Answer: x=3
Step-by-step explanation:
<u> 1 </u>(x-15)+2x=16
3
<u> 1 </u>x-15+2x=16
3
<u>x-45+2x=16</u>
3
x-15+6x=16
7x=15+16
x=<u> 21 </u>
7
x=3
3 -

=

- 7
First, simplify

to

/ Your problem should look like: 3 -

=

- 7
Second, simplify

to

/ Your problem should look like: 3 -

=

- 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:

= b
Ninth, simplify

to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18
Answer:
b = 18
What you need to do is divide 32 by 40 so you end up with 1%. Then you need to multiply that by 25 and you will get 25%
32÷40=0.8
0.8x25=20
From the least to greatest from the fractions are: -1/19, -4/7, and 7/4.
And the answer is D.
When going from the bottom corners, the one going from left to right has a positive slope of 1/2, and the side going from right to left has a negative slope of 1/2. That is the slope of the side of the triangle and that slope makes the most sense in this situation.
