Answer:
16 and 2
Step-by-step explanation:
I'm not sure honestly if this is correct, but I hope this helps.
Answer: The answer is 80 mph.
Step-by-step explanation: 1. Divide 14 from 571.
2. You'll get the answer 40. So it's 40 mph.
3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)
Applying precedence of operations, the result of the expression is of 161.
<h3>What is the precedence of operations?</h3>
Power operations are done before multiplication/division, which are also done before addition/subtraction.
Operations inside brackets or parenthesis also take precedence.
In this problem, the operation is:
[3 x 2^5 + 13 x (-2)] + 7[8 - (4 - 9)]
First the power:
[3 x 32 + 13 x (-2)] + 7[8 - (4 - 9)]
Now the multiplications on the first bracket, and the subtraction on the second:
[96 - 26] + 7[8 - (-5)]
Then, applying the parenthesis to the negative number, we have that:
[96 - 26] + 7[8 - (-5)] = 70 + 7 x 13 = 161.

For the answer to the question above, a system of equations has no solution when the lines representing the equation are parallel but do not coincide. For two lines to be parallel, the must have the same gradient i.e. coefficient of x when y is made the subject of formula must be equal.
If one of the equations is
y = 8x + 7,
then the other equation will be
y = 8x - 7
