Answer:
p+33+p-19+2p-46=180
Step-by-step explanation:
Add all your variables and all your numbers and then simplify
Set up a proportion: 5/14=25/x and you know 25=5*5 so you do the same to the bottom 14*5=70 so the shadow of something 25 feet high is 70 feet long.
Answer: 70 feet
Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: . In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.
Note:
I used 3.14 for (pi).

Answer:
Step-by-step explanation:
do yo want it as a decimal or a fraction?
Start by solving for x in the first problem:
3x=3+9y
x=1+3y
Then plug that into the second equation:
6(1+3y)-3y=-24
6+18y-3y=-24
15y=-30
y=-2
Then plug that back into first equation:
3x-9(-2)=3
3x+18=3
3x=-15
x=-5
Then I would check your answer by plugging those into both equations:
3(-5)-9(-2)=3
-15+18=3
3=3 CHECK
6(-5)-3(-2)=-24
-30+6=-24
-24=-24 CHECK
So the answer is x=-5 y=-2
