Answer: x = 6
Step-by-step explanation: To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is -3x.
Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.
Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have <em>x</em>. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.
Answer: $300
Step-by-step explanation: You can think of this problem this way: If Micah saves a multiple of five dollars, his parents give him double that amount. So, if Micah saves $150, his parents give him double of that, or $300. Lucky Micah!
Answer:
length: 5 yd
width: 4 yd
area: 20 yd^2
Step-by-step explanation:
1 yd = 3 ft
15 ft * (1 yd)/(3 ft) = 5 yd
12 ft * (1 yd)/(3 ft) = 4 yd
A = LW
A = 5 yd * 4 yd = 20 yd^2
I’m so sorry I would try my best to answer but I can’t :(
Hey!
-----------------------------------------------
A pentagon needs 540 degrees in total to be a complete pentagon.
-----------------------------------------------
Solution:
Add all angles.
121 + 108 + 102 + 100 = 431
Subtract to 540.
540 - 431 = 109 degrees.
-----------------------------------------------
Answer:
x = 109 degrees
