What is the value of x in the linear equation below? 4+3x-ax=9-7x+bx

Mathematics
1 answer:
Furkat [3]3 years ago
7 0

Answer:

x = 5/(10 - a - b)

Step-by-step explanation:

Solve for x:

4 + 3 x - a x = 9 - 7 x + b x

Collect in terms of x:

x (3 - a) + 4 = 9 - 7 x + b x

Collect in terms of x:

x (3 - a) + 4 = x (b - 7) + 9

Subtract (b - 7) x + 4 from both sides:

x (10 - a - b) = 5

Divide both sides by 10 - a - b:

Answer:  x = 5/(10 - a - b)

Find the surface area of the composite figure​
Gnoma [55]

Answer:

=280 in^2

Step-by-step explanation:

----------------------------------------

Let's find the surface area of the pink rectangular prism first.

2*10=20+20=40

4*10=40+40=80

4*2=8+8=16

40+80+16=136

The surface area for the pink rectangular prism is 136 in^2.

-------------------->>>>>

Now, let's find the surface area of the green rectangular prism.

4*7=28+28=56

4*7=28+28=56

4*4=16+16=32

56+56+32=144

The surface area for the green rectangular prism is 144 in^2.

-------------------->>>>>

Now let's add the surface area of both rectangular prisms to find the surface area of the composite figure.

136+144=

=280 in^2

----------------------------------------

Hope this is helpful.

An assembly line with 17 tasks is to be balanced. The longest task is 2.4 minutes, and the total time for all tasks is 18 minute
Maurinko [17]

Answer:

Minimum cycle time = time for longest task = 2.4 minutes

Maximum cycle time = sum of the times to complete all the tasks = 18 minutes

Step-by-step explanation:

For the minimum cycle time, the reasoning is that all the tasks can be done simultaneously, at some during the assembling task. Hence, minimum time to complete one cycle is the time it takes to complete task that takes the longest time to complete.

For the maximum cycle time, the reasoning here is that each task is done after the completion of the previous task. The total time taken to finish the task will then be the sum of the time taken to complete each task. This usually is at the beginning of operations.

$290, 12.5%, 6 months
Veronika [31]
The information shown here only shows a principal sum, a rate of interest and a period or time. There is no question as to what is needed. But suppose the need is for simple interest, then we calculate using the given information and the formula: I = PRT where I is simple interest, P is the principal, R is the rate per year, and T is time P = 290, T is 6 months which is 0.5 years, R = 12.5 % which is written as 0.125 in decimal fraction. I = 290 × 0.125 x 0.5 → I = 18.125 Therefore after 6 months , the interest earned will be 18. 125 dollars
