Answer:
7 students play an instrument.
Calculation:
35=100%
20%=[20×35]÷100
=7
Step-by-step explanation:
2/3 X = 2x -24
now just solve for X.
2X = 8X - 72
-6x = -72
X = 12
1/2 (Base x height) = area
1/2 (4*x)=10
2x=10
X=5
The height is 5 units
y=mx+b
first find the y intercept or b or x=0
b=5
now find the slope
y²-y¹/x²-x¹--> 5-2/0-(-2)
m=3/2
the equation is D. y=3/2x+5
