Answer:
24 pounds
Step-by-step explanation:
Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.
So, we can formulate the following equations:
X + Y = 60
X + (1/4)*Y = 33
Subtracting the second equation from the first one, we have:
3/4 * Y = 27
Y = 27 * 4 / 3 = 36
Now, we can calculate X:
X + 36 = 60
X = 24 pounds
Answer:
x=7
Step-by-step explanation:
The given equation is:
Multiplying both sides by LCM of 3 and 6
So,
Hence, the solution of the equation is x=7 ..
-50-15n =g(n-)+
-50. -50
-15n=g(n-)50
-15. -15
N=g(-15n)50
Answer:
6
Step-by-step explanation:
Draw line segments ST and RQ. Triangle RUQ and SUT are similar, because they are in a circle. Now, you use similar triangles to get that QU/UT=RU/SU so 2 = 12/SU so SU = 6, or y = 6.
Note: This is generealized by the Power of a Point, which states that if you have two chords that intersect, then you can do the same thing and it will show that QU*SU=RU*TU. (You can change the variables but the similar triangles stay the same).
