What is the value of x for which (8-x)^2=x^2
Answer:
x = 4
Step-by-step explanation:
[tex] {x}^{2} = {(8 - x)}^{2} [/tex]
[tex] = > {x}^{2} = {x}^{2} - 16x + 64[/tex]
[tex] = > {x}^{2} - {x}^{2} + 16x = 64[/tex]
[tex] = > 16x = 64[/tex]
[tex] = > x = \frac{64}{16} = 4[/tex]
Step-by-step explanation:
(8 - x)² = x²
=> 8 - x = x or 8 - x = -x (rejected)
=> x = 4.

For the sequence an = 3 + 6 · (n − 1),
its first term is :
its second term is:
its third term is:
its fourth term is:
its fifth term is:
its common difference d=
[tex]a_n[/tex] is the n-th term in the sequence. So
• the first term (n = 1) is a₁ = 3 + 6•(1 - 1) = 3
• the second term (n = 2) is a₂ = 3 + 6•(2 - 1) = 9
• the third term (n = 3) is a₃ = 3 + 6•(3 - 1) = 15
• the fourth term (n = 4) is a₄ = 3 + 6•(4 - 1) = 21
• the fifth term (n = 5) is a₅ = 3 + 6•(5 - 1) = 27
The common difference between terms is what you get from subtracting consecutive terms in the sequence, or the number [tex]a_n-a_{n-1}[/tex]. Just by taking any two consecutive numbers from above, you have d = 6, since
9 - 3 = 6
15 - 9 = 6
and so on. More generally,
[tex]a_n-a_{n-1}=(3+6\cdot(n-1)) - (3+6\cdot(n-2))=6\cdot((n-1)-(n-2))=6[/tex]

Shady Rivers summer camp has 188 campers this week. If there are 22 campers to each cabin, what is the least number of cabins needed?
The least number of cabins needed for campers is 8.
Given that, Shady Rivers summer camp has 188 campers this week.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The least number of cabins needed = Total number of campers/Number of campers to each cabin
= 188/22
= 8.54
Therefore, the least number of cabins needed for campers is 8.

A study of a population of 1,500 moths revealed that 15 out of every 75 moths in the population have gray stripes on their wings. Based on the results of this study, how many moths in the population have gray stripes on their wings?
Answer: 300 moths
Step-by-step explanation:
Since 15 out of every 75 moths in the population have gray stripes on their wings, this means the fraction of moths that have gray stripes on their wings is 15/75 = 1/5.
Therefore, out of 1500 moths, the number of moths in the population that have gray stripes on their wings would be calculated as:
= 1/5 × 1500
= 300 moths
what error did the student make?? PLEASE HELP ME
Answer:
He did an error because he multiplied equation 2 wrongly.
The correct multiplication should have been:
-6x + 9y = 6 Multiply equation by 2 by 3
Step-by-step explanation:
Given the system of equations
3x-5y=4
-2x+3y=2
This is what student solved
6x - 10y = 8 Multiply equation 1 by 2
-6x + 3y = 6 Multiply equation by 2 by 3
_________
-7y = 14
y = -2
He did an error because he multiplied the equation 2 wrongly.
The correct multiplication should have been:
-6x + 9y = 6 Multiply equation by 2 by 3
NOW, HERE IS THE CORRECT VERSION
6x - 10y = 8 Multiply equation 1 by 2
-6x + 6y = 6 Multiply equation by 2 by 3
_________
-4y = 14
y = -2/7

how do you solve graphs and make an equation from a line on a graph?
Always start on the y-axis.
rise/run
First things first, you have to know your positives, negatives, zeros, and undefined.
To make an equation from the graph you have to know your formula.
y=mx+b
You do the rise first. The rise on the graph is 3. The run is 2. So, that'll make it 3/2. m=slope.
b=y-axis. b=1.
y=3/2x+1 (Example from the image)

Christie has a total of 15 pieces of fruit are bananas and apples worth $1.59 bananas are $.13 each and apples are seven cents each how many bananas and how many apples does she have
Answer:
a = apple
b = banana
a + b = 15 so a = 15 - b
0.07a + 0.13b = 1.59
substitute a = 15 - b into 0.07a + 0.13b = 1.59
0.07a + 0.13b = 1.59
0.07(15 - b) + 0.13b = 1.59
1.05 - 0.07b + 0.13b = 1.59
0.06b = 0.54
b = 0.54/0.06
b = 9
a = 15 - b
a = 15 - 9
a = 6
answer: 6 apples and 9 bananas

Corrine bought 8.4 pounds of almonds. She divided them into 30 snack-size bags. How many pounds are in each bag?
helphelphelp ASAPPPPP!!!!!
Answer:
0.28 pounds in each bag.
Step-by-step explanation:
There are 0.28 pounds in each snack-size bag.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings.
For example 4/2 = 2
We have been given that she bought 8.4 pounds of almonds. She divided them into 30 snack-size bags.
We have to determine the number of pounds in each bag.
The number of pounds in each bag = total quantity of almonds ÷ number of bags
The number of pounds in each bag = 8.4 pounds ÷ 30 bags
The number of pounds in each bag = 8.4/30
Apply the division operation, and we get
The number of pounds in each bag = 0.28 pounds
Thus, there are 0.28 pounds in each snack-size bag.

Which line appears to have an x-intercept of -3 and a intercept of 5?
The first graph shows the x-intercept of -3 and y - intercept of 5.
Option A is true.
What is Intercepts?
The points in which the graph crosses the two axis ( x and y axis) are called Intercepts.
Given that;
The x - intercepts = -3
And, The y - intercepts = 5
Since,
The x - intercepts = -3
That's mean the line cross at the point - 3 on x - axis.
And, The y - intercepts = 5
That's mean the line cross at the point 5 on y - axis.
Clearly, In graph first;
The graph of the line is crosses at the point on x - axis at the point -3 and y - axis at the point 5.
Therefore,
The first graph shows the x-intercept of -3 and y - intercept of 5.

8. Present age of Rahul and kiran are in the ratio
5:4. The ratio of their ages will be 6:5 after
5 years.Find kiran's present age.
20 years
25 years
30 years
15 years
Answer:
20 years
Step-by-step explanation:
Given the ratio of their ages = 5 : 4 = 5x : 4x ( x is a multiplier )
Then in 5 years
5x + 5 : 4x + 5 = 6 : 5 , that is
[tex]\frac{5x+5}{4x+5}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )
5(5x + 5) = 6(4x + 5) ← distribute parenthesis on both sides
25x + 25 = 24x + 30 ( subtract 24x from both sides )
x + 25 = 30 ( subtract 25 from both sides )
x = 5
Thus
Kiran's age is 4x = 4 × 5 = 20
