Find the value of a and b

andriy [413]

Answer:

a = 133 degrees

b = 78 degrees

Step-by-step explanation:

the top and bottom lines are parallel.

the two sidelines are lines that intercept the top and bottom lines.

as they intercept parallel lines, they actually must have the same angles with them.

so, the 47 degrees inner angle at the bottom line, must be also somewhere at the interception point with the top line. and right, it must be now mirrored the outward angle at the top line. and that means a (the inward angle at the top line) is also the outward angle at the bottom line.

the sum of inward and outward angles at a point must always be 180 degrees.

so, the outward angle of 47 = the inward angle a =

= 180 - 47 = 133 degrees.

similar in the other side.

102 is the inward angle.

the outward angle of that is 180 - 102 = 78 degrees.

and that is also the inward angle b.

b = 78 degrees

Solve: -8(x - 3) + 5x < 9(x + 12) This is Algebra 1

Flauer [41]

Answer:

x>−7

Step-by-step explanation:

left side:

-8(x-3)+5x

distribute -8 into (x-3)

-8x+24+5x

combine like terms

-3x+24

right side:

9(x+12)

distribute 9 into (x+12)

9x+108

-3x+24<9x+108

Subtract 24 on both sides

-3x< 9x+108-24

combine like terms

-3x<9x+84

Subtract 9x on both sides

-3x-9x<+84

combine like terms again

-12x<84

Multiply both sides by -1 (reverse the inequality)

(-12x)(-1)>84(-1)

12x>-84

divide both sides with 12

$\frac{12x}{12}>\frac{-84}{12}$

x>−7

hope this helps

The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m

amm1812

Answer:

%82.5

Step-by-step explanation:

The final exam of a particular class makes up 40% of the final grade
Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

$FG=0.40*FE+0.60*0.45$ ,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

$\frac{ FG-0.60*0.45}{0.40}=FE$ .

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

$FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825$

That is, he need al least %82.5 to obtain a passing grade.
