So the equation looks like this : 15*3x=78
subtract 15 from both sides: -15 -15
then divide by 3 from both sides
to isolate the variable: 3x=63
3/3x=63/3
x=21 (your mystery number is 21)
Answer:125
Step-by-step explanation:
x*25=125 x=125
I found the accompanying picture of this word problem.
The circle was inscribe in the triangle. The area outside of the circle but inside the triangle is the shaded area.
True. The shaded area of the following shape can be found by subtracting the area of the circle from the area of the triangle.
Answer:
f(x)^-1 = 
Step-by-step explanation:
f(x) = (4x - 3) / 7
y = (4x - 3) / 7
x = (4y - 3) / 7
x / 7 = 4y - 3
x/7 + 3 = 4y
y = 
Answer:probably x’s all of them
