In a week Mike ran 8 km farther than Bill, while Pete ran
1 km less than 3 times as far as Bill. If Pete ran 15 km
farther than Mike, how many kilometers did Bill run?
Answer:
12 km
Step-by-step explanation:
m = b + 8
p = 3b - 1
p = m + 15
p = m + 15....and m = b + 8....so we are gonna sub
p = b + 8 + 15
p = b + 23
b + 23 = 3b - 1
23 + 1 = 3b - b
24 = 2b
24/2 = b
b = 12 <==== Bill ran 12 km
m = b + 8
m = 12 + 8
m = 20 km....this is what mike ran
p = m + 15
p = 20 + 15
p = 35 km....this is what pete ran
Bill ran a distance of 12 kilometers. This was determined through algebraic calculations, taking into account the given information about the distances run by Mike, Pete, and the relationships between their distances.
Let's use algebra to solve this problem. We'll denote the distances run by each person:Bill's distance: B kmMike's distance: B + 8 km (Mike ran 8 km farther than Bill)Pete's distance: 3B - 1 km (Pete ran 1 km less than 3 times as far as Bill)Now, we're given that Pete ran 15 km farther than Mike:Pete's distance (3B - 1) = Mike's distance (B + 8) + 15Now, let's set up this equation:3B - 1 = B + 8 + 15Now, solve for B:3B - 1 = B + 23Subtract B from both sides:2B - 1 = 23Add 1 to both sides:2B = 24Now, divide by 2:B = 24 / 2B = 12So, Bill ran 12 km.For more questions on algebraic calculations -

A bank offers 2.12 interest compounded annually for investing money in a savings account, you open an account with $300. How much money in interest big you leave it for 10 years
Answer:
[tex]\large \boxed{\$70.02}[/tex]
Step-by-step explanation:
The compound interest formula is
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]
Data:
P = 300
r = 2.12 % = 0.0212
t = 10 yr
n = 1 calculation per year
1. Accrued amount:
A = 300(1+ 0.0212)¹⁰
= 300 × 1.0212¹⁰
= 300 × 1.233 41
= 370.02
2. Interest
I = A - P = 370.02 - 300.00 = 70.02
[tex]\text{The interest is $\large \boxed{\mathbf{\$70.02}}$}[/tex]
Final answer:
Using the compound interest formula, investing $300 at an annual interest rate of 2.12% compounded annually for 10 years will result in approximately $70.37 in interest, totaling $370.37.
Explanation:
A bank offers 2.12% interest compounded annually for investing money in a savings account, and you open an account with $300. How much money in interest will you earn if you leave it for 10 years?
To calculate the amount of money you will have after 10 years, including interest, you can use the formula for compound interest: [tex]A = P(1 + r/n)^{(nt)[/tex], where:
P = principal amount (initial investment) is $300,r = annual interest rate in decimal form, which is 0.0212 for 2.12%,n = number of times the interest is compounded per year, which is 1 since it's compounded annually,t = time the money is invested for in years, which is 10 years.Plugging these values into the formula gives us: [tex]A = $300(1 + 0.0212/1)^{(1*10)[/tex] = [tex]$300(1 + 0.0212)^{10[/tex] = [tex]$300(1.0212)^{10.[/tex]
Calculating this, we get A = $300(1.234567), which equals approximately $370.37. Therefore, the total interest earned over 10 years is approximately $70.37.

Complete the equation of the line through
(-6, -5) and (-4,-4).
Use exact numbers.
Answer:
y = [tex]\frac{1}{2}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)
m = [tex]\frac{-4+5}{-4+6}[/tex] = [tex]\frac{1}{2}[/tex], thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 6, - 5), then
- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2
y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line
To find the equation of the line through (-6, -5) and (-4, -4), calculate the slope and then apply the point-slope form to yield the line equation y = 1/2x - 2.
Explanation:The question is about finding the equation of the line that passes through two given points, (-6, -5) and (-4, -4). To do this, we first need to find the slope of the line (m) using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the points, we get m = (-4 + 5) / (-4 + 6) = 1 / 2. Next, we use the point-slope form of a linear equation, y - y1 = m(x - x1), to find the equation. Using point (-6, -5) and the slope 1/2, the equation becomes y + 5 = 1/2(x + 6). Finally, simplifying, we get y = 1/2x - 2 as the completed equation of the line.
Harold had a summer lemonade stand where he sold small cups of lemonade for $1.25 and large cups for $2.50. Harold sold a total of 155 cups of lemonade and collected a total of $265, how many cups of each type did he sell.
98 small cups of lemonade and 57 large cups of lemonade were sold by Harold.
Step-by-step explanation:
Given,
Cost of small cup of lemonade = $1.25
Cost of large cup of lemonade = $2.50
Total cups sold = 155
Total worth of cups = $265
Let,
x be the number of small cups sold
y be the number of large cups sold
According to given statement;
x+y=155 Eqn 1
1.25x+2.50y=265 Eqn 2
Multiplying Eqn 1 by 1.25
[tex]1.25(x+y=155)\\1.25x+1.25y=193.75\ \ \ Eqn\ 3[/tex]
Subtracting Eqn 3 from Eqn 2
[tex](1.25x+2.50y)-(1.25x+1.25y)=265-193.75\\1.25x+2.50y-1.25x-1.25y=71.25\\1.25y=71.25[/tex]
Dividing both sides by 1.25
[tex]\frac{1.25y}{1.25}=\frac{71.25}{1.25}\\y=57[/tex]
Putting y=57 in Eqn 1
[tex]x+57=155\\x=155-57\\x=98[/tex]
98 small cups of lemonade and 57 large cups of lemonade were sold by Harold.

Hope this helps! Please correct me if I'm wrong! :D
4r + 5 = 3 is not an algebraic expression because it contains an equals sign making it an equation rather than an algebraic expression. Algebraic expressions are mathematical phrases lacking an equals sign.
Explanation:The equation 4r + 5 = 3 is not an algebraic expression because it is, in fact, an equation. The distinction between these two lies in the presence of the equals sign (=).
An algebraic expression is a mathematical phrase that can contain numbers, variables, and operators (like +, -, ×, ÷), but it does not have an equals sign. For example, 4r + 5 is an algebraic expression. However, when there is an equals sign present, as is the case in 4r + 5 = 3, the resulting mathematical phrase is an equation, which is a statement that two algebraic expressions are equal.
