Answer:
3
Step-by-step explanation:
2×-3y = 12 ( multiply whit 4)
3x + 4y =1 (multiply whit 3 )
8x -12y =48
9X+ 12y = 3
if you add this equations
17X =51
X= 51 / 17
x=3
The complete question in the attached figure
Part A) How much sand is currently in the container?
[sand currently in the container]=(5)*(4 1/2)*(2.25)-----> (5)*(4.5)*(2.25)
[sand currently in the container]=50.625 in³
the answer Part a) is 50.625 in³Part B) How much more sand could the container hold before?
[sand could the container hold before]=[5*4.5*3]-[50.625]
[sand could the container hold before]=[67.5]-[50.625]------> 16.875 in³
the answer Part B) is 16.875 in³
Part C) What percent of the container is filled with sand?
the volume of container is [5*4.5*3]=67.5 in³
the volume filled with sand=50.625 in³
therefore
if 100%----------------> 67.5 in³
X---------------------> 50.625 in³
X=(50.625*100)/67.5=75 %
the answer Part C) is 75%
The answer is 330. 67x5=335. Now round it.
Percentage change from 50 to 82, first, let's solve how much is added from 50 to 82.
=> 82 - 50 = 32
Now how many percent is 32 out of 50?
=> 32 / 50 = 0.64
=> 0.64 * 100% = 64%
thus 64% added or increased in the previous number.
