Answer:
The expression for two times the difference of 4 and a number is

Step-by-step explanation:
To Find:
Write an expression for Eight times the difference of 4 and a number.
Solution:
Let the Unknown number be 'd'
Difference of 4 and d = ( 4 - d )
So One Time Difference of 4 and d = 1× ( 4 - d )
∴ Two Times Difference of 4 and d = 2× ( 4 - d )
∴ Eight Times Difference of 4 and d = 8× ( 4 - d )
The expression for Eight times the difference of 4 and d. will be

The expression for Eight times the difference of 4 and a number is

Answer:
Step-by-step explanation:
two angles are said to be supplementary if their sum is 180 degrees
Hence <1 + <2 = 180
Given
<1 = 28
Required
<2
Substitute into the formula
28+<2 =180
<2 = 180-28
<2= 152
Hence the measure of <2 is 152 degrees
Answer:
after 10 weeks.
Step-by-step explanation:
750 - 50x = 250
-50x = 250 - 750
-50x = -500
x = -500/-50
x = 10
