Answer:
b= -164
Step-by-step explanation:
calculate the difference
7x(-75)-2b= -197
multiply the numbers
-525-2b= -197
move the constant to the right- hand side and change the sign
-2b= -197+525
add
-2b=328
divide
b= -164
Answer:

Answer: x=3
Step-by-step explanation:
4(2x-7)-2x=-10
Multiply 4 with 2x and -7
8x-28-2x=-10
Add like terms which are 8x and -2x
6x-28=-10
Add 28 to both sides so the -28 cancels out
6x=18
Divide both sides by 6 to isolate the x
Answer= x=3
Answer:
Option (2)
Step-by-step explanation:
Radius of the circular base of the cone = 
Given in the picture,
Diameter of the circular base = 8 cm
Height of the cone = 6 cm
Therefore, radius of the cone = 
= 4 cm
Option (2) will be the correct option.
1. Moved the decimal on both sides
2. The equation became 78.6/2
3. Divided 7/2, got 3
4. Divided 8/2, got 9
5. Put the decimal point on the preferred spot
6. Divide 6/2, got 3
7. 78.6/2 equals 39.3
