Answer:
Step-by-step explanation:
X^2+7x+63=63
<=> x^2+7x=63-63=0
<=> X(x+7)=0
<=> x1=0
X2=-7
It gets repetitive really fast. The second verse is the same as the first. The result is ...
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%
Answer:
Step-by-step explanation:
The system of equations are expressed as
2x + 17y = −3 - - - - - - - - - 1
5x + 4y = 9 - - - - - - - - - - 2
In order to eliminate y, you will need to multiply equation 1 by 4 and equation 2 by 17. This would make them to have the same value of 68y.
You might choose to eliminate x instead. To do this, you will need to multiply equation 1 by 5 and equation 2 by 2. This would make them to have the same value of 10x.
