I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>
First you had to calculate with parenthesis first.

Then you add and subtract from left to right.

Final answer 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

Subtracting a positive number from a positive number......this is normal subtraction
Answer:
The slope of a horizontal line is zero
Step-by-step explanation:
All horizontal lines are parallel to the x-axis.
The x-axis has a zero slope.
All parallel lines have the same slope.
Therefore the slope of a horizontal line is zero.
This means there is no rise in y.
So rise over run will become:
0/run=0
Answer:$105
Step-by-step explanation:
I think but the way I done it was a 100 *1+5
The definition of parallel lines is;<span> two </span>lines<span> that are always the same distance apart and never touch. In order for two </span>lines<span> to be </span>parallel<span>, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. ... Any </span>line<span> that has the same slope as the original will never intersect with it.</span>
