You could divide both sides by two to get a rectangle that is 75 by 200
Answer:
Given
no of Grade 6 students = 220
no of Grade 7 students = 40 more than grade 6 students
Step-by-step explanation:
boys Grade 7 students = no of Grade 6 students - 40 more than grade 6 students
boys Grade 7 students = 220 - 40
boys Grade 7 students = <u>180 grade 7 boy students are enrolled</u>
Therefore, 180 grade 7 boy students are enrolled.
Answer: There are 20 goats and 18 chikens.
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
If the number of chickens is represented by C, and the number of goats is G.
Total of Animals equation:
a)C+ G = 38
Total of legs equation (since chickens have 2 legs and goats have 4 ):
b)2C + 4 G =116
If we multiply a) by 2 and subtract a) from b).
<em>2C + 4 G =116
</em>
<em>-
</em>
<em>2C + 2 G =76
</em>
<em>_________
</em>
<em>2G = 40
</em>
G = 40/2
G= 20
Replacing the value of G on any equation:
a) C+ (20) =38
C =38-20
C=18
There are 20 goats and 18 chickens.
Answer:
there is no difference between the two because the first equation answer is -3 but there is no answer to the second equation because both of the numbers doesn't have a factor of 12
Step-by-step explanation:
Answer:
1:200
5.6 cm^2 : y (as actual area)
y = 200 mutifly 5.6 cm^2
y= 1120 cm^2
We know 1m =100cm
so, 1m^2 =100cm x 100 cm = 1000cm^2
y= 1120 m^2/ 100x100
= 0.112 m^2
