Answer:
there are no solutions if two linear equations are parallel to each other.
*B. no sloution
Answer:
Option B: x = 15 is a solution, but x = 9 is not is the correct answer.
Step-by-step explanation:
Given equation is:
x - 3 = 12
The solutions we have to check are;
x = 9 and x = 15
Putting x = 9 in the given equation;
9 - 3 = 12
6 ≠ 12
Putting x = 15 in the given equation;
15 - 3 = 12
12 = 12
Hence,
Option B: x = 15 is a solution, but x = 9 is not is the correct answer.
Answer:
(-25 + 4 squared) x 7
( -25 + 16) x 7
-9 x 7
-63

Answer: 5894.2
Step-by-step explanation:
You'll want to follow PEMDAS to simplify this expression.
1.) P - Parentheses
2.) E - Exponents
3.) M - Multiplication
4.) D - Division
5.) A - Addition
6.) S - Subtraction
We'll start with what's inside the parentheses:
(2.4 × 1018) + (3.4 × 1015)
(2,443.2) + (3,451)
Now all you have to do is add the values together to get your answer!
2,443.2 + 3,451
5894.2
