You have an 91 average in a class, the grade is split between coursework worth 30% of the grade,
tests worth 20% of the grade, finals worth 20% of the grade, reinforcement worth 15% of the grade
and participation worth 15% of the grade. If you have a 99 average for final, a 99 average for tests, a
91 average for your participation, and a 95 average on reinforcement what is your coursework
grade?

5x+10 is the correct one

hope this

inch

step-by-step explanation:

yard and mile are too big.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
