In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,
![\frac{60}{58} =\frac{x}{609}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B58%7D%20%3D%5Cfrac%7Bx%7D%7B609%7D)
now, we can solve for x
we get
![x=609*\frac{60}{58}](https://tex.z-dn.net/?f=x%3D609%2A%5Cfrac%7B60%7D%7B58%7D%20)
we get
![x=630](https://tex.z-dn.net/?f=x%3D630%20)
so, students have another color hair in 8th grade is 630.........Answer
The value of x in the equation is 23.
<h3>How to solve equation?</h3>
46 / x = 2
The equation above have one solution because the value of x is a single value.
46 / x = 2
cross multiply
2x = 46
divide both sides by 2
2x / 2 = 46 / 2
x = 23
A value of x that makes an equation true is 23, which when substituted into the equation and simplified makes the equation turn into x = 23.
A value of x that makes an equation false is 46, which when substituted into the equation and simplified makes the equation turn into x = 46.

Answer:407%
Step-by-step explanation:
-1 for the last one all of them involve 3 and the 1 isn’t 3 so it would be -1 hahaha
According to graph, GMT time when the plane flew over the beacon was 9:24.
While looking closely at the graph on x axis , one will notice that each hour is divided into 5 parts and hence each part has 12 minutes. looking at y axis, one may find that each part on y axis resembles 20miles. Hence at 280 miles away from Bristol, The GMT time is 9:24.
<h3>What is a graph?</h3>
- In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.
- The relationships between two or more items are frequently represented by the points on a graph.
- The study of graphs, which are mathematical constructions used to represent pairwise relationships between things, is known as graph theory in mathematics. Vertices (also known as nodes or points) make up a graph in this sense, which are connected by edges (also called links or lines).
- Undirected graphs, in which edges connect two vertices symmetrically, are distinguished from directed graphs, in which edges connect two vertices asymmetrically. One of the main topics of study in discrete mathematics is graphs.
