Answer:
(x-rooot1)(x-root2)
Step-by-step explanation:
a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis
(x-rooot1) (x-root2)=0
and you can find the roots by making each parenthesis equal to 0 because of the zero product rule
x-root1 = 0, x=root1
x-root2 =0, x=root2
-2/5x + 3= 2/3x + 1/3
Answer:
x=2.5
Step-by-step explanation:
In this case, simplification can isolate x, so x=2.5.
Shopping spree. Greg is shopping in a large urban depart-
ment store with many floors. He enters the store on the
middle floor from a skyway, and he goes directly to the
credit department. After making sure his credit is good, he
goes up three floors to the housewares department. Then
he goes down five floors to the sporting goods department.
Next, he goes up six floors to the media department. Finally,
he
goes
down ten floors to the main entrance to the store on
the first floor at ground level and leaves to go to another store.
How many floors does this department store have if it has no
basement?
Answer:
12 floors
Step-by-step explanation:
middle +3 floors= +3 .
+3 - 5 = -2.
-2 + 6= +4.
+4 - 10 = 6 x 2 = answer 12
to clarify the plus or minus mean how many floors he is above or below the middle floor
You newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton Descartes have 5040 volunteer min altogether how many min do you volunteer
Complete question is;
You, newton, and Descartes volunteer this summer. You have 2 times as many volunteer min as newton and Descartes. You all have 5040 volunteer min altogether. how many min do you volunteer?
Answer:
2520 volunteer minutes
Step-by-step explanation:
You have 2 times as many volunteer minutes as Newton and Descartes.
Now, if Newton and Descartes each have x volunteer minutes, it means you have 2x volunteer minutes.
Since the total volunteer minutes of the 3 of you is 5040,then we have;
2x + x + x = 5040
4x = 5040
x = 5040/4
x = 1260
Since you have 2x volunteer minutes, then you have: 2 × 1260 = 2520 volunteer minutes

x = 1 while(x < 26) print(x) x = x + 1 There is an error in the while loop. What should be fixed? Add a colon to the end of the statement Begin the statement with the keyword count Change the parentheses around the test condition to quotation marks Use quotation marks around the relational operator
Answer:
Add a colon to the end of the statement
Step-by-step explanation:
Given
x = 1
while(x < 26)
print(x)
x = x + 1
Required
Spot and fix the error
Every lines of the given code segment is correct except the second line.
The syntax of a while loop is:
while(condition):
Comparing while(condition): to while(x < 26),
we'll see that while(x < 26) has a missing colon.
So, the error in the program is a missing colon and the solution is (option a) adding a colon to the end of the while statement
So, the correct code segment is:
x = 1
while(x < 26):
print(x)
x = x + 1
Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher.
How old is Ishaan?
Answer:
Ishaan is 21. Christopher is 7.
Answer: Ishann is 21 years old.
Step-by-step explanation:
In this situation, we will represent Ishaan age by the variable y and we will represent Christopher's age by x.
Ishaan is 3 times as old as Christopher and that can be represented by the equation, y = 3x
He is also 14 years older, and it can also be represented by the equation,
y = x + 14.
y= 3x
y = x + 14
Using both equations, substitute the value of y in one of the equations into the other.
x + 14 = 3x Solve for x .
-x -x
14 = 2x
x = 7
This means that Christopher is 7 years old.
To solve for Ishaan's age , input the value of x into one of the equations.
y = 3(7)
y = 21.

Answer:
[tex]\frac{5}{8}[/tex]
Step-by-step explanation:
[tex]\frac{5}{1}[/tex] × [tex]\frac{1}{8} = \frac{5}{8}[/tex]I hope this helps!
Answer:
5/8 or 0.625
Step-by-step explanation:
multiply the numerator so that equals 5
multiply the denominator so that equals 8
the fraction answer is 5/8
the decimal answer is 0.625; this is because when you divide 5 and 8, you get 0.625
if you need more explanation, 5/1 times 1/8

Answer:
As a fraction: 81/100 (cannot be simplified) Decimal: 0.81 and a percent 81%
Step-by-step explanation:
Count the blocks and convert (you can also use an array.) Hope this helps you!
Answer:
Fraction: 81/100
Decimal: 0.81
Percent: 81%
Step-by-step explanation:
The box is a 10x10 so it has 100 squares inside.
There are 81 squares shaded so the fraction would be 81/100
To get the decimal just divide 81 by one hundred so the decimal is .81
As a percent is would be 81%

Twice as many students go to the park than to the theater. Five more students go to the theater than to the museum. If 16 students go to the park, how many students go to the museum?
Answer:
3 students
Step-by-step explanation:
Twice as many students go to the park than to the theater :
Let number who go the theater = t
Number who goes to park = 2t
5 more students go to the theater than to the museum
Number who goes to museum = t - 5
If number of students who goes to park = 16
How many students goes to the museum :
2t = 16
t = 16/2
t = 8
Number who goes to museum = t - 5
t - 5 = 8 - 5 = 3
Hence, number of students who goes to the museum = 3
2x to the power of negative 1, multiplied by 4x squared equals
Answer:
=-8x^3
Step-by-step explanation:
=2x^-1×4x^2
=-2x×4x^2
=-8x^3
(2x)⁻¹ × (4x)² = 8x
2x to the power of negative 1 is represented as follows
(2x)⁻¹The value((2x)⁻¹) multiplied by 4x squared is represented as follows
(2x)⁻¹ × (4x)²Therefore,
(2x)⁻¹ × (4x)² = (2x)⁻¹ × 16x²
(2x)⁻¹ × 16x² = [tex]\frac{1}{2x}[/tex] × 16x²
[tex]\frac{1}{2x}[/tex] × 16x² = 8x

Answer and Step-by-step explanation:
We are asked to find the percentage of each asset or liability in total assets and liabilities. To find percentage of each asset or liability in the balance sheet, we divide the asset or liability's value(from each year in the balance sheet) by total assets and liabilities for that year and multiply by 100:

Given the following system, the x-value of the solution is -1. Solve for y.
Answer:
1. y=3
2. y=3
Step-by-step explanation:
Let's start with the first one, 2x-2y=-8...
Substitute x with -1 -----> 2(-1)-2y=-82 times -1 makes -2 so new equation is ---> -2-2y=-8Now add 2 on each side to get rid of 2 and get this ----> -2y=-6Now divide -6 by -2 to get this ----> y=3Let's start with the second one, 2x+2y=4
Substitute x with -1 -----> 2(-1)+2y=42 times -1 makes -2 so new equation is ---> -2+2y=4Now add 2 on each side to get rid of 2 and get this ----> 2y=6Now divide 6 by 2 to get this ----> y=3I hope my explanation and answer helps:)
