Hey there!

0.7(x- 9) - 0.9(-9) = (-0.2) + 1.8 \\ Distribute: 0.7(x) + 0.7(-9) =(-0.2) + 2 \\ 0.7(x) = 0.7x \\ 0.7(-9) = -6.3 \\ -0.9(-9) = 8.1 \\ 0.7x + (-6.3) +8.1= -0.2+ 1.8 \\ LikeTerms: 0.7x , \\ -6.3 , 8.1 \\ -0.2,1.8 \\ 0.7x + (-6.3) + 8.1= (-0.2) +1.8 \\ Subtract: 1.8 \\ 0.7x + 1.8 -18 \\ = 1.6-1.8 \\ = 0.7c = -0.2 \\ \\ Divide: 0.7 \\ \frac{0.7x}{0.7}  = \frac{-0.2}{0.7}  \\ \\ \\ \\ Answer: x = -0.285714

nikitadnepr [17]

Total number of campers = 20

Total number of teams = 5

⇒ Number of campers in each team = Total number of campers ÷ Total number of teams

⇒ Number of campers in each team = 20 ÷ 5

⇒ Number of campers in each team = 4

Number of recorders in each team = 1

⇒ Number of searchers in each team = Number of campers in each team - Number of recorders in each team

⇒ Number of searchers in each team = 4  - 1

⇒ Number of searchers in each team = 3

Hence, there will be 3 searchers in each team

Please Help! :( Segment TQ is 26 units long. What is the length of QV? 8 units 26 units 31 units 32 units
WINSTONCH [101]
<h2>Answer</h2>

The length of QV is 31 units

<h2>Explanation</h2>

Notice that triangle STR and triangle TQR are congruent by Side-Angle-Side, so ST = TQ

We also know that TQ = 26, and we can infer from our diagram that ST = 3x+2, so let's replace the values:

ST = TQ

3x+2=26

3x=24

x=\frac{24}{3}

x=8

Also, notice that triangle SVR is congruent to Triangle VQR by Side-Angle-Side as well, so QV = SV

We know that SV=4x-1, so let's replace the value:

QV=4x-1

Since we know that x=8, we can replace the value to find QV:

QV=4x-1

QV=4(8)-1

QV=32-1

QV=31
