Step-by-step explanation:
[tex]\frac{5}{6}m+12-\frac{2}{3}-6[/tex]
*Note that [tex]-\frac{2}{3}[/tex] is equivalent to [tex]-\frac{4}{6}[/tex]*
[tex]Step\ 1\ \frac{5}{6}m+12-\frac{2}{3}m-6 \\\\[/tex]
[tex]Step\ 2\ \frac{5}{6}m-\frac{2}{3}m+12-6 \\\\[/tex]

Questions:
1. In which step did the student make her first error?
Explanation: The students made her first error in Step 3 because she multiplied the fractions, instead of subtracting them.
2. Write the correct expression for this step
The correct expression for Step 3:
[tex]Step\ 2\ \frac{5}{6}m-\frac{2}{3}m+12-6\\\\[/tex]
[tex]\frac{5}{6}m-\frac{4}{6}m+12-6\\\\[/tex]
[tex]\frac{1}{6}m+12-6\\[/tex]
[tex]\frac{1}{6}m+6[/tex]
Explanation: First, I converted [tex]-\frac{2}{3}[/tex] to [tex]-\frac{4}{6}[/tex]. Then subtracted the fraction. After, I subtracted the number (integers).

The length of a cell phone is 1.81.8 inches and the width is 4.84.8 inches. The company making the cell phone wants to make a new version whose length will be 1.621.62 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
Answer: 4.32432 inches
Step-by-step explanation:
This is a simple ratio problem:
we are given the old dimensions:
L x W = 1.818 x 4.848
new = 1.62162 x ?
? = (1.62162 x 4.848)/1.818 = 4.32432
The width of the new phone should be 4.32432 inches

Answers
Given:
∠A = 50°In the diagram given, we can tell that:
∠A and ∠B are a linear pair.∠B and ∠C are a linear pair.This means that:
∠A + ∠B = 180°∠B + ∠C = 180°Step-1: Find ∠B.
∠A + ∠B = 180°=> 50 + ∠B = 180°=> ∠B = 180 - 50=> ∠B = 130°Step-2: Find ∠C.
∠A = ∠C (Vertically opposite angles=> ∠C = 50°∠A+∠B = 180° [Linear pair]
50+ ∠B = 180°
∠B = 180-50

Answers
Answer:
7.5 hrs.
Step-by-step explanation:
First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]
y = mx + b
y = 17.7x + b
I will be using (4, 70.80) to find the value of b
(4, 70.80)
y = 17.7x + b
70.80 = 17.7(4) + b
70.80 = 70.80 + b
-70.80 -70.80
0 = b
y = 17.7x + b ==> y = 17.7x + 0 = OR y = 17.7x (since the value of b is 0)
The question wants us to find out how long it took Magan to make $132.75
y = 17.7x
132.75 = 17.7x
/17.7 /17.7
7.5 = x
This means that it took him 7.5 (seven and a half) hours to make $132.72
