<h3>
Answer: B) no solutions</h3>
===========================================================
Explanation:
Let's isolate the variable y in the first equation
-2x - y = 1
-2x = 1 + y
1+y = -2x
y = -2x-1
Then we'll plug this into the second equation
-4x - 2y = -1
-4x - 2(-2x-1) = -1
-4x + 4x + 2 = -1
0x + 2 = -1
0 + 2 = -1
2 = -1
We run into a contradiction. No matter what x value we pick, the last equation will never be true. This leads to a domino effect to cause the first set of original equations to never be true when considered as a system.
Therefore, this system is inconsistent. There are no solutions. These two lines graph out parallel lines that never intersect.
The cost of gas bill including VAT is 379.26.
<h3>What is VAT?</h3>
Value-Added Tax (VAT) is a tax, which is payable on sales of goods or services within the territory of the Member States of the EU.
Given:
Cost of the gas before the VAT was added was £361.20.
VAT = 5%
Thus, cost of bill including VAT is
=361.20.*1.05
=379.26.

Let x be the <span>length of each of two congruent sides.
</span>The triangle will be аcute if:
x² + x² > 8²
2x² > 64
x² > 32
x > √32
x > 5.657
So, the smallest possible length of one of two congruent sides have to be 5.7 cm (<span>to the nearest tenth)</span>
Answer: 30
Reason: you divide 60=2x which makes x=30
