Answer:
m = 3
Step-by-step explanation:
BD is angle bisector of <ADE
so
<BDE= <ADB
6m - 3 = 15
6m = 18
m = 3
The length of the baby's head is 5.5 inches if the ratio of a baby's head length to the length of the rest of the body is 1:3.
<h3>What is the ratio?</h3>
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
At birth, the ratio of a baby's head length to the length of the rest of the body is 1:3.
A baby's total body length is 22 inches,
Let x be the head length
Let 3x be the
x + 3x = 22
4x = 22
x = 22/4 = 11/2 = 5.5 inches
Thus, the length of the baby's head is 5.5 inches if the ratio of a baby's head length to the length of the rest of the body is 1:3.

Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Students learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.
The student materials consist of the student pages for each lesson in Module 4.
The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
Answer:
None
Step-by-step explanation:
-4x-11=2(x-3x)+13
-4x-11=2x-6x+13
-4x-11=-4x+13
-11=13
Therefore, there are no solutions for the equation as both sides will never be equal to each other.
