Write and evaluate the expression. Then, select the correct answer.

Law Incorporation [45]

Answer:

Step-by-step explanation: So we need to write and solve an equation to solve for m, which is 12. Simply plug in 12 for m in the equation.

Step 1: 2-x/4+10

Step 2: 2-12/4+10

Step 3: 2-3+10

Step 4: -1+10=9

Plug 12 in for x

12 divided by 4 is 3 and 2-3 is -1

-1 + 10 is 9 -1 + 10 is 9

Can anyone explain the method for algebraic fraction? We have to do it for maths, and i'm really struggling with it. Here is an

riadik2000 [5.3K]

Answer:

x=3

Step-by-step explanation:

The approach is not very different from regular fractions.

You have to get to a common denominator to be able to add them.

10 is a good denominator (multiply the denominators).

multiply the first term by 5, and the second one by 2:

$\frac{5 \cdot (x+1)}{5 \cdot 2} + \frac{2 \cdot (x+2)}{2 \cdot 5} = 3$

$\frac{5x+5 + 2x+4}{10} = 3$

$\frac{7x+9}{10} = 3$

7x + 9 = 30

7x = 30 - 9

x = 3

let me know if you need more details on one of the steps

A company makes storage containers with sheet steel walls. The containers are shaped like rectangular prisms, as shown below. If

Alecsey [184]

Answer:

$2360m^2$ of sheet steel are needed

Step-by-step explanation:

Given

The missing dimensions are:

$Length = 5m$

$Width = 6m$

$Height = 8m$

$n=10$ --- number of containers

Required

The surface area of all containers

First, we calculate the surface area (A) of 1 container

$A=2*(Length * Width + Length * Height + Width * Height)$

$A=2*(5m* 6m+ 5m* 8m+ 6m * 8m)$

$A=2*(30m^2 + 40m^2 + 48m^2)$

$A=2*(118m^2)$

$A=236m^2$

The surface area of 10 is:

$Area = 10 * A$

$Area = 10 * 236m^2$

$Area = 2360m^2$
