Answer:
Firstly Substitute y=2x-5 into 5x-4y=-10
This will be 5x-4(2x-5)=10 now solve for x
5x-8x+20=-10
-3x=-30
X=10
Now sub x as 10 into the second equation y=2x-5
Y=2(10)-5
Y=15

Why?
<em>The Galaxy S10 has a 6.1-inch screen that's slightly larger than the iPhone 11 Pro's 5.8-inch display. It's also sharper than Apple's iPhone, or at least it should be on paper. ... But having a higher resolution doesn't always mean one screen is better than the other.</em>
Answer:
A) Divide 20 by 2 and then add 8 to the result
Step-by-step explanation:

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.
