Answer:
so, lauren isn't correct
Step-by-step explanation:
3x + 4 (2x + 5) = 6x + 5x + 5
3x + 8x + 20 = 11x + 5
11x + 20 ≠ 11x + 5
Answer:it is neither accurate nor precise
Step-by-step explanation:
Answer:
y = 26
Step-by-step explanation:
The angles of a linear pair total 180°.
__
(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°
7y -2 = 180 . . . . . . divide by °, collect terms
7y = 182 . . . . . . . . add 2
y = 26 . . . . . . . . . divide by 7
_____
<em>Additional comment</em>
The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
Answer:
The percentage decrease from the first week to the third week is 25 %
Step-by-step explanation:
The number of popcorn bags sold on the first week = 500 bags
The second week, they sell 50% more than the first week
So, the number of bags sold on the second week is
= 500 + 50% of 500
=
= 
= 500 + 250
= 750 bags
The third week, they sold 50% less than the second week
So, the number of bags sold on the third week is
= 750 - 50% of 750
= 
= 
= 750 - 375
= 375 bags
Now the percentage decrease from the first week to the third week is
=
= 
= 
= 25 %
Answer: B. 1/2(y - 116) = 64
Step-by-step explanation:
Since, we know that,
The angle formed by two tangent =
= 
Here, Major arc = y°
Minor arc = 116°
And, Angle made by two tangents YX and YZ,

( because,
)
⇒ 
Which is the required equation to find y, the measure of XWZ.
Thus, Option B is correct.
