Az + 17 = -4z - b What is z?

Mathematics
1 answer:
Sholpan [36]3 years ago
8 0

To solve Az + 17 = -4z - b for z, we begin by combining like terms. We get:

Az + 4z = -b - 17, or z(A+4) = -(b+17).

Dividing both sides by (A+4), we get:

-(b+17)

z = --------------

A+4

10-d = -34-5d solve this equation
algol13
<h3><u>Explanation</u></h3>
  • Given the equation.

10 - d =  - 34 - 5d

  • Solve the equation for d-term.

Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

10 + 34 =  - 5d + d \\ 44 =  - 4d \\  \frac{44}{ - 4}  = d \\  - 11 = d

  • Answer Check

Substitute d = -11 in the equation.

10 - ( - 11) =  - 34 - 5( - 11) \\ 10 + 11 =  - 34 + 55 \\ 21 = 21

The equation is true for d = -11.

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

<u>\large \boxed{d =  - 11}</u>

Two times a number added to another number is 25. Three times the first number minus the second number is 20. What are both numb
lawyer [7]

Answer:

the two number are 7 and 9

Step-by-step explanation:

2*x+y=25

3x-y = 20

add the two equations

2*x+y=25

3x-y = 20

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

5x = 45

divide by 5

5x/5 = 45/5

x = 9

lets find y

2x+y = 25

substitute x

2*9 +y =25

18+y =25

subtract 18 from both side

y = 25-18

y =7

Find the range. 4.7 6.3 5.4 3.2 4.9 3.1 –3.1 9.5 –9.5
WINSTONCH [101]

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19
