which had a purchase price of $80,500.
Which other car tax & price
varies directly with hers?
A) Purchase Price = $68,000 & Tax = $1,020
B) Purchase Price = $92,000 & Tax = $2,760
C) Purchase Price = $75,000 ¢ Tax = $1,350
D) Purchase Price = $85,000 & Tax = $2,040
Answer: D. Purchase Price = $85,000 & Tax = $2,040
Step-by-step explanation:
From the question, Sarah paid $1,932 in tax on her new car which had a purchase price of $80,500. The constant of proportionality here will be:
= $80500 / $1932
= 41.67
The options that varies directly with the above will be:
A. Purchase Price = $68,000 & Tax = $1,020
Constant of proportionality
= $68000 / $1020 = 66.67
B) Purchase Price = $92,000 & Tax = $2,760
Constant of proportionality:
= $92000 / $2760
= 33.33
C) Purchase Price = $75,000, Tax = $1,350
Constant of proportionality:
= $75000 / $1350
= 55.56
D) Purchase Price = $85,000 & Tax = $2,040
Constant of proportionality:
= 85000 / 2040
= 41.67
Based on the calculation, we can see.that option D has thesame constant of proportionality with the figure calculated.

Answer:
[tex]3x-4y[/tex]
Step-by-step explanation:
[tex]2x+x-4y[/tex]
If a term doesn't have a coefficient , it is considered that the coefficient is 1
[tex]2x+1x-4y[/tex]
Why is it considered that the coefficient is 1?
Remember that any term multiplied by 1 remains the same:
[tex]1.x=x[/tex]
Step 1
The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:
[tex]x=1 . X \\[/tex]
Step 2
Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:
[tex]x=1x[/tex]
That is why we can write the term without the coefficient as a term with coefficient 1.
Let's go back to your problem now
Collect like terms by adding their coefficients

A recipe uses 1/3 cup of flour and 1/8 cup of sugar.How much flour and sugar does the recipe use altogether?
Answer:
11/24
Step-by-step explanation:
Just add 1/3 and 1/8 to get the answer. To add or subtract any pair of fractions they must have the same denominator. To change them, find the least common multiple of the two denominators (3 and 8). The least common multiple of 3 and 8 is 24. Now multiply the denominator by a number that’ll make it into the least common multiple. The 3 in 1/3 should be multiplied by 8 to make it into 24. The 8 in 1/8 should be multiplied by 3 to make into 24. The number that you use to multiply each denominator should also be used to multiply the numerator of that fraction. 1/3 for example, becomes 8/24. 1/8 becomes 3/24. Finally add the numerators of both numbers and keep the same denominator which equals 11/24.

The formula a subscript n = 10 - 4n describes an arithmetic sequence. What are the first four
terms in the sequence?
A)6, 2, -2,-6
B) 6,2,0,-2
C)10, 6, 2,-2
D)14, 18, 22, 26
Answer:
A)6, 2, -2,-6
Step-by-step explanation:
a(n) = a +(n-1)d
a(n) = a +dn-d
a(n) = a-d + dn
a(n) = 10 - 4n
So d=-4
to get a: (a-d)=10
a=10-4=6
The first four terms:
a(1) = 6 +(1-1)-4=6
a(2) = 6 +(2-1)-4=2
a(3) = 6 +(3-1)-4=-2
a(4) = 6 +(4-1)-4=-6
it will be A

Graph a line that contains the point (6,-5) and has a slope of -2/3
Answer:
The line to graph is y=-[tex]\frac{2}{3}[/tex] -1
Step-by-step explanation:
In order to graph the line, it needs to be in slope-intercept form. We can make an equation in slope intercept form by using the point-slope form, which is y-y₁=m(x-x₁).
1. Plug info into point-slope form:
y-(-5)=-[tex]\frac{2}{3}[/tex](x-6)
2. Simplify:
y+5=-[tex]\frac{2}{3}[/tex] x+4
3. Simplify even further:
y=-[tex]\frac{2}{3}[/tex] -1
To graph the line, make a point a (0,-1). From here, go down 2 points and to the right 3 points. Continue the pattern and connect the points with a line.

Answer: 108
Step-by-step explanation: The equation to find the surface area of a square pyramid is s^2+2*s*l.
The area of the square base is equal to s2
The area of one triangle is equal to (s × l)/2
The slant height of a square pyramid equals (l)
Since there are 4 triangles, the area is 4 × (s × l)/2 equals 2 × s × l
Therefore, the surface area, call it SA is Surface Area (SA)= s2
+ 2 × s × l
so if you plug in the numbers you get 6^2+2*6*6 which equals 108
Answer:
The Answer is 108 feet squared.
Square Surface Area-
A= LxW
A= 6x6
A= 36
Triangle Surface Area-
A= 1/2 bh
A= 1/2 6x6
A = 1/2×36
A= 18
Since there are 4 Triangle multiple 18×4= 72
so... 72+36= 108

Three positive integers have a mean of 4 and a range of 7. Find the three numbers.
The three positive integers are estimated as (6, 1, 5), (6, 2, 4), (6, 3, 3), (5, 1, 6), (5, 2, 5), (5, 3, 4).
What is defined as the positive integers?Positive integers are integers that would be on the right side of 0 on a number line. These integers have a value greater than zero.
Natural numbers are another word for positive integers.Natural numbers are positive counting numbers (1, 2, 3, 4,...). The whole numbers are obtained by adding the number 0 to the natural numbers (0, 1, 2, 3, ...). Integers include 0 as well as the natural numbers and their inverses: (..., -3, -2, -1, 0, 1, 2, 3, ...).Now, as per the given question;
Let the three number be a, b and c.
The range of the number are given as 7.
Then,
(0 < a < 7), (0 < b < 7) and (0 < c < 7)
The mean of the number is defined as 4.
Thus,
(a + b + c)/3 = 4
So, (a + b + c) = 12.
Now, apply the Enumeration method;
Case 1: If a = 6 (a < 0), then (b + c) = 6. This, is possible for the set,
a = 6, b = 1 and c = 5. ora = 6, b = 2 and c = 4. ora = 6, b = 3 and c = 3.Case 2: If a = 5 (a < 7), then (b + c) = 7. This is possible for the set,
a = 5, b = 1 and c = 6. ora = 5, b = 2 and c = 5. ora = 5, b = 3 and c = 4.Therefore, the given three positive integers could be;
(6, 1, 5), (6, 2, 4), (6, 3, 3), (5, 1, 6), (5, 2, 5), (5, 3, 4).
