Answer:
to get x by itself so divide 5 by 2 and then add 7 to the other side
Step-by-step explanation:
2x-7=5
x-7=2.5
x=2.5+7
x=9.5
Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
Let's make the width 'x'.
And the length 'x+4'.
Perimeter is adding up ALL the sides.
Add: x + x + 4 + x + x + 4.
Simplify:
x + x + 4 + x + x + 4 = 4x + 8
The Answer Is B.
To Find The Mean, You Add Up Every Number And Divide By How Many Numbers There Were.
