Answer:
<h2>x = 4</h2>
Step-by-step explanation:
In algebra, the goal is always to isolate the variable, so its value can be determined.
<h3>Step 1: Use distributive property</h3>
-8 = -x + -4
<h3>Step 2: Subtract -4</h3>
-4 = -x
<h3>Step 3: Multiply by -1</h3>
4 = x
<h3>Step 4: Check</h3>
-8 = -(4 + 4)
-8 = -8 ✔
<h3>Step 5: Answer</h3>
x = 4
I'm always happy to help :)
If you can't use a calculator or anything, just multiply 65 by 160 to get 10,400 and then move the decimal 2 places to the left. The answer is 104.
<u><em>Answer:</em></u>
- 84x - 70
<em><u>Step-by-step explanation:</u></em>
We want to combine like terms:
-10 - 90x + 6x - 60
We can see (-10) and (-60) are both regular constants so:
- 10 - 60 = - 70
Then (-90x) and (+ 6x):
6x - 90x = - 84x
- 84x - 70
Answer:
y = 40.
Step-by-step explanation:
The opposite sides of a cyclic quadrilateral sum to 180, so:
3y + 2y - 20 = 180
5y = 180 + 20 = 200
y = 40.
Answer:
4
Step-by-step explanation:
