14. Question wise,
In ΔRST,
∠R=2x+5
∠S=x+1
∠T=7x-16
we know,
∠R+∠S+∠T=180 [sum of 3 angles of a triangle is 180°]
2x+5+x+1+7x-16=180
10x-10=180
10(x-1)=180
x-1=18
x=19
so,
∠R=(2×19)+5=43
∠S=19+1=20
∠T=(7×19)-16=117
15. Question wise,
In ΔABC,
∠A=∠C-13
∠B=4∠C-11
we know,
∠A+∠B+∠C=180 [,,]
∠C-13+4∠C-11+∠C=180
6∠C-24=180
6∠C=180+24
∠C=204÷6=34
so,
∠A=34-13=21
∠B=(4×34)-11=125
16. Question wise,
In ΔJKL
∠K=∠J+9
∠L=2∠J-21
we know,
∠J+∠K+∠L=180
∠J+∠J+9+2∠J-21=180
4∠J-12=180
4∠J=180+12
∠J=192÷4=48
so,
∠K=48+9=57
∠L=(2×48)-21=75

Answers
Answer:
46. or 45.5 if not rounded
Step-by-step explanation:
We know she makes $72.85 at selling cookies if she sales 17 cupcakes for $3.25 she'll make $55.25 but were trying to find how many she sales with $1.60 so $72.85 divided by 1.60 is 45.5 and if not then it's 46. rounded.

Sarah needs to lease out a music studio to record her new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The fixed fee to use the studio is $150 and the total cost charged for 2 hours is $300. Write an equation for P,P, in terms of t,t, representing the amount of money Sarah would have to pay to use the studio for tt hours.
Answers
Answer:
[tex]P=150+150t[/tex]
Step-by-step explanation:
Let P denotes the total cost and t denotes the time.
Total cost for 2 hours = $300
So,
Cost for 1 hour = [tex]\frac{300}{2} =\$150[/tex]
Also,
Fixed fee to use the studio = $150
The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio.
Therefore,
Total cost = Fixed fee to use the studio + Hourly fee for each hour in the studio
[tex]P=150+150t[/tex]

Step-by-step explanation:
If you show the answers I can tell you the exact answer.
Answer:
Please provide answer choices. As I have nothing to look off of, I cannot answer accurately. However, I can provide a definition to the word, "slope".
Explanation:
The equation for slope can most often be written out as y=mx+b, where m is the slope, and b is the intercept. The slope of a line is the number that shows the rise and run of the line.

Answer: -4c+12
all real numbers
Step-by-step explanation:
6) 28-(3c+4) =2 (c+6)+c
When there is a - in front of an expression in parentheses , change the sign of each term of the expression.
28-3c-4=2(c+6)+c
Distribute 2 through the parentheses
28-3c-4=2c+12+c
Now we do the same thing only different way
2(c+6)
Multiply each term in the parentheses by 2
2c+2×6
Multiply the numbers
2c+12
_____________
28-3c-4=2c+12+c
subtract the numbers
24-3c=2c+12+c
Collect like terms
24-3c=3c+12
It's the same thing only different way ok
2c+c
If a term doesn't have a coefficient , it is considered that the coefficient is 1.
2c+1c
Collect like terms by adding their coefficients
(2+1)c
Add the numbers
3c
________
24-3c=3c+12
Move variable to the left hand side and change its sign
24-3c-3c=12
Move constant to the right by adding its opposite to both sides
-3c-3c+24-24=12-24
eliminate the opposites
-3c-3c=12-24
Collect like terms
-6c=12-24
Calculate the difference
-6c=-12
so the same thing only different way ok
12-24
Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.
-(24-12)
Subtract the numbers
-12
__________
-6c=-12
divide both sides of the equation by -6
-6c÷(-6)=-12÷(-6)
Any expression divided by itself equals 1
c=-12÷(-6)
Dividing two negatives equals a positive
(-)÷(-)=(+)
c=12÷6
Calculate the quotient
c=2

Sorry this got to you super late. At least others looking for the answer can find it.
The proof by S A S congruence rule is given below.
Given from fig, JK || LM.
And JK = LM
Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.
So, angle KJL = angle MLN........equation 1
Also given L is the midpoint of JN so, JL = NL.....equation 2
Now, in triangle JLK and triangle LNM
JK = LM (given)
angle KJL = angle MLN (from 1)
JL = NL (from 2)
So by S A S congruence rule, triangle JLK conguent triangle LNM proved.

Which equation has a graph that is parallel to the graph of 2x − y = −1?
A. 2x + y = 8
B. y = −1/2x + 3
C. y − 1 = 2(x − 3)
D. y = −2x − 1
Answers
Answer:
B
Step-by-step explanation:
So from the first graphs equation is
2x-y=-1
therefore if we made y the subject of the formula, the equation would be
2x+1=y , this is also the same as y=2x+1
from this, the equation is clearly in the form y=mx+c so we can get the gradient
The gradient of graph one would be 2
The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2
Now we look at our options and see which one has the gradient as -1/2
Using linear function concepts, it is found that the equation parallel to 2x - y = -1 is given by:
C. y − 1 = 2(x − 3)
The equation of a line has the following format:
[tex]y = mx + b[/tex]
I n which m is the slope.If two lines are parallel, they have the same slope.The equation of the line given is:
[tex]2x - y = -1[/tex]
[tex]y = 2x + 1[/tex]
Which has slope [tex]m = 2[/tex]
If we look at option C:
[tex]y - 1 = 2(x - 3)[/tex]
[tex]y = 2x - 6 + 1[/tex]
[tex]y = 2x - 5[/tex]
It also has slope of [tex]m = 2[/tex], the same as the line given, thus, they are parallel.
