Answer:
x = 35
Step-by-step explanation:
Solve for x:
5 (x + 20) = 7 x + 30
Expand out terms of the left hand side:
5 x + 100 = 7 x + 30
Subtract 7 x from both sides:
(5 x - 7 x) + 100 = (7 x - 7 x) + 30
5 x - 7 x = -2 x:
-2 x + 100 = (7 x - 7 x) + 30
7 x - 7 x = 0:
100 - 2 x = 30
Subtract 100 from both sides:
(100 - 100) - 2 x = 30 - 100
100 - 100 = 0:
-2 x = 30 - 100
30 - 100 = -70:
-2 x = -70
Divide both sides of -2 x = -70 by -2:
(-2 x)/(-2) = (-70)/(-2)
(-2)/(-2) = 1:
x = (-70)/(-2)
The gcd of -70 and -2 is -2, so (-70)/(-2) = (-2×35)/(-2×1) = (-2)/(-2)×35 = 35:
Answer: x = 35

Answer:</h3>
4) ÷10
5) Yes
<h3>
Step-by-step explanation:</h3>
<em>Question 4</em><em>:</em>
Just take the first number 322 and plug in the choices.
At the end the only one that will finish with all exactly like the pattern is ÷10.
<em>Question</em><em> </em><em>5</em><em>:</em>
We know Logan's watch is still under warranty because,
1 week = 7 days.
6 weeks × 7 days = 42 days
But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.
