As with any "solve for ..." problem, you start by looking at the operations performed on the variable of interest. Here, when you evaluate this expression according to the order of operations, you
- add b1
- multiply by (h/2)
When you want to solve for b2, you undo these operations in reverse order. To undo multiplication by a fraction, you multiply by the inverse (reciprocal) of the fraction. To undo addition, you add the opposite.
Whatever you do must be done to both sides of the equation.
Here we go ...
... (2/h)A = b1 + b2 . . . . . we undid the multiply by h/2, by multiplying by 2/h
... (2/h)A - b1 = b2 . . . . . we undid the addition of b1 by adding the opposite of b1
Then your solution is
... b2 = 2A/h - b1
If you want to, you can combine these terms over a single denominator to get
... b2 = (2A -h·b1)/h
I think is 3 because a gues need tu multiplay so i gues the anwsar y 3
Hello!
We have to use a certain formula to find the area of a parallelogram. The formula is:
A = bh
Since we already have the area and the base of the parallelogram, we will be able to find the height!
Notice how we multiply the base by the height to find the area? Well, we'll have to do the opposite to find one of its dimensions.
What's the opposite of multiplication? Division!
Formula for base:
B = A ÷ h
Substitute:
B = 60 ÷ 5
B = 12
ANSWER:
The base is 12 feet long.
Good Day!
Answer:
(-3,-2)
Step-by-step explanation:
2x-5y=4
3x-7y=5
solve the equation
x=2+5/2y
3x-7y=5
substitute the value of x into an equation
3(2+5/2y)-7y=5
multiply 3 to 2. and. 3 to 5/2y
6+15/2y-7y=5
minus 6 to 5 and. add 15/2y to -7y
-1/2y=1
divide both sides by -1/2
y= -2
substitute the value of -2 into an equation
x=2+5/2•(-2)
multiply 5/2 to -2
x=2+-5
add but since 5 is negative then subtract the numbers
x= -3
combine y= -2 and x= -3 as a point
So the answer is (-3,-2)
The height of the deck if it is parallelogram H ≈ 6.13
