10x – 3 = 8x + 5
Answers
Answer:
x =4
Step-by-step explanation:
10x – 3 = 8x + 5
Subtract 8x from each side
10x-8x – 3 = 8x-8x + 5
2x-3 =5
Add 3 to each side
2x-3+3 =5+3
2x= 8
Divide by 2
2x/2 =8/2
x =4

11.) The sum of four consecutive even
integers is 68. Find the four consecutive
even integers. What is the 3rd integer
in the sequence?
Answers
Answer:
Four consecutive even integers are 14, 16, 18 and 20Third number in the sequence is 18
Step-by-step explanation:
Let N be the first even integer
Each consecutive integer is 2 away from the previous integer
Next consecutive integer = N + 2, next one = N+4 and the last one = N +6
Add these expressions together, set them equal to 68 to solve for N
==> N + (N +2) + (N +4) + (N + 6) = 68
==> N + N +2 + N +4 + N + 6 = 68
==> 4N + 12 = 68
==> 4N = 68-12
==> 4N = 56
N = 56/4 = 14
So the integers are 14, 16, 18 and 20
Third integer in the sequence is 18

Solve for x: 3x − 2 > 5x + 10. (5 points)
Question 9 options:
1)
x > 6
2)
x −6
Answers
Answer:
x < -6
Step-by-step explanation:
3x - 2 > 5x + 10
first step is to isolate x
3x -2 >5x +10
3x > 5x + 10 + 2
3x -5x > 10 + 2
now that we have 3x and -5x we can combine them
-2x > 10 + 2
now add 10 +2 =12
-2x > 12 (now divide by -2)
x < -6 (when we divide we flip the inequality sign)
3. Solve for x: (x-3)2 =16
Answers
Answer:

add 6 to both sides
2x -6 + 6 = 16 + 6
2x = 22
divide by 2
2x/2 = 22/2
x = 11

Answers
The shortest distance between n and p in units = (1 − a )2+ ( b+ 2)2.
The correct option is B.
Distance between two points:The length of line segment connecting any two points is known as their distance from one another. The length of a line segment connecting the two given coordinates can be used to calculate the distance between the points in coordinate geometry.
What is coordinate geometry used for?The study of geometry utilizing coordinate points is referred to as coordinate geometry (or analytic geometry). The distance between two points can be calculated using coordinate geometry, as can the areas of triangles in the Cartesian plane, the midpoints of lines, and more.
According to the given information:The expression that represents this same shortest distance between P and N in units is found to use the distance between two points to be:
[tex]d=\sqrt{(1-a)^2+(b+2)^2}[/tex]
The distance between two points, (x1,y1) and (x2,y2), is represented by:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
the distance between the points N(a, -2) and P(1,b) is:
[tex]\begin{aligned}&d=\sqrt{(1-a)^2+(b-(-2))^2} \\&d=\sqrt{(1-a)^2+(b+2)^2}\end{aligned}[/tex]
The shortest distance between n and p in units = (1 − a )2+ ( b+ 2)2.

Answers
300 + (200)r is the proper expression for sales if the number of units expected to be sold is uniformly distributed between 300 and 500. If r is a random number between 0 and 1.
What is a random number?
a random number is a number chosen by chance -- i.e., randomly, from a set of numbers. All the numbers in a specified distribution have equal probability of being chosen randomly.
Given that r is a random number between 0 and 1. it is uniformly distributed between 300 and 500 will be done by using the formula of 300+200r.
If r = 0, 300+200r will result in the output as 300
If r = 0.5, 300+200r will result in the output as 400
If r= 1, 300+200r will result in the output as 500
Hence ,the proper expression for sales is 300+200r

The required solution after three successive iterations is near x = 7/8. Option c is correct.
What is the equation?The equation is the values of two expressions that are equal. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here, we have,
Equation is -2x + 6 = -(2/3)^x + 5. Approximate the solution to the equation above using three iterations of successive approximation.
given that,
-2x + 6 = -(2/3)^x + 5
Arranging the equation
(2/3)^x - 2x + 1 = 0
Since the solution of the equation is when f(x) = 0 at near to x = 0.8
f(x) = (2/3)^x - 2x + 1
First iteration at x =0.8
f(0.8) = 0.123
It will go up more to get exact zero, so
Second iteration at x = 0.9
f(0.9) = -0.106
It seems that zero is near 0.9 so will go down
The third iteration at x = 0.87
f(0.87) = -0.037
Here , solution is much near to x = 0.87 or x =7/8.
Thus, the required solution after three successive iterations is near x = 7/8.
