The 2nd option is the answer :)!
Step-by-step explanation:
x - y + 5z = 29
y + 2z = 4
z = 7
since z = 7 we can use this value in second equation
y + 2×7 = 4 and y = -10
now we know the value of y we can solve the first equation
x -(-10) + 5×7 = 29
x + 10 + 35 = 29
x = -11
Answer:
length is 28.86ft
width= 4.12ft
Step-by-step explanation:
<h2>
This problem bothers on the mensuration of solid shapes, a rectangular prism.</h2>
The storage space takes the shape of a rectangular prism, and we are required to find the width and length of the storage space.
let the width of the basement be "w"
Given data
volume v=
length l = 
width w= 
height h= 
We know that the expression for the volume of a rectangular prism is

substituting our data we have to find "w"

dividing both sides by 35 we have

find the square root of both sides we have

since we know that length= 7w and width = w , we can substitute our value for w and find the length and width

<em>Answer:</em>
<em>38%</em>
<em>Step-by-step explanation:</em>
<em>60 percent girls</em>
<em>50 percent of girls walk</em>
<em>50 percent take the bus</em>
<em></em>
<em>40 percent boys</em>
<em>20 percent walk</em>
<em>80 percent take the bus</em>
<em></em>
<em>If there are 100 people in the school</em>
<em>60 girls</em>
<em>30 girls take the bus</em>
<em></em>
<em>40 boys</em>
<em>8 boys walk</em>
<em></em>
<em>8+30=38</em>
<em>38% of the people walk to school</em>
