Answer: 397
Step-by-step explanation:
8x8=64
3x3=9
18x18=324
324+64+9= 397
Given data:
The given biology percentage is B=40%.
The given chemistry percentage is C=24%.
The percenage of earth science as compare to physics is E=P+4%.
The expresion for the sum of all subjects is,
B+C+E+P=100%
40%+24%+E+P=100%
E+P=36%.............................(I)
Substitute given value in the above expression.
P+4%+P=36%
2P=32%
P=16%
The nummber of students assigned earth science is,
E=16%+4%
=20%
Thus, the percentage of the students assigned to the physics subject is 16%.
From reading the problem we see that y = 0 and x = 16.
To find the correct equation, simple plug in the values for x and y for each equation and see which equation is true.
The correct answer is 5x + 4y = 80
5(16) + 4(0) =80
80 + 0 = 80
80 = 80
A) slope is 7 for 1 and -7 for the other. These lines intersect in 1 point only
b) both equations have slope -2/3 and the same intercept, so it is really only one line...infinite solutions
c) parallel lines have 0 solutions
Answer/Step-by-step explanation:
3:2 = 6:4 = 15:10

3 ÷ 2 = 1.5
6 ÷ 4 = 1.5
15 ÷ 10 = 1.5
