A student wants to find point C on the directed line segment from A to B on a number line such that the segment is partitioned in a ratio of 3:4. Point A is at –6 and point B is at 2. The student’s work is shown.

C = (three-fourths) (2 minus (negative 6)) + (negative 6)
C = (three-fourths) (8) minus 6
C = 6 minus 6
C = 0
Analyze the student’s work. Is the answer correct? Explain.

No, the student should have added 3 + 4 to get the total number of sections, and used the fraction Three-sevenths instead of Three-fourths.
No, the student should have subtracted 2 from –6 to find the distance.
No, the student should have added 2 at the end to add to the starting point.
Yes, the student’s answer is correct

Answers

Answer 1

Answer:

Answer is A

Step-by-step explanation:

Took on Edge 2020

Answer 2

The student should have added 3 + 4 to get the total number of sections, and used the fraction three-sevenths instead of three-fourths.

Given the segment partitioned in a ratio of 3:4, the total ratio is expressed as:

Total = 3 + 4  = 7

If point C is on the line segment AB, hence the point C on the line will be expressed as:

[tex]C = \frac{3}{3+4} \cdot (2-(-6)+(-6))\\C= \frac{3}{7} \cdot (2+6-6)\\C= \frac{3}{7} \cdot (8-6)\\C=\frac{3}{7} \=(2)\\C=\frac{6}{7}[/tex]

Based on the calculation, we can conclude that the student's answer is incorrect. The student should have added 3 + 4 to get the total number of sections and used the fraction three-sevenths instead of three-fourths

2 Cassie has a family photograph that measures 5-inches wide and 7-inches long. She wants to enlarge the photograph and hang it on the wall. If the length of the enlarged photograph is 87.5 inches, what is the width of the enlarged photograph?

Answers

Answer:

62.5 inches

Step-by-step explanation:

We would solve this using ratio

Width : Length = Width/Length

For the Original photo

5 inches : 7 inches = 5/7

For the enlarged phots

x : 87.5 inches = x/87.5

Equating both ratios together, we have:

5/7 = x /87.5

Cross Multiply

7x = 5 × 87.5

7x = 437.5

x = 437.5/7

x = 62.5 inches

Hence, the width of the enlarged photo is 62.5 inches

Step-by-step explanation:

Given

Rule:

Output = Input + 3

Required

Complete the table

Represent the input with x and the output, y

So, the rule becomes

[tex]y = x + 3[/tex]

When Input = 1

[tex]x = 1[/tex]

[tex]y = x + 3[/tex]

[tex]y = 1 + 3[/tex]

[tex]y = 4[/tex]

This means:

Output = 4

When Input = 6

[tex]x = 6[/tex]

[tex]y = x + 3[/tex]

[tex]y = 6+3[/tex]

[tex]y = 9[/tex]

This means:

Output = 6

When output = 11

[tex]y = 11[/tex]

[tex]y = x + 3[/tex]

[tex]11 = x + 3[/tex]

[tex]x = 11 -3[/tex]

[tex]x = 8[/tex]

This means

Input = 8

So, the complete table is:

Joaquin is ordering 5 identical sandwiches and a bag of chips. The bag of chips cost $1.25 and the entire order costs $38.75. Write an equation you can use to find the price of the sandwhich. Let’s represent the price of the sandwhich.

Answers

Answer:

A sandwich costs $7.5

Step-by-step explanation:

Given

Represent chips with c and sandwiches with c

[tex]c = \$1.25[/tex]

[tex]Total = \$38.75[/tex]

From the question, we understand that 5 sandwiches were ordered.

Hence, the question of the system is:

[tex]5s + c = Total[/tex]

Substitute values for Total and c

[tex]5s + 1.25 = 38.75[/tex]

Collect Like Terms

[tex]5s = 38.75 - 1.25[/tex]

[tex]5s = 37.5[/tex]

Divide both sides by 5

[tex]s = \frac{37.5}{5}[/tex]

[tex]s = 7.5[/tex]
