Answer:
x = 1
Step-by-step explanation:
Given
5x - (4x - 1) = 2 ← distribute the parenthesis by - 1
5x - 4x + 1 = 2
x + 1 = 2 ( subtract 1 from both sides )
x = 1
In this triangle, we know base & perpendicular are 300 & 400 'cause 500 is the longest side which is hypotenuse
Now, Area of a triangle = ab/2 = (300)(400)/2 = 120000/2 = 60000
As cost for 1 ft² = $0.60
cost for 60000 ft² = 60000 * 0.60 = $36000
In short, Your Answer would be Option A
Hope this helps!
Answer:
<h2>B. 49,062.5 ft²</h2>
Step-by-step explanation:
The formula of an area of a circle:

r - radius
We have the diameter d = 250 ft. We know: d = 2r.
Therefore r = 250 : 2 = 125 ft.
Substitute:


$17.80 in 1 hr
$1 in 1/17.80 hr
$675.00 in 675.00/17.80 hr
37.9 hours
Which is 38 hours after rounding it.
Answer:
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
