Answer: A because that’s what makes the most sense
Answer:
4y( 4xy + 7x +2)
Step-by-step explanation:
16xy^2+28xy+8y
16xy^2 =2*2*2*2*x*y*y
28xy = 2*2*7 *x*y
8y = 2*2*2*y
The common factors are 2*2*y = 4y
2*2*2*2*x*y*y + 2*2*7 *x*y+2*2*2*y
2*2*y( 2*2*x*y + 7 *x+2)
4y( 4xy + 7x +2)
So we know that the word 'product' means multiplication, and that means that h and 4 are being multiplied. Also, one-fifth of x is another way of saying that one-fifth is being multiplied with x. So then we can construct the equation:
And we can then simplify this by taking out the multiplication sign:
And so since we do not know what x or h is equal to, this is as far as we can go.

Step-by-step explanation:
(5)
Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and
∠ABC + ∠CBD = ∠ABD, that is
2x + 3x - 10 = 90, simplifying
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20, thus
∠ABC = 2x = 2 × 20 = 40°
∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°
(6)
4x - 18 = 3x + 7 ( vertical angles are congruent )
Subtract 3x from both sides
x - 18 = 7 ( add 18 to both sides )
x = 25
7y = 5y + 28 ( vertical angles are congruent )
Subtract 5y from both sides
2y = 28 ( divide both sides by 2 )
y = 14
Cost Price for oil change =$27
Charge for the customers =$40
Markup cost = Difference between selling price and cost price =$40-$27=$13
To find the percent of markup, divide the markup cost by the cost price and multiply it by 100.
Markup percent = (13/27)*100
=48.15%
