How do you write The difference between 7 and the product 3x is 23
3x -7 =23
Answer:
B = (A - 6) / 10
Step-by-step explanation:
This problem has 2 variables and 1 equation so it is not trivial to solve with confidence the value of B; however, we can solve for B in terms of A. With that being said, let's start.
If A divided by B = 10:
A/B = 10
10 remainder of 6
Could also be written as 10 & 6/B since B is the divisor. Rewrite this, you can get the equation:
A/B = (10B + 6) / B
A = 10B + 6
A - 6 = 10B
B = (A - 6) / 10
Thus, you have solve B in terms of A.
Cheers.
Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 
)x + 
= 30 +
(x - )² = 
Take the square root of both sides
x - = ± 
= ± 
Add to both sides
x = ± , thus
x = - = - 5
x = + = 6
X=-16
X/2+6=-2
Subtract 6 from both sides
X/2=-8
Multiply by 2
X=-16
