T= trumpets
S= saxophones
T= s-10
S= 3t
Solve for t first in first equation by substituting the second equation into the first equation like this .
T=3t-10
T-3t=10
-2t=10
T=10/-2
T=5
Now substitute your t answer to second equation to find s .
S=3(5)
S=15
So you have 5 trumpets and 15 saxophones .
I hope this helps

Answer:
- 1 cm to 40 m
- 1/40 cm to 1 m
Step-by-step explanation:
The problem statement isn't clear as to which unit is 1 in your unit rate. If it is 1 cm, you can find the unit rate by multiplying the reationship by 4:
... 4 × (1/4 cm to 10 m) = 1 cm to 40 m
If it is 1 m, you can find the unit rate by multiplying the relationship by 1/10:
... 1/10 × (1/4 cm to 10 m) = 1/40 cm to 1 m
_____
<em>Additional comment on the problem</em>
Ordinarily, drawing scales are expressed as a fraction. Here, that would be ...
(1/4×1/100 m)/(10 m) = 1/4000 . . . or . . . 1 : 4000
The graph that would easily allow us to see the increase or decrease of persons or individuals owning cellphone/s from 2000 to 2007, we could use bar graph. This bar graph represents the grouped data in rectangles and the number in y-axis would be shown to differ through the lengths of the bars.
Find attached a graph that I constructed.
To do that graph I used Excel.
First I did a table with this set of points:
<span><span><span>height presuure
</span>
<span>
miles psi
</span>
<span>
0
14,7
</span>
<span>
<---- initial data
3.6 7.35
</span>
<span>
<--- increase hegiht 3.6 miles => half pressure
7.2
3.675
</span>
<span>
<---- second increase of 3.6 miles in height
10. 8
1.8375
</span>
<span>
<---- third increase of 3.6 miles in height
14.4
0.91875
