Step-by-step explanation:
=9x+2(2x+3)
=9x+4x+6
=13x+6 I hope so,
Answer:
74.82
Step-by-step explanation:
48+38=86 86 X 0.87= 74.82
The answer is B
the steps are these
interchange the x and y variables
x=5y-8
solve for y so we get
y = x+8
----
5
First one: x>5
second one: x≥5
im pretty sure its right
Hope this helps love! :)
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
