Step-by-step explanation: 3root5x^2 + 25x - 10root5 = 0
3xroot5 + 25x - 10root5 = 0 [ root x^2 = x]
28x root5 = 10 root5 [ -10root5 turns to 10 root5 when transferred to RHS]
28x root 5/root5 =10
28x=10
x = 10/28
x = 0.35

3rd hour: 0.5 and 7
4th hour: 3 and 3
Answer:
after 52/3 hours
temparature will be at -151/3
Step-by-step explanation:
y = -2.5x - 7
y = -4x + 19
-2.5x - 7 = -4x + 19
4x - 2.5x = 19 + 7
1.5x = 26
1.5x = 26
3/2x = 26/1
2/3 x 3/2x = 26/1 x 2/3
x = 52/3
y = -4x + 19
y = -4(52/3) + 19
y = -208/3 + 19
y = -208/3 + 19/1
y = -208/3 + 57/3
y = -151/3

Edward Corsi, who later became United States Commissioner of Immigration, was a ten-year-old Italian immigrant when he sailed into New York harbor in 1907:
My first impressions of the New World will always remain etched in my memory, particularly that hazy October morning when I first saw Ellis Island. The steamer Florida, fourteen days out of Naples, filled to capacity with 1600 natives of Italy, had weathered one of the worst storms in our captain's memory; and glad we were, both children and grown-ups, to leave the open sea and come at last through the Narrows into the Bay.
My mother, my stepfather, my brother Giuseppe, and my two sisters, Liberta and Helvetia, all of us together, happy that we had come through the storm safely, clustered on the foredeck for fear of separation and looked with wonder on this miraculous land of our dreams.
The purpose of this excerpt is to help readers understand
A) the excitement and relief immigrants felt upon arriving in America.
B) that the Narrows into the Bay was a very dangerous passage.
C) that Italian children were very sad after leaving their home country.
D) the weather the immigrants experienced on that day in October 1907.

-7 - 12 = - 7х + 3(-4 - x)
Answers
Answer: x = -1.8
Step-by-step explanation:
-7 - 12 = -7x + 3 (-4 - x)
-7x + 3 (-4 - x) = -7 - 12
P.S I switched the order cuz I find it easier to solve this way.
-7x + 3 (-4 - x) = -7 - 12
Distribute
-7x - 12 - 3x = - 7 + 13
Add 12 to both sides
-7x - 3x = -7 + 13 + 12
Combine like terms
-10x = 18
Divide both sides by -10
x = -1.8
if f(x)=3x-2 find f-1 (13)
Answers
Answer:
Firstly
f(x)=3x-2=y then
Interchanging x and y we get
x=3y-2
x+2=3y
y=(x+2)/3
f-1(x)=(x+2)/3
f-1(13)=(13+2)/3
f-1(13)=5
A function is defined as a relation between a set of inputs having one output each.
The inverse of function f(x) = 3x - 2 is:
y = (x+2)/3
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain of the function.
The outputs are called the range of the function.
We have,
f(x) = 3x - 2
The inverse of f(x):
step 1:
Put f(x) = y
y = 3x - 2
step 2:
switch x and y
x = 3y - 2
step 3:
solve for y
x = 3y - 2
x + 2 = 3y
y = (x+2)/3
Thus,
The inverse of f(x) = 3x - 2 is y = (x+2)/3

о G Kelly opened a bank account that earns 1.2% simple interest each year. After 7 years, Kelly will earn $126 in interest. How much did Kelly deposit when she opened the account?
Answers
Answer:
$1,512
Step-by-step explanation:
1.2% of $126 = $1,512
I really dont l know if this is right but I think it is
Answer:
$15
Step-by-step explanation:
Interest=principle X interest rate X the time(In this case years)
So, $126= p X 1.2% X 7
We first multiply 1.2% by 7 and get .084, then we move the decimal to places to the right and get 8.4.After that we divide $126 by 8.4 and you should get 15.So thats how I got $15 but then again I may be wrong.Hope this works for you =)

A fruit company delivers its fruit in two types of boxes: large and small. Delivery of 4 large boxes and 8 small boxes has a total weight of 105 kilograms. Delivery of 2 large boxes and 3 small boxes has a total weight of 46 kilograms. How much does each type of box weigh?
Answers
Answer:
x = 13.25 kg
y = 6.5 kg
Step-by-step explanation:
Let
Large box = x
Small box = y
4x + 8y = 105 (1)
2x + 3y = 46 (2)
(Multiply (2) by 2 to eliminate x
2x + 3y = 46 (2) ×2
4x + 6y = 92 (3)
4x + 8y = 105 (1)
Subtract (3) from (1)
8y - 6y = 105 - 92
2y = 13
y = 13/2
y = 6.5kg
Substitute y = 6.5 into (2)
2x + 3y = 46 (2)
2x + 3(6.5) = 46
2x + 19.5 = 46
2x = 46 - 19.5
2x = 26.5
x = 26.5/2
x = 13.25 kg

Write2.1 as a mixed number and as an improper fraction.
Do not try to simplify your answers.
Answers
Answer:
2 1/10 and 21/10
Step-by-step explanation:
2.1 is 2 + 0.1 when expanded.
2 is just 2 and then 0.1 as a fraction is 1/10. The mixed number would be 2 1/10.
The improper fraction is just 21/10 (convert the mixed number into improper form).
Converting from mixed number to improper: Multiply the number in the front (in this case 2) by the denominator.
That is 2 x 10 which is 20. Then add that number (20) to the numerator. 20 + 1 is equal to 21.
21 would be our numerator and the denominator would stay the same (10).
21/10 is the improper form.

Mary is 50 years old.
She is 2 years older than Eric.
How old is Jack?
(2 marks)
Answers
Answer:
Jack is 16
48 divided by 3= 16
Eric is 48
50-2=48
The first step is to find the age of Eric, who is 2 years younger than Mary. Mary is 50 years old, so 50-2=48. Since Eric is three times Jacks age, we have to divide 48 by 3 to find his age. This comes to 16.
