Daniel's total time is 4.04 second greater than Ryan's total time.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
Ryan runs 100 m two times. His times were 14.19 s and 13.78 s.
Daniel runs 100 m two times. His times were 15.77 s and 16.24 s.
The total time taken by Ryan will be
⇒ 14.19 + 13.78
⇒ 27.97 seconds
The total time taken by Daniel will be
⇒ 15.77 + 16.24
⇒ 32.01 seconds
The difference of the Daniel time to Ryan time will be
⇒ 32.01 – 27.97
⇒ 4.04 seconds
Daniel's total time is 4.04 second greater than Ryan's total time.

What is the value of n in the equation (n – 4) – 3 = 3 – (2n + 3)?
Answers
n - 4 = 3 - 2n
n = 3 - 2n + 4
n = -2n + 7
n + 2n = 7
3n = 7
n = 7/3
The answer is in bold
Let's first start by removing the parenthesis.
(n-4) = +(n-4) so we just remove the parenthesis without changing the signs. So the first part of the equation will be n - 4 - 3.
Before (2n+3), we can notice a minus sign (-) which means that to remove the parenthesis, we need to change the signs of the numbers and variables inside.
-(2n+3) = -2n-3
So the second part of the equation becomes 3 -2n - 3
(n-4) - 3 = 3 - (2n+3)
n - 4 - 3 = 3 - 2n - 3
n - 7 = -2n
Now we need to put the variables apart and the constants apart. So we subtract n from each side:
n - n - 7 = -2n - n
-7 = -3n
Divide both sides by -3
(-7)/(-3) = (-3n)/-3
7/3 = n
In the equation (n-4) - 3 = 3-(2n+3), the value of n is n=7/3

Laura decides to walk to her job. She walks 1 1/2 miles in 3/5 hour. What is Laura’s walking rate?
Answers
Final answer:
Laura's walking rate is calculated by dividing the distance she walked, 1.5 miles, by the time it took, 0.6 hour. Her walking rate is 2.5 miles per hour.
Explanation:
Laura's walking rate can be calculated by dividing the distance she walked by the time it took. Laura walked 1 1/2 miles in 3/5 hour. To find her rate, we will convert 1 1/2 miles to a decimal, which is 1.5 miles, and we convert 3/5 of an hour to minutes or hours in decimal form. Since 3/5 of an hour is the same as 36 minutes (because 60 minutes * 3/5 = 36), we can calculate Laura's walking rate.
To find the rate, we use the formula:
Rate = Distance ÷ Time
So Laura's walking rate is:
Rate = 1.5 miles ÷ 0.6 hour
Rate = 2.5 miles per hour (since 1.5 ÷ 0.6 = 2.5)
Therefore, Laura walks at a rate of 2.5 miles per hour.

Step-by-step explanation:
Solve M=h-w/8 for the variable H
Solve the above equation for W
Solve w=x+y/z for y
Solve the equation above for z
The formula for area of a triangle is A=1/2b solve this equation for B
Solve the equation P=kt/v for the letter K
Answers
Subtract h from both sides.
m - h = -w/8
Subtract m from both sides.
-h = -m - w/8
Divide all terms by -1.
h = m + w/8.
2) m = h - w/8
Get rid of the denominator 8 by multiplying 8/1 to all terms.
8m = 8h - w
Add w on both sides and subtract 8m from both sides.
w = 8h - 8m
3) w = x + y/z
Get rid of the denominator z by multiplying it to all terms.
wz = xz + y
Subtract xz from both sides of the equation.
wz - xz = y OR y = wz - xz
4) w = x + y/z
Subtract x from both sides.
w - x = y/z
Get rid of the denominator by multiplying it to all terms.
wz - xz = y
Now factor the expression wz - xz.
z(w - x) = y
Divide both sides by w - x.
z = y / w - x
This is read as z equals to y divided by w minus x.
5) The area of a triangle is A = 1/2bh
First, get rid of the denominator by multiplying both sides by 2.
2A = bh
To find b, divide both sides by h.
2A/h = b
6) P = kt/v
Multiply both sides by v.
Pv = kt
Divide both sides by t.
Pv/t = k OR k = Pv/t.
Answer:
Step-by-step explanation:
(1) M = h - [tex]\frac{w}{8}[/tex]
h = M + [tex]\frac{w}{8}[/tex]
(2) M = h - [tex]\frac{w}{8}[/tex]
M - h = -[tex]\frac{w}{8}[/tex]
[tex]\frac{w}{8}[/tex] = h - M
w = 8(h - M)
(3) w = x + [tex]\frac{y}{z}[/tex]
(w-x) = [tex]\frac{y}{z}[/tex]
[tex]\frac{z}{y}[/tex] = [tex]\frac{1}{(w-x)}[/tex]
z = [tex]\frac{y}{w-x}[/tex]
(5) Area of triangle A = [tex]\frac{1}{2}b[/tex]
b = 2A
(6) [tex]P=\frac{kt}{v}[/tex]
⇒ PV = kt
⇒ k = [tex]\frac{PV}{t}[/tex]

How to turn 17/20 into percent
Answers
multiply top and bottom by 5 ( need to be over 100)
17 x 5 = 85
20 x 5 = 100
85/100 = 0.85
0.85 = 85%
85% is your answer
hope this helps
20*5=100
17*5=85
then, put the product of the numerator and 5 over the product of the product of the denominator and 5.
85/100.
So, 17/20 as a percent is 85%

nadia was offered a job for selling ads cor a magazine. She must agree to one of the following paymen options. CHOICE A:$110 for each ad she sells. CHOICE B:a weekly salary of $150,plis $85 for each ad she sells .Wriye and solve an inequality to determine the number of adds nadia would need to sell per week in order for Choice A to be a better choice
Answers
Let us say that:
x = is the number of ads that Nadia sold every week
P = payment or amount that she receives every week
So the equations we can formulate for choice A and B are:
choice A: P = 110 x
choice B: P = 150 + 85 x
The amount that she receives for A must be greater than she receives for choice B, so:
110 x > 150 + 85 x (inequality equation)
Calculate for x:
110 x – 85 x > 150
25 x > 150
x > 6
Therefore Nadia must sell more than 6 ads every week so that Choice A would be the better choice.
Final answer:
Nadia would need to sell more than 6 ads per week for Choice A to be a better choice than Choice B. We find this by setting up an inequality of 110x > 150 + 85x (where x represents the number of ads sold), then solving for x.
Explanation:
To determine the number of ads Nadia would need to sell per week for Choice A to be a better choice, we can set up the following income inequalities based on her two payment options:
Choice A: $110 per ad sold.
Choice B: $150 weekly salary + $85 per ad sold.
We want to find when Choice A's income exceeds Choice B's income:
Let x be the number of ads sold. Then, the inequality is:
110x > 150 + 85x
To solve for x:
Subtract 85x from both sides: 110x - 85x > 150
This simplifies to: 25x > 150
Divide both sides by 25: x > 6
Therefore, Nadia would need to sell more than 6 ads per week for Choice A to be the better choice.
