What are the solutions to the equation (10−x)(3x−9)=0?
Answer:
10−x)(3x−9)=0
−3x2+39x−90=0
−3(x−3)(x−10)=0
x=3 or x=10
The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.
Given that the equation (10 - x)(3x - 9) = 0
The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.
To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to 0
To determine the solutions of (ax + b)(cx + d), equate each term to zero and solve for x which gives the solutions.
The two solutions of (ax + b)(cx + d) are -b/a and -c/d.
To find the solutions to the equation (10 - x)(3x - 9) = 0, set each factor equal to zero and solve for x.
Setting (10 - x) = 0 gives:
10 - x = 0
To isolate x, subtract 10 from both sides of the equation:
10 - x - 10 = 0 - 10
Simplifying gives:
-x = -10
Multiplying both sides by -1 to solve for x:
(-1)(-x) = (-1)(-10)
x = 10
So, one solution is x = 10.
Now, setting (3x - 9) = 0, gives:
3x - 9 = 0
To isolate x, we add 9 to both sides of the equation:
3x - 9 + 9 = 0 + 9
Simplifying gives:
3x = 9
Dividing both sides by 3 to solve for x:
(1/3)(3x) = (1/3)(9)
x = 3
Therefore, the second solution is x = 3.
The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

one summer, the average price of a gallon of gas in Cleveland was $1.094 while the average price of gas in New York was 1.332. to the nearest penny (round to the nearest penny or hundredths) how much more did a gallon of gas cost in New York than in Cleveland?
Answer:
$0.24
Step-by-step explanation:
1.332 - 1.094 = 0.238
Answer: 0.24
It cost $0.24 more in New York, than in Cleveland
You can find the answer by subtracting the larger price from the smaller price like so
[tex]1.332 - 1.094= 0.238[/tex]
Since it says to round to the nearest hundredths
[tex]0.238[/tex] becomes [tex]0.24[/tex]

A house has increased in value by 35% since it was purchased. If the current value is 648,000, what was the value when it was purchased?
Answer:
Purchase rate of the house is $480000.
Step-by-step explanation:
Let the purchase rate of the house = $p
Current value of the house = $648000
If the current rate of the house has increased by 35% of the purchase rate,
Current rate = Purchase rate + 35% of the purchase rate
648000 = p + (35% of p)
648000 = p + [tex]p\times \frac{35}{100}[/tex]
648000 = p + 0.35p
648000 = (1.35)p
p = [tex]\frac{648000}{1.35}[/tex]
p = $480000
Therefore, purchase rate of the house is $480000.

Answer:
8in
Step-by-step explanation:
I hope this helps. have a great dsy
Answer:
perimeter of a rectangle = 2( l+b )
perimeter = 60 inches
length = 22 inches
∴ width =
2 ( 22 + b ) = 60
22 + b = 60/2 = 30
22 + b = 30
b = 30 - 22 = 8 inches
∴ width = 8 inches

Mofor and Shanice are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Mofor sold 12 small boxes of oranges and 3 large boxes of oranges for a total of $96. Shanice sold 6 small boxes of oranges and 6 large boxes of oranges for a total of $84. Find the cost each of one small box of oranges and one large box of oranges.
Answer:
$6 = cost of small box
$8 = cost of large box
Step-by-step explanation:
Let s = cost of small box
l = cost of large box
(1) 12s + 3l = 96 (2) 6s + 6l = 84
Multiply by -2 -24s - 6l = -192
-18s = - 108
s = $6 = cost of small box
12(6) + 3l = 96
72 + 3l = 96
3l = 24
l = $8 = cost of large box

The diameter of a circle is 6 feet find its area to the nearest 10th
Answer:
The area of the circle is 113.0 ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6ft
π = 3.14
a = π * r²
we replace with the known values
a = π * (6ft)²
a = π * 36ft²
a = 113.04ft²
The area of the circle is 113.04ft²
round to the nearest tenth
a = 113.04ft² = 113.0 ft²
