Answer:
x = (-3±√69)/10
Step-by-step explanation:
Perhaps you want to find the solutions using the quadratic formula.
For the equation ...
ax² +bx +c = 0
The solution is given by the formula ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Here, we have a=5, b=3, c=-3, so the values of x are ...
[tex]x=\dfrac{-3\pm\sqrt{3^3-4(5)(-3)}}{2(5)}\\\\\boxed{x=\dfrac{-3\pm\sqrt{69}}{10}}[/tex]

Add one-half to 9 times p
Answer:
1/2 + 9(p)
Step-by-step explanation:
Answer:
[tex]\frac{1}{2}[/tex] + 9p
Step-by-step explanation:
add one-half can translate to +[tex]\frac{1}{2}[/tex], so we know that this needs to be in the expression somewhere
the "to" means that the sentences is going to state the next term in the expression
9 times p means 9 multiplied by p, and this can be written as 9p
so put our terms together to get [tex]\frac{1}{2}[/tex] + 9p

Daniel works no more than 16 hours a week while attending college. He wants to spend at least 2 hours but no more than 10 hours a week parking cars. He is paid $8 (x) and $7 per hour working at the Haul-mart store (y). What are Daniels maximum earnings?
Answer:
The maximum earning is $122
Step-by-step explanation:
The computation of the Daniel maximum earnings is as follows;
Since there is total of 16 hours
so 10 hours would be for parking cars and the remainig hours i.e.
= 16 hours - 10 hours
= 6 hours
This above hours for working at store
So,
= 10 hours × $8 + 6 hours × $7
= $80 + $42
= $122
Hence, the maximum earning is $122

At the Beginning of the month Kiran had $24 in his school cafeteria account.
In the first week he spent $16.00 on lunches. How much was in his account then?
Then he deposited some more money and his account balance was $28. How much did he deposit?
Then he spent $34 on lunches in the next week. How much was in his account then?
Then he deposited enough money to pay off his debt to the cafeteria. How much did he deposit?
(a) Kiran has $8 in account after spending $16 on lunch.
(b) Kiran deposit $8 in account.
(c) After spending $34 on lunches, Kiran has -$14 in account .
(d) $14 Kiran have to deposit to pay debt.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
At the beginning, the money in Kiran's account = $24
(a)
Since, in the first week amount spend by Kiran on lunches = $16
Remaining amount = 24 - 16 = 8
(b)
Then Kiran deposits some money, then total amount in account becomes $28
Let Kiran deposits x amount
8 + x = 28
x = 20
(c)
Then Kiran spent $34 on lunches,
Remaining amount in Kiran's account = 20 - 34 = -14
(d)
Kiran has $14 debt,
To pay debt, Kiran needs to deposit $14.

what number when added to 1 1/3 gives 2?
Answer:
2/3
Step-by-step explanation:
The answer is 2/3 because 1/3 + 2/3 = 1. So when you take the 1 you already had and add the new 1 you get 2.
The number that can be added to 1 1/3 gives 2 is 2/3
Solution:
Subtract 1 1/3 from 2 to get the number
2 - 1 1/3
= 2 - 4/3
= (6-4) / 3
= 2/3
check:
1 1/3 + 2/3
= 4/3 + 2/3
= (4 + 2) / 3
= 6/3
= 2
Therefore, the number that can be added to 1 1/3 gives 2 is 2/3

PLEASE HELP ME! & FIND Y
Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine Rule in Δ XYZ
cosY = [tex]\frac{x^2+z^2-y^2}{2xz}[/tex]
Here x = 22, y = 20, z = 22, then
cosY = [tex]\frac{22^2+18^2-20^2}{2(22)(18)}[/tex]
= [tex]\frac{484+324-400}{792}[/tex]
= [tex]\frac{408}{792}[/tex] , thus
Y = [tex]cos^{-1}[/tex] ( [tex]\frac{408}{792}[/tex] ) ≈ 59.0° ( to the nearest tenth )
