20= m÷-5
Answer:
The solution to the equation 20 = m ÷ -5 is m = -100
To see this, we can multiply both sides of the equation by -5 to isolate the variable m:
20 × -5 = m ÷ -5 × -5
Expanding the right side of the equation:
20 × -5 = m × 1
Combining like terms:
-100 = m
And the solution is:
m = -100
Verification:
To verify the solution, we can plug in the value of m back into the original equation and see if it is true:
20 = -100 ÷ -5
Expanding -100 ÷ -5:
20 = 20
Since 20 = 20 is a true statement, we have verified that the solution m = -100 is correct.

The equation of the line is (y - 1/12) = -4/3(x - 7/5).
What is the slope of a line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are represented by y and x, respectively.
Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is
m = y/x = y/x = change in y/change in x
where "m" represents a line's slope.
Additionally, the slope of the line can be depicted by
tan θ = Δy/Δx
So, the slope of a line is tan.
The given equation of a line is:
3x-4y=7

The 5th , 6th and 7th term of the arithmetic sequence is 1 , 13/16 and 10/16 respectively
What is Arithmetic Progression?An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the first term of the AP be a₁ = 1 3/4
Let the second term of the AP be a₂ = 1 9/16
So , the common difference of AP d = a₂ - a₁
On simplifying the equation , we get
The common difference d = 1 9/16 - 1 3/4 = ( 25/16 - 7/4 )
The common difference d = - ( 3/16 )
And , the nth term of the AP is a + (n - 1) d
So , the 5th term of the AP = ( 1 3/4 ) + ( 4 ) ( -3/16 )
On simplifying the equation , we get
The 5th term of the AP = ( 7/4 ) + ( -3/4 )
The 5th term of the AP = 4/4 = 1
Therefore , the value of A = 1
And , the 6th term of the AP = ( 1 3/4 ) + ( 5 ) ( -3/16 )
On simplifying the equation , we get
The 6th term of the AP = ( 7/4 ) + ( -15/16 )
The 6th term of the AP = 13/16
Therefore , the value of B = 13/16
And , the 7th term of the AP = ( 1 3/4 ) + ( 6 ) ( -3/16 )
On simplifying the equation , we get
The 7th term of the AP = ( 7/4 ) + ( -18/16 )
The 7th term of the AP = 10/16
Therefore , the value of C = 10/16

Carlos had $400. He decided to spent 40% of it on clothes, and 50% of the remaining money on video games. How much money did Carlos spend? How much does Carlos have left?
Answer:
Step-by-step explanation:
We can start by finding how much money Carlos spent on clothes. To do this, we simply multiply the original amount of $400 by 40%:
Clothes = $400 * 40% = $400 * 0.40 = $160
Next, we find how much money Carlos has left after spending on clothes. To do this, we subtract the amount spent on clothes from the original amount:
Remaining Money = $400 - $160 = $240
Finally, we find how much money Carlos spent on video games. To do this, we multiply the remaining money by 50%:
Video Games = $240 * 50% = $240 * 0.50 = $120
So, in total, Carlos spent $160 on clothes and $120 on video games, for a total of $160 + $120 = $280.
And Carlos has $400 - $280 = $120 left.
After spending 40% of the $400 on clothes, Carlos has $400 x (100 - 40) / 100 = $240 left.
Next, he spent 50% of the remaining $240 on video games, which is $240 x 50 / 100 = $120.
Therefore, Carlos spent a total of $400 - $240 = $160.
Finally, Carlos has $240 - $120 = $120 left.

four times the sum of the three consecutive even intergers is 240 more than six times the smallest integer.
Answer:
Step-by-step explanation:
Let's call the smallest of the three consecutive even integers "x". Since they are consecutive and even, we know that the next two integers must be "x + 2" and "x + 4".
Now we can set up the equation for the problem:
4 * (x + (x + 2) + (x + 4)) = 240 + 6x
Expanding the parentheses on the left side:
4 * (3x + 6) = 240 + 6x
Simplifying the left side:
12x + 24 = 240 + 6x
Subtracting 6x from both sides:
6x + 24 = 240
Subtracting 24 from both sides:
6x = 216
Dividing both sides by 6:
x = 36
So the smallest of the three consecutive even integers is 36, and the others are 38 and 40.

and growing at an annual rate of
2004.
an amal rate of 2,8%. Let (B) Express P as an exponential function using base e
Answer:
P = 72.5 * e^(0.025t)
Step-by-step explanation:
Here's a step by step solution with all the details and calculus involved.
(a) Express P as a function in the form P = Poat.
Since the population is growing continuously at a rate of 2.5% per year, we can use the formula for continuous growth:
P = Po * e^(rt)
where Po is the initial population (72.5 million), r is the continuous growth rate (0.025), and t is the time elapsed in years since 2004.
The continuous growth rate, r, is related to the annual growth rate, g, by:
r = g / 100
So, the continuous growth rate is 0.025.
Substituting the values into the formula for continuous growth, we get:
P = 72.5 * e^(0.025t)
This is the expression for the population as a function of time in the form P = Poat.
(b) Express P as an exponential function using base e.
The exponential function using base e is already in the desired form. So, we can simply write:
P = 72.5 * e^(0.025t)

25(y-64)=-10(x-10)
5(y-64)=-2(x-10)
5y-320=-2x+20
2x+5y=340
Therefore, the required equation of the line is 2x+5y=340.
To find the x-intercept, substitute y=0 into the equation of the line.
2x+5×0=340
2x=340
x=170
Therefore, the x-intercept point is (170,0).

Amelia wanted to redeem a voucher. She had only 3/5of the total number
of points needed. After she earned another 50 points, she still needed 3/10
of the total number of points. How many points were needed to
redeem the voucher?
Answer:
The number of points needed to redeem the voucher is 92.5
Step-by-step explanation:
Let x be the total number of points needed to redeem the voucher.
Amelia has [tex]\frac{3}{5}[/tex] × x points,before she earns the another 50 points,
After she earns another 50 points,
Now
she has [tex]\frac{3}{5}[/tex] × x + 50 points.
she still needs [tex]\frac{3}{10}[/tex] × x points to redeem the voucher.
Now
From above we get a equation,
[tex]\frac{3}{5}[/tex] × x + 50 = [tex]\frac{9}{10}[/tex] × x
Solving the equation we can get x,
[tex]\frac{3}{5}[/tex] × x = [tex]\frac{9}{10}[/tex] × x - 50
if we multiply both sides by 5/3, we get,
x = (9/10 × x - 50) × 5/3
After expanding the right side,
x = (9/10 × x - 50) × 5/3
x = (9x/10 - 250/3)
Now,
Subtracting 9x/10 from both sides,
0 = 250/3 - 9x/10
If we add 9x/10 to both sides,
9x/10 = 250/3
Again,
If we multiply both sides by 10/9,
x = 250/3× 10/9
x = 250 × 10 / (3 × 9)
x = 250 × 10 / 27
x = 250 × 10 / 27
x = 250 × 10 / 27
x = 250 × 10 / 27
= 250 × .37
x = 92.5
The number of points needed to redeem the voucher is 92.5
