Answer:
x = 2
Step-by-step explanation:
5x + 3 = 7x - 1
Subtract 3 to both sides
5x = 7x - 4
Subtract 7x to both sides
-2x = -4
Divide by -2 to both sides.
x = 2

To solve this problem you must apply the proccedure shown below:
1. You have the the<span> 13.5-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.
2. Then you have:
3</span>9 degrees 45'=39.75°
<span>
Sin(39.75°)=d/13.5
d=13.5x</span>Sin(39.75°)
<span> d=8.63
</span>
Answer:
D is correct
Step-by-step explanation:
The opposite of a negative number is the positive version of it which is 3.5 and the absolute value of a number is always the positive version of a number which would make it also 3.5. For example absolute value of -4 is 4 and absolute value of 5 is 5.
25/4= 6.25
In one day, there are 6.25 letters.
Hope this helps!
