mart [117]

Explanation:

This question's it's about the order of operations. P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right.

Do exponents first.

$5^2=5*5=25$

$25-4*6+11$

Then, multiply left to right.

$4*6=24$

$25-24+11$

And add/subtract left to right.

$25-24=1$

$1+11=12$

$\boxed{=12}$

Hope this helps!

Thanks!

Have a great day!

Solve each system of equations by substitution:<br> X + Y = 75<br> 10x + Y = 48

Nimfa-mama [501]

Answer:

X= -3;

Y=78

Step-by-step explanation:

A: X+Y=75

B: 10X+Y=48

B-A: (10X+Y)-(X+Y)=48-75

10X+Y-X-Y= - 27

9X=-27

X= -3;

Now

A is : -3+Y=75

Y=75+3=78
