Help meeeeeeeeeeeee Find b; A=1/2h(b+B)

Mathematics

Start by multiplying everything out on the right side.
A=1/2hb+1/2hB

Move things around so that you get the clump with "b" in it alone on a side.
A-1/2hB=1/2hb

Start to isolate b.
(A/h)-1/2B=1/2b
(2A/h)-B=b

The answer is b=(2A/h)-B. You don't need the parenthesis, just put the thing in the parenthesis into one fraction.

Hope this helps!

Given AC with A(3, 4) and C(-9, -2), if B
babymother [125]

Answer:

B = (- 4, \frac{1}{2} )

Step-by-step explanation:

Using the Section formula

x_{B} = \frac{7(-9)+5(3)}{7+5} = \frac{-63+15}{12} = \frac{-48}{12} = - 4

y_{B} = \frac{7(-2)+5(4)}{7+5} = \frac{-14+20}{12} = \frac{6}{12} = \frac{1}{2}

Thus coordinates of B = (- 4, \frac{1}{2} )

The admission to a local fair is $10 for each adult and $6 for each child. Each ride costs $1.50 for an adult and $1 for a child
S_A_V [24]
So first start out by writing an expression for the cost of the child and the adult separately.

Child:
6 + 1r   ($6 + $1 per ride)

Adult:
10 + 1.5r   ($10 + $1.50 per ride)

to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:

10 + 1.5r - (6 + 1r)  just simplify this

For Part B, use your equation from part A where r = 7
