + (15 + 3d) equivalent to (4d + 15) + 3d ?

Answers

Answer 1

Answer:

Yes it is

Step-by-step explanation:

4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).

Answer 2
Answer:[tex]\boxed{\boxed{\sf{Yes,~7d+15=7d+15}}}[/tex]Solution Steps:

______________________________

1.) Solve [tex]\bold{4d+(15+3d)}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]2.) Solve [tex]\bold{(4d+15)+3d}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]

3.) Compare:[tex]7d+15=7d+15[/tex]

So your answer [tex]\bold{7d+15=7d+15}[/tex].

Answer:

It 12

Step-by-step explanation:

This is because the scale factor between the triangles is 1.75, so I divide 21 by 1.75 and got 12

Hope this helped

We first have to find 2 pairs of sides that proportional.

35/20=42/24=7/4

and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.

21/b=7/4

84=7b

b=12

Done!

Hope this helped, any questions about this just ask in the comments and I will answer.

3w - 11 = 25
can someone answer this plz

Answers

Answer:

w = 12

Step-by-step explanation:

3w = 11 + 25

3w = 36

w = 12

Hope that helps!

if you’re solving for W, the answer would be 12.

you subtract 11 from both sides leaving you with 3w=36, then you would divide by 3 on each side to get the w alone, leaving you with w=12

Solve the system of equations.
- 5y + 8x = -18
5y + 2x = 58
х=
y =

Answers

Answer:

x = 4 and y = 10

Step-by-step explanation:

-5y + 8x = -18

5y + 2x = 58

First you will want to get rid of y from both equations, so you add both equations together.

You will get 10x = 40, then subtract 10 from both sides and you get x = 4.

Now substitute x as 4 in any of the equations to get y.

-5y + 32 = -18

-5y = -50

y= 10

Answer:

x = 4

y = 10

6x + y = -1
y=-3x - 4

Answers

Answer:

x = 1, y = 7

Step-by-step explanation:

If y = -3x - 4, then

6x -3x -4 = 1

3x - 4 =-1

3x = 3

x = 1

If x = 1, then

y = -3*1 -4 = -3 -4 = -7

This hull enables them to float on the water very easily. Two small floats underneath its wings keep the flying boat stable in rough water. These seaplanes are usually larger and more stable on water than floatplanes are. A floatplane is a seaplane that has two long floats, called pontoons, under the fuselage. This is the only part of the plane that touches the water. Unlike flying boats, floatplanes often come in a wide variety of sizes. An amphibious vehicle can be either a flying boat or a floatplane with wheels. This allows the aircraft to land on both land and water.Which BEST describes the purpose of the paragraph?A.to explain how seaplanes are usedB.to encourage people to use seaplanesC.to list all of the types of seaplanesD.to describe the different parts of seaplanes what is the work done when a 400.n force is use to lift a 400.n object 3.5 meters strait up what is the molar mass of Br2 in grams Find the value of x.ABCD EFGH During operations outside declared hostilities, you may delay contact with local authorities.
