Answer:
x =27
Step-by-step explanation:
from Z angls rule the agle (BDE) =72
and total angl on D =180
so, 2x +2x+72=180
4x = 180 -72
4x = 108 (divied both sides by 4)
x= 27
X= 2.737 - look on the website "Tiger algebra for the answer by typing in the question
Answer:
She would need
flour to make
times the recipe.
Step-by-step explanation:
To make 1 recipe Amelia uses =
of flour.
So, to make
times the recipe she would need =
.
We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).


Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

So, she would need
flour to make
times the recipe.
The answer to this question is b
When something bisects an angle, it cuts that angle in half. This means that ray BD cuts angle ABC in half. Therefore, angle ABD, which is formed by cutting the angle in half, is equal to angle CBD, which is also formed by cutting the angle in half. Because of this, you have to set the equation equal to each other.
9x-18=5x+2
Combine like terms. Add 18 to both sides.
9x=5x+20
Combine like terms. Subtract 5x from both sides.
4x=20
Divide 4 on both sides.
x=5 degrees
