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
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.

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]

solve 2x+y=3.5,-x+2y=2.5
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

2x - 3 = 5(x + 4) + 1 solve for x and show work
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
is x=25?
