Answer:
92°Step-by-step explanation:
Sum of internal angles of a regular polygon is:
S = 180(n - 2)We have here 5-sided polygon:
S = 180*(5 - 2) = 180°*3 = 540°Now sum the given angles measures and solve for x:
3x + 1 + 2x + 15 + 3x - 10 + 3x - 8 + 5x - 2 = 54016x - 4 = 54016x = 544x = 544/16x = 34°Find the measure of angle R:
m∠R = 3x - 10 = 3*34 - 10 = 102 - 10 = 92m∠R = 92°DUE IN 10 MINS PLEASE HELP
what is the image of (-9,-1) after a dilation by a scale of 2 centered at the origin
30 points!! Find the value of x. Show yours steps.
Answer: x=10
Step-by-step explanation:
Supplementary angles 142+2(x+9)=180
Subtract 142 frrom both sides
2(x+9)=38
now distribute
2x+18=38
subtract again
2x=20
Divide both sides by 2
x=10

Is (2, 10) a solution to this system of equations?
y = 4x + 2
y = x + 8
Answer:
Yes, (2, 10) is a solution to this system:
y = 4x + 2
y = x + 8
Step-by-step explanation:
When graphed, the two equations cross at (2,10) making it a solution.
Answer:
Yes
Step-by-step explanation:
If y=4x+2 and y=x+8, then 4x+2=x+8
4x+2=x+8
4x=x+6
3x=6
x=2
Plugging this into the original equation "y=x+8", we obtain the result that y=10.
This means, (2, 10) is a solution to the system.

Answer:
y = 4/5x
y = 4/5x - 3.2
Step-by-step explanation:
The equation for slope is y=mx+b, the mx stands for the slope which is 4/5x. The b stands for where the line goes through the y axis, in this equation the first line crosses the y axis at the origin (0) and the second one crosses at -3.2, these are also called y-intercepts because they intercept the y axis.

Kallie drank 12.75 gallons of water in 3 weeks. She drank the same amount of water each day. Estimate how many gallons she drank in one day.
Answer:
607 miltliters per day
Step-by-step explanation:
Step one:
given data
Kallie drank 12.75 gallons of water in 3 weeks
if she drank the same amount each day, then in one day she will drink
Note----there are 31 days in 3 weeks (7 days make 1 week)
Step two:
Hence in one day she will drink
= total volume of water/number of days
= 12.75/21
=0.607liters per day
or
607 militliters per day

Can someone help (8th grade math)
Answer:542.5
Step-by-step explanation:
15x+y=25
solve for y
Answer:
y=25-15x (i hope it is right)
Answer: All you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). Keep in mind that these answers all mean the same thing and have that same value but they are in different forms.
Step-by-step explanation:
To isolate the y, subtract 15x from both sides of the equation (in order to keep the equation balanced). You should get 15x+y-15x=25-15x. Simplify and your equation will be y=25-15x. It could also be rearranged to be y=-15x+25. If you want to go a step further, you can factor out 5 from -1x and 25 to get y=5(-3x+5). Finally, if you wanted to go even further, you could factor out -5 to get y=-5(3x-5). So all you possible answer are y=25-15x, y=-15x+25, y=5(-3x+5), and -5(3x-5). I don't really know which form you need it in. Hope this helps!
There are 272 people in an audience. The ratio of adults to children is 5 : 3. How many are children? (please answer)
Answer:
There are 102 children
Step-by-step explanation:
Let us solve the question
∵ There are 272 people in an audience
∴ The total number of people = 272
∵ The ratio of adults to children is 5: 3
→ Find the sum of the two parts of the ratio
∴ The sum of the parts of the ratio = 5 + 3 = 8
→ By using the ratio method
→ Adults: Children: People
→ 5 : 3 : 8
→ A : C : 272
→ By using the cross multiplication
∵ C × 8 = 3 × 272
∴ 8C = 816
→ Divide both sides by 8
∴ C = 102
∵ C represents the number of children
∴ There are 102 children
