Answer:
there are no expressions in the question, so I can't help you. Can you post the expressions?
1 yd = 3 ft
This means the unit cost per feet is $4.99/3.
Let 'x' represent the length of the material in feet that you can be with $30.
(4.99/3)*x <= 30
Formula for circumference of circle:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer: Circumference of the circle is 25.1 cm (Rounded to 1 decimal place)
1/6 is the simplest form for the fraction 5/30.
Answer:
Step-by-step explanation:
2x + 3y = 2
x = 2 - 3y /2
x + y = 0
substitute the value of x
+ y = 0
2 - 3y + 2y = 0
2 = y
again,substitute the value of y
x = 2 - 3y / 2
=2 - 3*2 / 2
=2 - 6 / 2
=-2
