<h3>Simplifying </h3>
9x + -31 = 43
<h3>Reorder the terms:</h3>
-31 + 9x =43
<h3>Solving</h3>
-31 + 9x =43
<h3>Solving for variable 'x' .</h3><h3>Move all terms containing x to the left, </h3>
Add '31' to each side of the equation .
0 + 31 +9x = 43 + 31
<h3>Combine like terms: </h3>
-31 + 31 =0
0 + 9x = 43 +31
9x = 43 + 31
<h3>Combine like terms:</h3>
43 + 31 =74
9x = 74
<h3>Divide each side by '9'</h3>
x = 8. 222222222
<h3>Simpifying</h3>
x = 8.222222222
<span>If Dingane has $8.00, and thirty percent of that money is from five cent coins, then 8 x 0.3 = $2.40 of Dingane's money is made of five cent coins. In this case the number of five cent coins is the number of cents divided by five: 240/5 = 48. Therefore, Dingane has forty-eight five-cent coins.</span>
Answer:
The price of a sandwich is £2.5 and the price of a croissant is £2
Step-by-step explanation:
Let s be the number of sandwiches and c be the number of croissants
Then according to given statements the equations will be:

Multiplying equation 1 by 2 and subtracting equation 2 from the new equation

Now

Putting s=2.5 in equation 1

Hence,
The price of a sandwich is £2.5 and the price of a croissant is £2
Hello,
y=(x-2)²-15
y=5x-1
==> 5x-1=x²-4x+4-15
==> x²-9x-10=0
Δ=9²+4*10=11²
x=(9+11)/2 or x=(9-11)/2
==>(x=10 and y=5*10-1=49) or (x=-1 and y=5*(-1)-1=-6)
1) A (-1,-6)
2) C (10,49)
