256b+17=90Solve for zzz.
Assume the equation has a solution for zzz.
-p\cdot(d+z) = -2z+59−p⋅(d+z)=−2z+59
The solution to the given algebraic equation is [tex]\mathbf{z = \dfrac{59+pd}{(p+2)}}[/tex]
Solving algebraic equations:Algebraic equations are mathematical expressions with variables, coefficients, and arithmetic operations. To solve algebraic expressions with two or more variables, the required variable to be solved must be the subject of the formula:
From the given information, we have:
[tex]\mathbf{-p\cdot(d+z) = -2z+59}[/tex]
So, the first step in solving this algebraic is to open the bracket.-pd +pz = -2z + 59
Collect like termspz + 2z = 59 + pd
Factorize the left-hand side of the equationz(p+2) = 59 + pd
Make (z) the subject of the formula:[tex]\mathbf{z = \dfrac{59+pd}{(p+2)}}[/tex]

Answer:
$6400 at 13%, $3600 at 10.5%82 hot dogs and 91 hamburgersStep-by-step explanation:
These are variations of a "mixture problem." A reasonable approach to the solution is to choose a variable to represent the quantity of the item contributing most to the mix. Then the quantity of the other item is the difference from the total quantity and the variable value. The equation you write will add up the values of the different quantities to get the total value.
__
1.Let x represent the amount invested at 13%. Then 10000-x is the amount invested at 10.5%, and the total interest earned is ...
0.13x +0.105(10000 -x) = 1210
0.025x +1050 = 1210 . . . . . eliminate parentheses
0.025x = 160 . . . . . . . . . subtract the constant on the left
x = 6400 . . . . . . . . . . divide by the coefficient of the variable
10000 -x = 3600
Anthony invested $6400 at 13% and $3600 at 10.5%.

2.Let x represent the number of burgers sold. Then the number of hot dogs sold is 173-x, and the total revenue is ...
3x +2(173 -x) = 437
x +346 = 437 . . . . . . . . . eliminate parentheses
x = 91 . . . . . . . . . . . . subtract the constant on the left
173 -x = 82
82 hot dogs and 91 hamburgers were sold.

Additional comment
You can solve these by writing two equations in two unknowns. You would let the variables represent the quantities of the two contributors. You would have one equation for the total quantity, and another equation for the total value.
These equations can be solved in any of the usual ways. If you solve by "substitution," where you substitute for the quantity of lower value, the equation you have as a result will match the equation described above.
The reason for keeping the variable representing the larger contributor is that its coefficient ends up positive as the solution progresses. That tends to make the arithmetic a little simpler and to reduce errors.
Hence, write down the equation with y as the subject (in terms of x). The value of m and q must be indicated.
Discuss whether it is possible that any devices are produced if the production cost is R 0,00
It is required that the production cost must be less than R 123 505. Determine the possible number of devices that will be produced. Show your solution graphically. Use interval notation and indicate the restriction on the number type of your answer. Interpret your answer.
The production cost is an illustration of a quadratic function

How to determine the equationFrom the complete question, we have the following parameters:
Computing components (a)Number of devices (x),Labor (b)Savings on reusable material (c)Using the instructions in the complete question, the equation of the production cost would be:
[tex]y = ax^2 + bx -c[/tex]
Hence, the production cost is [tex]y = ax^2 + bx - c[/tex]

In a triangle, the 3 angles add up to 180 degrees
=> Value of x = 180 - 62 - 15 = 103
y is supplementary to x (y + x = 180), so the value of y = 180 - 103 = 77
z = 180 - 60 - 77 = 43

How do I solve one step inequality’s
Answer:
[tex]x < -20[/tex]
Step-by-step explanation:
Given the following question:
[tex]x+8 < -12[/tex]
In order to solve one step inequalities, we solve how we would normally solve a one-step equation and then graph the answer on a number line.
[tex]x+8 < -12[/tex]
[tex]8-8=0[/tex]
[tex]-12-8=-20[/tex]
[tex]x < -20[/tex]
Now to graph the inequality on a number line, keep a few things in mind:
. x is less than -20 which means the line would go the opposite way of the negative 20.
. < is a greater than sign, not a greater than or equal sign (≤) so the number line will have a open point.
. The number line will have a point on -20.
Hope this helps.

How many more mins must he practice on the weekend to meet his goal??
Answer:
42 minutes
Step-by-step explanation:
70% x T = 98
7T/10 = 98
7T = 980
T = 140 mins
140 - 98
= 42 minutes
Answer: 42 mins
Step-by-step explanation: 70% / 7 x 3 = 98 / 7 x 3 = 14 x 3 = 42 minsDivide 70% by 7 to find 10%. Subtract 70 from 100 equals 30, so multiply 10 by 3 to find the remaining 30%.

The number of particles the compound consists of is 7.65 × 10²⁴.
It is given that
Number of moles n = 12.7
As we know the formula for the number of particles:
N=n× Nₐ
Where Nₐ is Avogadro's Number, n is the number of moles.
What is Avogadro's Number?Avogadro's Number is the number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10²³.
So, the number of particles:
N= 12.7 × 6.02214076 × 10²³.
N=7.65 × 10²⁴
Therefore, the number of particles the compound consists of is 7.65 × 10²⁴.

3.) MULTIPLE CHOICE: In 1983 a locally-owned car company sold 2,673 cars. In 2006, the car sales
rose to 4,194. What was the average rate of change for the total number of cars sold?
B.) approximately 15 cars per year
A.)3,434 cars per year
D.) 1,521 cars per year
C.) approximately 66 cars per year
Answer:
C) approximately 66 cars per year
Step-by-step explanation:
From 1983 to 2006, that is 2006 - 1983 = 23 (years).
The car sales rose from 2673 to 4194, that is 4194 - 2673 = 1521 (cars)
So the average rate of change is : 1521 : 23 = approx. 66 cars per year

Xavier needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4. 5 hours and charged him $155 for parts. The total was $357. 50. Write and solve an equation which can be used to determine xx, the cost of the labor per hour. ?
Answer:
The cost is $45 per hour.
Step-by-step explanation:
(h = hours)
1. The equation is 4.5h + 155 = 357.5.
2. Subtract 155 from both sides of the equal sign. The equation is 4.5h = 202.5.
3. Divide both sides by 4.5. The answer is h = 45.
