Answer:
Hi again, I'm here to answer!
The correct answers:
10. x = -7 2/3
11. x = 2
12. x = 3
Step-by-step explanation:
(x + 3)/2 = (x - 4)/5
(5x + 15)/10 = (2x - 8)/10
3x/10 = -23/10
x = -23/3
x = -7 2/3
(2x - 1)/3 = x/2
(4x - 2)/6 = 3x/6
x/6 = 2/6
x = 2
(3x + 1)/5 = 2x/3
(9x + 3)/15 = 10x/15
-x/15 = -3/15
x = 3
Hope this helped!
Answer:
Step-by-step explanation:
187 divided by 7 is 6.5
Answer:
=−5x2+18x−13
Step-by-step explanation:
Let's simplify step-by-step.
x2−1−3(2x−2)(x−2)
Distribute:
=x2+−1+−6x2+18x+−12
Combine Like Terms:
=x2+−1+−6x2+18x+−12
=(x2+−6x2)+(18x)+(−1+−12)
=−5x2+18x+−13
Answer:
=−5x2+18x−13
The product of 
will be 
Given expression,
We have to find the product of
