Answer: The equation would NOT help us solve for the length and width of the classroom is "
".
Step-by-step explanation:
Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .
Given ,
The perimeter of a rectangular classroom floor is 90 feet.
The length of the floor is twice the width.
i.e. Length =2 (width)
i.e. x= 2y ..(i)
Also, perimeter = 2(length+width)
When we put value of x from (i), we get
Hence, the equation would NOT help us solve for the length and width of the classroom is "".
Answer:
y = 1/2x + 1
Step-by-step explanation:
m = 1/2
Slope-intercept:
y - y1 = m(x - x1)
y - 3 = 1/2(x - 4)
y - 3 = 1/2x - 2
y = 1/2x + 1
The second one is correct and the first is incorrect so far but let me see if the other two are
Answer:
The driveway of the brown house is longer by 5 feet.
Step-by-step explanation:
Given two houses (red and brown) such that:
- The driveway in front of the brown house is 35 feet long.
- The driveway in front of the red house is 7 yards and 9 feet long.
We want to determine which of the houses has a longer driver.
To compare, we must ensure that all units are the same.
Therefore: 7 Yards =3 X 7 feet =21 feet
Driveway of the red house =7 yards and 9 feet long=21+9=30 feet
Therefore:
- The driveway in front of the brown house is 35 feet long.
- The driveway in front of the red house is 30 feet long.
The driveway of the brown house is longer by 5 feet.
14 2/5 segments
24 divided by 3/5 doesn’t work so you have to multiply them
24 x 3/5 = 14 2/5
