Answer:

x=-10

Step-by-step explanation:

2(x+3)=x-4

2*x+2*3=x-4

2x+6=x-4

2x-x=-4-6

x=-10

Answer:

$x = - 10$

Step-by-step explanation:

Let's solve:

$2(x+3)=x−4$

Step 1: Simplify both sides of the equation.

$2(x+3)=x−4 \\ (2)(x)+(2)(3)=x+−4(Distribute) \\ 2x+6=x+−4 \\ 2x+6=x−4$

Step 2: Subtract x from both sides.

$2x+6−x=x−4−x \\ x+6=−4$

Step 3: Subtract 6 from both sides.

$x+6−6=−4−6 \\ x=−10$

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

c) 0.01

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

To Write percentage in decimal or fraction we divide it by 100

therefore,

$\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}$

Half of 0.02 = $\sf\frac{1}{\cancel2} \times\cancel{0.02}$

$\implies\boxed {0.01}$

Here is another one I need help with

aksik [14]

Answer:

Step-by-step explanation:

Surface area of objects with flat surfaces like this is simply the area of each surface added together, so let's get to work.

Both have 6 faces, so we will be adding six values together for each.

Container A:

Hopefully you can imagine the six different faces. It's kinda like a cereal box.

The front and back of a cereal box have the same area, as do the two sides and the top and bottom, so that makes it a little easier.

Front and Back: 28 * 36 = 1008

Sides: 36*6 = 216

Top and Bottom: 6*28 = 168

Let me know if you don't understand how I did any of that. Anyway, since there is a matching face for each we add them all together twice.

1008*2 + 216*2 + 168*2 = 2784 in^2

Container B has a similar setup, I won't write out everything like I did unless you want me to work it out with you.

2(16*12+16*22+22*12) = 1616 in^2

So since Container A has a surface area of 2784 and Container B has a surface area of 1616 it's obvious container A has a larger surface area

Arun has apples and oranges in the ratio 5:3. Convert the ratio of apples and oranges to the total fruits in fraction form and p

Korvikt [17]

Answer:

Apples: 5/8 or 62.5%

Oranges: 3/8 or 37.5%

Step-by-step explanation:

You would figure this out because Aran has 5 apples and 3 oranges and if you’re trying to find the percentage to total number of fruits you have, it would be 5 apples/ 8 fruits and 3 oranges/ 8 fruits.

Hope this helped :)
