Let the number of pants have to be made be x.
So,
9.55 * x = 525.00
x =
≈ 54.97
Thus, the number of pants have to be made are 54.
So,
9.55 * x = 525.00
x =
Thus, the number of pants have to be made are 54.
X + y = 26 3x + y = 56 Please help me! Show Working Please

Step-by-step explanation:
(X + y = 26) (-3)
3x + y = 56
____________
- 3 x - 3y = - <u>78</u><u> </u><u> </u><u>Note</u>:cross <em>3x</em> and<em>-3x</em> from both equations (they're opposite)
3x +y =56
____________
-3y +y = - 78 +56
-2y = - 22
____________
So we replace y in eq 2: (to obtain x)
3x + 11 =56
3x =45
X =15

Answer:
Rabbit is faster than bear.
Step-by-step explanation:
Speed of rabbit or bear is determined by their rate of change of their distances with time.
The distance covered by rabbit in hours is given as:
The above equation is of the form , where,
is the rate of change of
with
.
Therefore, the rate of change of rabbit's distance with time is 30 mi/h.
Now, from the graph, the slope is given as the rise over run.
Rise is 50 miles and run is 2 miles.
So, rate of change of bear's distance with time is,
Now, 30 is greater than 25. So, rabbit is faster than bear.
