The sum of two numbers is 100, The difference between the two numbers is 95
workout the two numbers
Answer:
Let the numbers be x and y
x+y=100
x-y=95
taking x-y=95
x=95+y
x+y=100
95 + y +y = 100
2y=100-95
y=5/2
y=2.5
x=95+y
x=95+2.5
x= 97.5
Hope it helps...............
The two numbers are 97.5 and 2.5.
What is Addition and Subtraction?Subtraction is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Let x and y be the two numbers.
The sum is 100 and the difference is 95.
x + y = 100 ⇒ x = 100 - y
x - y = 95
Substituting x = 100 - y in the second equation,
100 - y - y = 95
100 - 2y = 95
2y = 100 - 95
2y = 5
y = 5/2 = 2.5
x = 100 - y = 100 - 2.5 = 97.5
Hence the numbers are 97.5 and 2.5.

If TRAP is an isosceles trapezoid, what is the value of x?
(5x +9)"
R
A. 9
B. 25
C. 18
D. 23
E. 19
F. Cannot be determined
Answer: 19, I had to get the question wrong :/
The value of x is 19
How to determine the value of x?From the question we understand that TRAP is an isosceles trapezoid
This means that the adjacent angles add up to 180 degrees.
So, we have:
5x + 9 + 4x = 180
Evaluate the like terms
9x = 171
Divide both sides by 9
x = 19
Hence, the value of x is 19

Step-by-step explanation:
Your cell phone plan is basic and costs $45 each month. You also must pay $0.10 per minute for long distance calls. How much would your month bill be if you had 45 long distance minutes? *
Given:
Basic cost = $45
Cost of long distance calls = $0.10 per minute
To find:
The total cost if you had 45 long distance minutes.
Solution:
Let the total cost be y for x minutes long distance calls.
Cost of long distance calls for one minute = $0.10
Cost of long distance calls for x minute = $0.10x
Total cost = Basic cost + Cost of long distance calls for x minute
[tex]y=45+0.10x[/tex]
Substitute x=45, to find the total cost if you had 45 long distance minutes.
[tex]y=45+0.10(45)[/tex]
[tex]y=45+4.5[/tex]
[tex]y=49.5[/tex]
Therefore, the total cost if you had 45 long distance minutes is $49.5.
Solve by finding square roots
4 (x-1)^2=96
Answer:
2√6 + 1
Step-by-step explanation:
Given expression:
4(x-1)² = 96
Solving by square root;
Square root both sides;
[tex]\sqrt{4(x-1)^{2} }[/tex] = √96
√4(x-1)² = √6x16
√4(x-1)² = 4√6
2(x-1) = 4√6
Divide both sides by 2;
x-1 = 2√6
Add 1 to both sides;
x = 2√6 + 1

What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
Fraction: -5 1/2
Now, converting it to the decimal
= -11/2
= -5.5
now, rounding off to whole -5.5 will lie between -5 and -6.
Hence, the whole number round off for - 1/2 is -6.

This week, 957 people went to the beach. Last week, 1,207 people went to the beach. The number of people who went to the beach fell by what percent? Use pencil and paper. Explain how you know whether the answer is greater than or less than 25%
Answer:
Less than 25%
Step-by-step explanation:
1. Find the difference of the two numbers: 1,207 - 957 = 250
decrease = original number - new number
2. Then, divide the decrease by the original number
250/1,207 = 0.207
3. Multiply the answer by 100 to get the percentage
0.207 x 100 = 20.7%
Therefore, the number of people fell by 20.7%
Hence, the answer is less than 25%

To determines the number of cups of flour that would be needed to make an entire batch of cookies.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
1 1/2 cups of flour => 1/4 batch of cookies
3/2 cups of flour => 1 / 4 batch of cookies
Multiply by both sides,
4 * 3 / 2 cups of flour => 4 * 1 / 4 batch of cookies
6 cups of flour => 1 batch of cookies
Thus, 6 cups of flour would be needed to make an entire batch of cookies.

A student says that the graph of the equation y = 3(x + 8) is the same as the graph of y = 3x, only translated upwards by 8 units. Do you agree? Why or why not?
A.S.A.P. I HAVE TO TURN THIS IN AT 10:30 HURRY PLEASE :)
Given:
A student says that the graph of the equation [tex]y = 3(x + 8)[/tex] is the same as the graph of [tex]y = 3x[/tex], only translated upwards by 8 units.
To find:
Whether the student is correct or not.
Solution:
Initial equation is
[tex]y=3x[/tex]
[tex]f(x)=3x[/tex]
Equation of after transformation is
[tex]y=3(x+8)[/tex]
[tex]g(x)=3(x+8)[/tex]
Now,
[tex]g(x)=f(x+8)[/tex] ...(i)
The translation is defined as
[tex]g(x)=f(x+a)+b[/tex] ...(ii)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
From (i) and (ii), we get
[tex]a=8\text{ and }b=0[/tex]
Therefore, the graph of [tex]y=3x[/tex] translated left by 8 units. Hence, the student is wrong.
