Hey there!!!!
Given,
Angle r and angle s are supplementary angle.
And angle r = 120°.
Now, we have,
supplementary angle's sum is always 180°.
So, angle r + angle s = 180°.
or, 120°+ angle s = 180°
Therefore the measure of angle s is 60°.

What value of x is in the solution set of 9(2x+1) <9x-18?
Answer:
x = 0
Step-by-step explanation:
9(2x+1) < 9x - 18
Distribute the 9 through
18x + 9 < 9x - 18
Get like terms on the same sides
9x < -27
Divide both sides by the value in front of the x
x < -3
Hope this helps! :)

This is because by using y=mx+b and graphing the two equations you can find their intersection which is (10,60).
A number x is decreased by 40% then increased by 25% what is the final result In terms of x ?
Answer:
Step-by-step explanation:
Let your number be X. To increase X by 40% we can multiply it by 1.4, let's call this new number Y.
So Y = X * 1.4
Now to decrease Y by 40% we can multiply it by 1 - .4 = .6. Lets call this new number C.
So C = Y *.6 = (X * 1.4) * .6 = X * (1.4 * .6) = X * .84.
Therefore, C = .84 * X.
So we can see C is 84% of X, or 16% less than X.
Thus, if you increase a number by 40% then decrease it by 40%, the net percentage is -16% .
Final result in terms of 'x' will be → 0.75x
Conversion of verbal statement to algebraic expression: Select the variables given in the verbal statement first. Form the algebraic expression as per verbal statement given in the question.
Let the number = x
As per first statement → "A number 'x' is decreased by 40%"
Algebraic expression for the statement → (x - 40% of x)
→ (x - 0.4x)
→ 0.6x
Second statement → "Then increased by 25%"
Algebraic expression for the statement → (0.6x + 25% of 0.6x)
→ [tex](0.6x+\frac{25}{100}\times 0.6x)[/tex]
→ [tex](0.6x+0.15x)[/tex]
→ [tex]0.75x[/tex]
Therefore, final result in terms of x will be (0.75x).

Step-by-step explanation:
BC = 6x + 6,
AB = 8 +9, and
AC = 141.
Find BC
Answer: 60
Step-by-step explanation:
Since AB and BC creates AC, we can add them together to find x, then use that to find the value of BC.
8x+9+6x+6=141 [combine like terms]
14x+15=141 [subtract both sides by 15]
14x=126 [divide both sides by 14]
x=9
Now that we have found the value of x, we can plug that into BC.
6(9)+6 [multiply]
54+6 [add]
60
Now, we know the length of BC is 60.
Answer:
60

Bonnie ran a total of 18 miles over the course of 2 track practices. How many miles would Bonnie have run after 7 track practices? Solve using unit rates.
Answer:
63 miles
Step-by-step explanation:
Bonnie ran a total of 18 miles over the course of 2 track practices. How many miles would Bonnie have run after 7 track practices?
2 track practices = 18 miles
7 track practices = y miles
Cross Multiply
2 track practices × y miles = 18 miles × 7 track practices
y miles = 18 miles × 7 track practices/ 2 track practices
y miles = 63 miles.
Therefore, Bonnie will have run 63 miles after 7 track practices
