Answer:
z=kx/y
zy=kx
zy/x=kx/x ( divided both side by x. to find k)
k=zy/x
k=6×4/3(z=6,y=4,x=3)
k=24/3
k=8
so z=kx/y
z=8×5/2(replace the numbers in the place of variables,k=8,x=5,y=2)
z=40/2
z=20

Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps. (10 points)
Answer:
is the missing number
Step-by-step explanation: The missing number would have to determine what the ineqaulities are
Hope this helps
Answer:
The number of candy packages is going to be represented by the variable c.
6.50 – 5.75
18 – 6.5 - 1.15c ≥ 5.75
11.5 - 1.15c ≥ 5.75
Subtract 11.5 from both sides
-1.15c ≥ -5.75
Divide both sides by -1.15 and flip the sign.
You answer be c ≤ 5

A taxi service charges a flat fee of $1.25 and $0.75 per mile. If Henry has $14.00, which of the following shows the number of miles you can afford to ride in the taxi?
Answer:
The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,
1.25 + 0.75x = 14
Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 miles.

PLEASE HELP NOW ASAP Peyton is collecting data on the lunch habits of students at Nicholas Orem Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Nicholas Orem Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
1000 students buy a lunch
Step-by-step explanation:
14 bring lunch
20 buy lunch
There are 34 kids in the sample class (14 + 20)
14/34 = .412 = 41.2%
There are 1700 students.
14 / 34 = x / 1700 cross multiply
14 (1700) = 34x
23,800 = 34x Divide each side by 34
23800/34 = 34x/34
23800/34 = x
700 = x
So 700 students bring a lunch.
1700 - 700 = 1000
1000 students buy a lunch.

Enter your answer as a mixed number in simplest form in the box.
v =
Answer:
The solution is: v = [tex]9\frac{1}{2}[/tex]
Step-by-step explanation:
Given equation is:
[tex]\frac{4}{5}(v-7) = 2[/tex]
The given equation is a linear equation in one variable. The solution requires isolating v on one side of the equation. Simple equality properties can be used to solve the equation.
So,
Multiplying both sides of equation with 5
[tex]5*\frac{4}{5}(v-7) =5* 2\\{4}(v-7) = 10[/tex]
dividing both sides by 4
[tex]\frac{4(v-7)}{4} = \frac{10}{4}\\v-7 = \frac{5}{2}\\[/tex]
Adding 7 on both sides
[tex]v-7+7 = \frac{5}{2}+7\\v = \frac{5+14}{2}\\v = \frac{19}{2}\\v = 9\frac{1}{2}[/tex]
Hence,
The solution is: v = [tex]9\frac{1}{2}[/tex]

.A length, originally 9cm, is increased so that the ratio of the new length to the old length is 13:3. What is the new length
Answer:
The new length is 39 cm
Step-by-step explanation:
We will use the ratio method to solve the question
∵ A length, originally 9cm, is increased
∴ The original length = 9 cm
∵ The ratio of the new length to the old length is 13 : 3
→ That means the ratio is ⇒ New : Original is 13 : 3
∴ The ratio New : Original = 13 : 3
→ By using the ratio method
→ New : Original
→ 13 : 3
→ x : 9
→ By using cross multiplication
∵ x × 3 = 13 × 9
∴ 3x = 117
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{117}{3}[/tex]
∴ x = 39
∵ x represents the new length
∵ x = 39
∴ The new length is 39 cm
In Buffalo New York the temperature was 10f in the morning if the temperature rose 10f what is the temperature now? Use a vertical number line to find the number.
Answer:
The temperature now is 20°F
Step-by-step explanation:
The given parameters are;
The initial morning temperature in Buffalo New York = 10°F
The rise in temperature in Buffalo New York = 10°F
The current temperature in Buffalo New York = The initial morning temperature in Buffalo New York + The rise in temperature in Buffalo New York
∴ The current temperature in Buffalo New York = 10°F + 10°F = 20°F.

Answer:
87.5
Step-by-step explanation:
2 inches is 70 miles. .5 inches is 17.5 and add them together and you get 87.5.
Please mark brainliest.
Answer: D. 87.5 miles
Step-by-step explanation:
They have given us a scale that 1 inch = 35 miles.
Since the distance is 2.5 inches, we have to multiply 2.5 inches by 35 miles.
1 in. = 35 miles
2.5 in = x
2.5 times 35 = 87.5 miles

Rectangle WXYZ will be dilated by a scale factor of 12, creating rectangle W'X'Y'Z'.
What will be the perimeter of rectangle W'X'Y'Z'?
1. 4 Units
2. 6 Units
3. 12 Units
4.24 Units
Answer:
12
Step-by-step explanation:
A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up, what is the measure of W'X'Y'?
A. 108 degrees
B. 98 degrees
C. 92 degrees
D. 88 degrees
Answer:
C. 92 degrees
Step-by-step explanation:
Given that the [tex]\angle{wxy}=[/tex]92° which is one of the angles of the quadrilateral WXYZ
The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.
The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.
So,[tex]\angle{w'x'y'}= \angle{wxy}[/tex]
By using the given value,
[tex]\angle{w'x'y'}=[/tex] 92°
Hence, option (C) is correct.
Rotating and translating quadrilateral WXYZ would not change its angle measure.
The measure of W'X'Y is (c) 92 degrees
The given parameters are:
[tex]\mathbf{WXY = 92^o}[/tex]
Translation and rotation are rigid transformations, and they do not alter the angle measure of the shape being transformed.
This means that: angles WXY and W'X'Y are congruent
i.e.
[tex]\mathbf{WXY = W'X'Y}[/tex]
So, we have:
[tex]\mathbf{W'X'Y = 92}[/tex]
Hence, the true option is (c) 92 degrees
