Answer:
36%
Step-by-step explanation:
Jeans: 14
Shorts: 9
Capris: 2
Total number of students = Number of Jeans + Number of Shorts + Number of Capris
Total number of students = 14 + 9 + 2 = 25
% of students wearing shorts = Number of shorts / Total number of students * 100
% of students wearing shorts = 9 / 25 * 100 = 0.36 * 100 = 36%
The slope of y=9x is 9/1 which simplifies to 9
The slope of y=10x-2 is 10/1 which simplifies to 10
X2+y2=65............1
X2-3y=37..............2
÷both equation. 1 by 2
X+y=32,5
X=32,5-y......... 3
Sub 3 in 2
(32,5-y)2-3y=37
65-2y-3y=37
65-5y=37
-5y=37-65
-5y= - 28 divide both sides by - 5
Y=5,6........ 4
Sub 4 in 3
x=32,5-y
=32,5-5,6
=26,9
Hope it's the way you wanted it
Answer:
x = 15
Step-by-step explanation:
given that y varies directly with x
mathematically we can express this as
y = k x , where k is a constant
step 1: find k
given x = 3 and y = 21
y = k x
21 = k (3)
k = 7
hence the equation becomes
y = 7 x
when y = 105,
105 = 7x
x = 105 / 7 = 15
I think that it would be the first one A
