Answer:
There are 392 students in the seventh grade.
Step-by-step explanation:
Let us assume that there are x number of students in the seventh grade.
Now, 3/8 of the seventh grade students were taking Advanced math at the beginning of the year, but seven dropped out by the end of the year.
So, after the end of the year there were
number of students taking advanced math.
So, as per given condition, 
⇒ 
⇒ x = 392
Therefore, there are 392 students in the seventh grade. (Answer)
A, C and E all work in the equations. In order for them to work, you must use the ordered pair in each of the three situations. Below is the work for all of the correct answers.
Ordered Pair A : (1, -1)
y < x + 1
-1 < 1 + 1
-1 < 1 (TRUE)
y < 4
-1 < 4 (TRUE)
x < 6
1 < 6 (TRUE)
Ordered Pair C : (4, 2)
y < x + 1
2 < 4 + 1
2 < 5 (TRUE)
y < 4
2 < 4 (TRUE)
x < 6
5 < 6 (TRUE)
Ordered Pair E : (4, -2)
y < x + 1
-2 < 4 + 1
-2 < 5 (TRUE)
y < 4
-2 < 4 (TRUE)
x < 6
4 < 6 (TRUE)
Answer:
<em>The field is 1 and 4/10 mile long.</em>
Step-by-step explanation:
If I understand the question:
(1/2) + (9/10) =
(5/10) + (9/10) = (14/10)
(14/10) is 1 and 4/10
The field is 1 and 4/10 mile long.
Answer:
x-3
Step-by-step explanation:
(x
2
−9)=(x−3)(x+3)
(x
3
−27)=(x

−3x+9)
(x

−8x+15)=(x−3)(x−5)
∴ H.C.F. of (x

The value of the ratio of skateboards wheel in its simplest form is <u>1:4</u>.
<h3>What is the ratio?</h3>
The ratio refers to the numerical relationship between two variables.
Ratios show the quantity of one variable contained in another.
Ratios are expressed in fractions, decimals, or percentages. They can also be written using the ratio symbol (:).
The total number of skateboards = 12
The total number of wheels = 48
The ratio value of skateboards wheels = 48:12
= 4:1 or 1:4
Thus, we can conclude that for every skateboard, there must be 4 wheels, given their ratio values.
