[(3+5)x2-5] x 3

Do the parentheses first.

[8 x 2 - 5] x 3

Then multiplication.

[16 - 5] x 3.

Now the brackets.

[11] x 3 = 33

If this helped you, please list me as brainliest!

The tape diagram represents an equation.​
Lena [83]

Answer:  w+1.3 = 2.7

Reason:

The smaller pieces (w and 1.3) combine to form the larger piece (2.7)

To find w, subtract 1.3 from both sides to get 1.4

1.4+1.3 = 2.7

24 points scored in 4 games; 48 points scored in 10 games... are they equivalent?
ch4aika [34]

Hello.

24 points scored in 4 games = 24 * 4.

24 * 4 = 96

48 points scored in 10 games = 48 * 10

48 * 10 = 480

<em>96≠480, they are not equivalent.</em>

The cost C (in dollars) of making n watches is represented by C=15n 85. How many watches are made when the cost is $385?
FromTheMoon [43]
We know that C is 385, so we can plug that in to get the equation 385=15n+85. To find the number of watches, we have to solve for n.
To do that we have to...

385=15n+85

First subtract both sides of the equal sign by 85 (because we need to do the opposite)

300=15n (because 85-85 is zero, so we eliminated that, and 385-85 is 300)

Now we divide both sides of the equal sign by 15 (again, opposites)

20=n (because 15n/15 leaves us with n since both 15s cancel out, and 300/15 is 20)

So the number of watches made were 20.

<span>I chose a box of cereal-------> rectangular prism
</span>see the attached figure

Part 1)<span>List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length: 20 cm
Width: 8 cm
Height: 32 cm

Part </span><span>2).
 Describe the shape of the cross-section when the box is cut parallel to the base

the shape of the </span>cross-section <span>would be a rectangle of dimensions
20 cm x 8 cm

Part 3)
</span><span>What is the surface area of the box? 
</span>
surface area=2*area of the base+perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm
height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is
2,112 cm²

Part 4)
<span>What is the surface area of the box if it is scaled up by a factor of 10?
</span>
we know that
surface area of the larger box=[scale factor]²*surface area original box

scale factor=10
surface area original box=2,112 cm²
so
surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is
211,200 cm²

Part 5) 
<span>What is the volume of the box?
</span>
volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³

the answer Part 5) is
5,120 cm³

Part 6) 
<span>What is the volume of the box if it is scaled down by a factor of 1/10

we know that
volume of the smaller box=[scale factor]</span>³*volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

the answer part 6) is
5.12 cm³
