Answer:
23.7%
Step-by-step explanation:
In order to solve this, we need to find the total expenses as well as the amount of money spent on housing.
The total expenses are simply the sum of the prices of all the items listed under "expenses":
1080 + 385 + 200 + 970 + 230 + 128 + 145 + 210 + 400 + 0 + 410 + 300 + 100 + 0 = $4558
The amount of expenses on housing is $1080. So, divide this by the total and multiply by 100:
(1080 / 4558) * 100 = 23.7%
He is correct because the equation would be 10/1 X 1/10 so it would multiply to 10/10 when simplifies it would be 10
Functions A and B have the same y- intercept
The two sides stemming from the vertex A, are both equal, each one is 25 units long, since the triangle has twin sides, that means is an "isosceles" triangle.
Now, the twin sides, make twin angles at the base, namely at BC.
and running the angle bisector AD, will not only cut the ∡A in two equal halves, but will also cut the segment BC into two equal halves. Because the bisector is perpendicular to the base.
all that rant.... simply means that BD = DC or 3x + 4 = 4x - 5.
9 = x.
how long is BC? well since BC = BD + DC, then 3(9) + 4 + 4(9) - 5.
First, you should combine the x terms:
-3x - 7 = 29
Then, get rid of the negative 7, by adding 7 to both sides.
-3x = 22
Finally divide 22 by -3, to solve for x.
x = -22/3 or -7.33
