−5(w−5)=−5
Solving Multi-Step Equations Using the Distributive Property
Answer:
w=6
Step-by-step explanation:
−5(w−5)=−5
= divide both sides by -5
=w-5=1
add 5 to both sides
= w=6
Answer:
w=6
Step-by-step explanation:
5(w−5)=−5
(−5)(w)+(−5)(−5)=−5(Distribute)
−5w+25=−5
Step 2: Subtract 25 from both sides.
−5w+25−25=−5−25
−5w=−30
Step 3: Divide both sides by -5.
−5w−5=−30−5
w=6

Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.
Write the following equation in standard form: x^5+2x^3+6x+1/5
Answer: B
Step-by-step explanation:
It already is in standard form.
The equation in standard form is: 5x^5 + 10x^3 + 30x + 1.
How to determine the standard form: x^5+2x^3+6x+1/5To write the equation in standard form, we need to arrange the terms in descending order of exponents and remove any fractions.
The given equation is:
x^5 + 2x^3 + 6x + 1/5
To eliminate the fraction, we can multiply the entire equation by 5:
5(x^5 + 2x^3 + 6x + 1/5)
This simplifies to:
5x^5 + 10x^3 + 30x + 1
So the equation in standard form is:
5x^5 + 10x^3 + 30x + 1.

Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan
Answer:
449.10
Step-by-step explanation:
Her monthly payment, if she is considering a three-year loan is $373.47
Given the cost of the motorcycle to be $14000
If the tax rate is 6.75%, the total cost plus tax is expressed as:
Final cost = 14000+(0.0675 * 14000)
Cost of motorcycle = 14000 + 945
Cost of motorcycle = $14945
If she plans to make a down payment of $1,500 before the sales tax is applied, then;
Balance = 14945 - 1500
Balance = $13,445
If she considers a three-year loan, her monthly payment will be ;
Monthly payment = 13,445/36
Monthly payment = $373.47
Hence her monthly payment if she is considering a three-year loan is $373.47

The probability that the selected student is a sophomore given that he is a boy will be 5/12.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
we need to select the probability that the selected student is a sophomore given that he is a boy;
In this case;
P(B) = P(boy)
P(A) = P(sophomore)
The total number of students which is 12 + 18 = 30
From the table;
P(B) = 12/30
P(A n B) = 5/30
So;
P(A|B) = 5/30 / 12/30
= 5/30 x 30/12 = 5/12
Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.

Use the quadratic formula to find the solutions to the equation.
3x2 - 10x + 5 = 0
Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
