Downers grove has gotten 5 inches of snow and the snow depth is increasing by 6 inches every hour. Woodridge has gotten 13 inches of snow and is increasing 2 inches every hour. In how many hours will the snowfall of the towns be equal.
Answer:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours

What is the slope of a line that passes through points (1,5) and (3,1)?
Answer:
Slope = -2
Step-by-step explanation:
(x₁, y₁) = (1 , 5) and (x₂ , y₂) = (3 , 1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{1- 5}{3 - 1}\\\\=\frac{-4}{2}\\\\= - 2[/tex]

The expression x^3 + ax^2 - 15x + b has a factor of x – 2 and leaves a remainder 75 when divided
by x + 3. Find the value of a and of b.
Answer:
The expression x^3 + ax^2 - 15x + b has a factor of x – 2 and leaves a remainder 75 when divided
by x + 3. Find the value of a and of b.
Let p(x) = x3 + ax2 + bx +6
(x-2) is a factor of the polynomial x3 + ax2 + b x +6
p(2) = 0
p(2) = 23 + a.22 + b.2 +6 =8+4a+2b+6 =14+ 4a+ 2b = 0
7 +2 a +b = 0
b = - 7 -2a -(i)
x3 + ax2 + bx +6 when divided by (x-3) leaves remainder 3.
p(3) = 3
p(3) = 33 + a.32 + b.3 +6= 27+9a +3b +6 =33+9a+3b = 3
11+3a +b =1 => 3a+b =-10 => b= -10-3a -(ii)
Equating the value of b from (ii) and (i) , we have
(- 7 -2a) = (-10 - 3a)
a = -3
Substituting a = -3 in (i), we get
b = - 7 -2(-3) = -7 + 6 = -1
Thus the values of a and b are -3 and -1 respectively.

Answer:
x=-8
Step-by-step explanation:
2x−3=5x+20+1
2x−3=5x+21
2x−3+3=5x+21+3
Then simplify those numbers
2x=5x+24
Then subtract 5x from both sides
Answer:
x=-8
Step-by-step explanation:
open brackets first
2x - 3 = 5x + 20 + 1
2x - 3 = 5x + 21
transpose
2x - 5x = 21+ 3
calculate
-3x = 24
x= -3/24
x= -8

Answer:
y=1.7
x=.9
Step-by-step explanation:
Answer:
x = 1.75 -y, y = 1.25 + x
Step-by-step explanation:
Part One
2x + y = 3.5
Divide
x + y = 1.75
Move the variable and change its sign
x = 1.75 -y
Part Two
-x + 2y = 2.5
Divide
-x + y = 1.25
Add
y = 1.25 + x

The distance cover by Noah in 1 hour to cover distance is 6.5 miles
Step-by-step explanation:
Given as :
The distance cover by Lin = 2 miles = miles
The time taken to cover distance by Lin = hours
Again
The distance cover by Noah = 8 miles = miles
The time taken to cover distance by Noah = hours
Let the distance cover by Noah in 1 hour = d miles
∵ The distance cover by Noah in hours = miles
∴ The distance cover by Noah in 1 hour =
I.e d = miles
or, d = = 6.5 miles
So, The distance cover by Noah in 1 hour = d = 6.5 miles
Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer
Mr. Smith had 3/4 of a peach pie left over. He spilt the leftover pie among his 3 co-workers. What fraction of the pie did each co-worker receive
Answer:
[tex]Fraction = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Pie = \frac{3}{4}[/tex]
[tex]Workers = 3[/tex]
Required
Determine the fraction received by each worker
To do this, we simply divide the fraction of the pie by the number of workers.
[tex]Fraction = \frac{Pie}{Workers}[/tex]
[tex]Fraction = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Fraction = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Fraction = \frac{3}{12}[/tex]
Divide numerator and denominator by 3
[tex]Fraction = \frac{3/3}{12/3}[/tex]
[tex]Fraction = \frac{1}{4}[/tex]

Answer:
The answer is 1,328
Step-by-step explanation:
The number of ounces that she weighs will be 1328 ounces. Then the correct option is D.
What is conversion?Conversion means converting the same thing into different units.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
If a child weighs 83 pounds. We know that in one pound, there are 16 ounces.
Then the number of ounces that she weighs will be
⇒ 83 x 16
⇒ 1328 ounces
Then the number of ounces that she weighs will be 1328 ounces. Then the correct option is D.
