Answer:
A.105°
Step-by-step explanation:
Angle at W and V are equal and the angles at T and U are also equal
Hence taking angles at T and U...so as to calculate the value of x
5x + 15 = 3x + 21
5x - 3x = 21 - 15
2x = 6.....hence, x = 3
Then for the angle of VXU;
All angles in a triangle add up to 180°
15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU
180 - 75 = 105°
You would need to know the cost of the box of 20, then you would divide the total cost by the number of pencils in the box. This would give you the cost of one pencil - which is the unit cost.
Example:
Lets say the box of 20 pencils cost $10.
Divide the total cost by the number of pencils:
10 / 20 = 0.50 - This means each pencil cost 50 cents, so the unit cost would be 50 cents per pencil.
X = 8y + 16
x -16 = 8y
(x -16)/8 = y
(x/8) - 2 = y
Hi! Can you post a picture of the rhombus plz? Thx!
( x-5)/-2=(x-1)/-3
Cross multiply
-3(x-5)=-2(x-1)
Distribute
-3x +15 = -2x +2
Add 2x to both sides
-x +15 = 2
Subtract 15 from both sides
-x = -13
x=13
