Answer:
W=4h(11-j)/b-h
Step-by-step explanation:
Eliminate variables on the left side first.
b(h+w) = 4h (11-j) - so, divide b by both sides
(h+w)/b=4h(11-j)/b then, eliminate h by subtracting on both sides.
(h+w)-h=4h(11-j)/b - h (h is eliminated on the left side and now you are left with
W=4h(11-j)/b - h
To get from the first number to the second number the equation is 10x0.5+5=10
Thereafter the equation to get to the next number is 10x1.0+10=20
Thereafter the equation to get the next number is 20x1.5+15=45
Thereafter the equation to get the next number is 45x2.0+20=110
You can notice the pattern, the first number is what the last number was, you increase the second number by 0.5 and you increase the third number by 5.
Following this pattern to find the last number you do 110x2.5+25. This equation results in the number 300. Now time for the last number. You input 300x3.0+30. The answer results in 930. Therefore, the missing number is 930.
(1, 1), 5 + 2 = 7, not that hard!
Answer: 0.4
Step-by-step explanation: 3/4 - 1/3 = 5/12
converted to decimal: 5 ÷ 12 = 0.4
Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB 
units [By distance formula : 
]
units
Width = BC = 
units
Area = length x width
= 
Hence, the area of the rectangle is 82 sq. units .
