Sonya buys four pairs of shoes on sale for buy one, get one 50% off. The sales tax is 6.5%. If the original price for each pair of shoes was $35, how much does Sonya pay for the four pairs altogether?
Answer:
$111.83
Step-by-step explanation:
2 pairs would be original price (35) and 2 would be half off (17.5)
35 + 35 + 17.5 + 17.5= $105
sales tax = 6.5 %
$105 * 6.5 % = 6. 825
$105 + 6.825= 111.825
round up since you cant have 825 cents

What’s the answer 40=16-8r ?
Answer:
-3
Step-by-step explanation:
40=16-8r
Subtract 16 from both sides.
24=-8r
Now divide by -8
-3=r
Answer:
-3= r
Step-by-step explanation:
40= 16- 8r
subtract 16 from both sides
40-16= 16 - 16 -8r
24= -8r
divide both sides by -8
24/-8 = -8r/-8
-3= r
h(x) = x2 + 1 k(x) = x – 2 (h – k)(3) =
Answer:
3x^2 - 3x - 3
Step-by-step explanation:
Plug in the equations in place of the variables
First, subtract k(x) from h(x)
x^2+1-x-2 (combine like terms)
x^2 - x -1
Next, multiply the new equation by 3
3(x^2 - x - 1) Use distributive property
= 3x^2 - 3x - 3
Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks.
How many weeks does it take her to have $250 in her bank account?
O 15 weeks
O 4.6 weeks
O 10 weeks
O 5.4 weeks
Answer:
10 weeks
Step-by-step explanation:
20x+50=250
First subtract 50 from both sides, which gives you 20x=200
then divide 20 from both sides which gives you x=10

Hi can someone tell me how is the answer 113?? how do i type it in the calculator?? im confused can someone please explain ASAP!!!!!!!!
THANK YOU
You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113

60 and 108 The GCF IS
Answer:
Greatest common factor (GCF) of 60: 223
Greatest common factor (GCF) of 108: 22333
The Greatest Common Factor (GCF) is: 2 x 2 x 3 = 12
Step-by-step explanation:
To get the Greatest Common Factor (GCF) of 60 and 108 we need to factor each value first and then we choose all the copies of factors and multiply them.

12 more than quotient of a number k and 5
Answer:
(k/5)+12 represents the question described
The required equation is 12 + k/5.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given statement is,
12 more than quotient of a number k and 5
Converting them into numerical form,
quotient of a number k and 5 = k/5
Therefore 12 more than quotient of a number k and 5 is written as,
12 + k/5
this is the required equation for the given statement.
Thus, the required equation is 12 + k/5.

How much salt is in a mixture containing 10 gallons of an 11% salt solution and 6 gallons of a 7% salt solution?
I think I can solve it but forming the equation is where I have problems.
Answer:
Step-by-step explanation:
There really isn't an equation because there isn't an unknown. If we create a table, the "equation" that you are talking about will be come apparent. Let's call the 2 solutions Sol 1 and Sol 2:
Gallons of solution * % salt = Gallons of salt
Sol 1
Sol 2
If we fill in this table according to the info we are given, we have 10 gallons of the 11% solution, and 6 gallons of the 7% solution, so
Gallons of solution * % salt = Gallons of salt
Sol 1 10 .11 = 1.1 gallons of salt
Sol 2 6 .07 = .42 gallons of salt
We multiply the Gallons of solution by the % salt to get the gallons of salt. There are 1.1 gallons of salt in solution 1 and .42 gallons of salt in solution 2, so in the mixture (which is 16 gallons) there is 1.1 + .42 gallons of salt, which is 1.52 gallons of salt.

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.
Answer:
10.8
Step-by-step explanation:
E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...
6 × 1.8 = 10.8 = G
__
If you like, you can write an equation relating G to E:
E = kG
10 = k(6)
k = 10/6 = 5/3
Now for E = 18, we have ...
18 = (5/3)G
18(3/5) = G = 10.8

Answer:
[tex]x_1=-\frac{3}{2} \\\\x_2=-1[/tex]
Step-by-step explanation:
the general fromula is
[tex](ax+b)(cx+)d)\\\\=acx^{2} +(ad+bc)x+bd[/tex]
so we need that
[tex]ac=2\\\\ad+bc=5\\\\bd=3[/tex]
for ac = 2
we only have 2 and 1
so let's say
[tex]a=2\\\\c=1[/tex]
so we now have
[tex](2x+b)(x+d)\\\\2x^{2} +(2d+b)x+bd\\\\[/tex]
and for bd = 3
we only have 3 and 1
but we need to
2d +b = 5
so we can have
b=3
and
d=1
so the factorized form is
[tex](2x+3)(x+1)[/tex]
so we come back to
[tex](2x+3)(x+1)=0[/tex]
so here we have two cases
Case 1
[tex](2x+3)=0\\\\2x+3=0\\\\2x=-3\\\\x=-\frac{3}{2}[/tex]
Case 2
[tex](x+1)=0\\\\x+1=0\\\\x=-1[/tex]
so those are our solutions
