Answer:
<h2>2 (the answer should have a positive sign.)</h2><h2>The equivalent to -5-(-7) is -5+7.</h2>
Step-by-step explanation:
To solve this problem, use the order of operations.
PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
Add or subtract.
Solve.
So, the correct answer is 2.
Remember to follow PEMDAS, and left -> right rule.
First, solve the Parenthesis:
(4 + 2^3)
Solve the exponent.
2^3 = 2 x 2 x 2 = 4 x 2 = 8
4 + 8 = 12
_______________________________________________________________
(5^2) x (12)
5^2 = 5 x 5 = 25
25 x 12
_______________________________________________________________
Multiply
25 x 12 = 300
________________________________________________________________
300 is your answer

Answer:x=3 y=1/2
Step-by-step explanation:
x+2y=4
2x-2y=5
Add both equations together
x+2x+2y-2y=4+5
3x+0=9
3x=9
Divide both sides by 3
3x/3=9/3
x=3
Substitute x=3 in x+2y=4
x+2y=4
3+2y=4
Collect like terms
2y=4-3
2y=1
Divide both sides by 2
2y/2=1/2
y=1/2
Answer:15
Step-by-step explanation:
Angle F is equal to angle G so 5x + 18 = 7x-12 so you would solve for x which would equal 15
