Answer:

<u>Dan has 16 marbles.</u>

Step-by-step explanation:

We know that Frank has 15 marbles and that the three people combined have 63 marbles, therefore the first step is to substrack the 15 marbles of Frank out of the total.

63-15=48

Now, Dan and Ellie have 48 marbles between each other but we know that Ellie has twice the amount that Dan has. So we first need to divide 48 by three

48/3=16

If there would be three people instead of two (Dan and Ellie) then each of them would have 16 marbles. but in this case, Ellie has twice the amount, therefore Ellie has 32 (16x2) and Dan has the remaining 16 marbles

Dan= 16 marbles

Ellie=32 marbles

Frank=15 marbles

Total amount= 16+32+15=63.

Solve the inequality x divided by 6 is less than or equal to 3
Alja [10]
Your inequality looks like this:
\frac{x}{6}  \leq 3
To get rid of the /6, you need to multiply by 6 as the opposite operation cancels it out. So, all you need to do is multiply both sides by 6 to isolate x. 
Therefore:
x \leq 18

The perimeter of a rectangle is 34 units. Its width is 6.5 point, 5 units.
12345 [234]
<h3><u>Question:</u></h3>

The perimeter of a rectangle is 34 units. Its width W is 6.5 units.

Write an equation to represent the perimeter in terms of the length L, and find the value of L

<h3><u>Answer:</u></h3>

The length of rectangle is 10.5 units

<h3><u>Solution:</u></h3>

Given that,

Perimeter of rectangle = 34 units

Width of rectangle = 6.5 units

Let "L" be the length of rectangle

<em><u>The perimeter of rectangle is given by formula:</u></em>

Perimeter = 2(length + width)

<em><u>Substituting the values we get,</u></em>

34 = 2(L + 6.5)

Thus the equation is found

<em><u>Solve for "L"</u></em>

L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5

Thus length of rectangle is 10.5 units

Its only one math question show right steps then get brainliest and right answer ofc
valkas [14]

Step-by-step explanation:

equation.

2(m+10)=4(m−15)

(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)

2m+20=4m+−60

2m+20=4m−60

Step 2: Subtract 4m from both sides.

2m+20−4m=4m−60−4m

−2m+20=−60

Step 3: Subtract 20 from both sides.

−2m+20−20=−60−20

−2m=−80

Step 4: Divide both sides by -2.

−2m−/2=−80/−2

m=40
