If you would like to solve the equation y/9 + 5 = 0, you can do this using the following steps:
y/9 + 5 = 0
y/9 = -5 /*9
y = -5 * 9
y = - 45
The correct result would be D. y = - 45.
If you would like to solve - 282 - (+ 1,017), you can do this using the following steps:
- 282 - (+ 1,017) = - 282 - 1,017 = - 1,299
The correct result would be C. - 1,299.
Answer:
A
Step-by-step explanation:
34 square inches I think you just divide the number in half.
Step-by-step explanation:

we have a 1in : 0.2in scale of drawing to reality.
0.2 = 2/10 = 1/5
so, 1in in the drawing is actually 1/5in in reality.
how long are the 4in in the drawing ?
well, 4 times the 1in thing.
4×1/5 = 4/5 = 0.8in long
again the similar triangles
similar triangles means that each pair of corresponding lines (sides, heights, ...) in the triangles follows the same scaling factor for the length.
so, what do I need to multiply the side of the large triangle with to get the corresponding side length of the small triangle ?
27 × x = 9
x = 9/27 = 1/3
and that is the scale factor.
If you divide 4/5 you get 80%. Then if you divide 4/9 you get .4444444 which means Nicole's friend only ran 44% of Nicole's distance. That's what i got from there. You might have to multiply more, but that's all I've got from the information you gave me
