Step-by-step explanation:
Statement. Reason
→ 9(x-6)+41 = 75. Transposing the like terms.
→ 9(x-6) = 75 - 41 Performing subtraction of the term in RHS
→ 9(x-6) = 34 Performing multiplication in LHS.
→ 9x - 54 = 34 Distributive property
→ 9x = 34 + 54 Performing addition of the term in RHS.
→ 9x = 88. Now, transpose 9 from LHS to RHS , it's arthmetic operator will get changed.
→ x = 88/9
Answer:
The measure of arc AC is 85°
Step-by-step explanation:
we know that
The inscribed angle measures half that of the arc comprising
so
m∠ABC=(1/2)[arc AC]
substitute
(4x-5.5)°=(1/2)[5x+25]°
(8x-11)°=(5x+25)°
8x-5x=25+11
3x=36
x=12°
Find the measure of arc AC
arc AC=(5x+25)°
arc AC=5(12)+25=85°
Answer:
The correct answer option is: Isabella should have divided the product of 
and 9 by 3 to get 
Step-by-step explanation:
We are given a diagram of a cone with height 
and area of the base (circle) 
.
Isabella uses the equation 
and we are to find the error that she is making in finding the volume of this cone.
The volume of a cone is given by: 
out of which 
represents the area of the base (circle).
Therefore, Isabella should have divided the product of and 9 by 3 to get .

Thats the answer in edgenuity student :)
The measures of the angles are 30, 60 and 90 degrees.
Explanation:
I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale factor
x
. And, the sum of the measures of the angles of a triangle is
180
.
