Step-by-step explanation:
2 gallons are needed for 10 galloms of lemonade
X / x + 5 = 8 / 12
x / x + 5 = 2 / 3
3x = 2(x + 5)
3x = 2x + 10
x = 10
Check:
x / x + 5
10 / 10 + 5
10 / 15
2 / 3 :)
Answer:
the area of the bed = 150 feet^2
the volume the soil holds = 27 feet^3
Step-by-step explanation:
the area of the bed = 25*6=150 feet^2
the volume the soil holds = 25*6*1.8=27 feet^3
Answer:
Solution given:
letA=(10,-4)
B=(-2,-4)
centre[C](h,k)=![\frac{10-2}{2},\frac{-4-4}{2}=(+4,-4)](https://tex.z-dn.net/?f=%5Cfrac%7B10-2%7D%7B2%7D%2C%5Cfrac%7B-4-4%7D%7B2%7D%3D%28%2B4%2C-4%29)
radius=

we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
(x-4)²+(y+4)²=36
or.
x²-8x+16+y²+8y+16=36
x²-8x+8y+y²=36-32

Do you mean to the nearest ten? If so, then it would be 60. Look to the right of the number you are to round, if it's 5 or more then round up. If it's 4 or less then round down. If it's a zero, then do nothing. The numbers following the one you are rounding get changed to zero's.
