Answer:
x = 5
Step-by-step explanation:
1. Distributive Property
(Do what's in the parenthesis first)
4x - 2x + 6 = -4 + 5x - 5
2. Combine Like Terms
2x + 6 = -9 + 5x
3. Take away 6 on both sides
2x + 6 - 6 = -9 - 6 +5x
It will give u.....
2x = -15 + 5x
4. Subtract 5x on both sides
2x - 5x = -15
It will give u.....
-3x = -15
5. Divide by -3 on both sides to isolate the variable
-3x / 3 = -15/-3
Now you get....
x = 5
2 negatives make a positive
Thats ur answer
Hope this helped!
I'm assuming you have the octagonal base flat on the ground/floor. If so, then the horizontal cut through the center would basically cut the prism into two smaller equal pieces. Each piece will have the same octagonal base, but now the height is half as much. The cross section is the same as the base.
One way to picture it is to imagine you had a single room house with a very tall ceiling. Now place a floor between the top and bottom, midway through, so that you divide this house into too stories (each story being the same height). This new floor is a cross section, which is identical to the original floor of the house. Instead of a rectangular floor, picture the floor shape being an octagon.
<h3>Answer: Octagon</h3>
1. 28/15 as a decimal is <span>1.86666666666667
2.
</span><span>the number is divisible by 3. </span>
<span>Additionally, we know 120,000 is divisible by 3, 18,000 is divisible by 3, 420 is divisible by 3, and 15 is divisible by 3.
I hope this helps! I didn't do the last one my friend did but he thinks it's right. Please correct me if wrong.</span>
0.46666666666666. its a repeating decimal. or you could write it as 0.47.
Answer:
a= 
or ≈ -3.66
Step-by-step explanation:
-(3a+4)=7
-3a-4=7
<em>Add 4 to both sides</em>
-3a=11
<em>Multiply both sides by -1</em>
3a= -11
Divide both sides by 3
a=
