75%off.. she paid 4$ for the scarf. if 16 = 100% (divided by 4 is 25% ) 4×3= 12 which equals 75 %. im sorry for the lengthy explanation im sure there is an easier way to explain i hope u understand the point i was getting at. it is definitely 75% off though
I think the answer is 3. C= -3 and integer 2
The shortcut is if u have this brand calculator .. ‘ press mode, 5, 3 ‘....the quadratic calculator will appear and add the values to get whole numbers and not imaginary numbers ( i will be shown along with the numbers on the calculator )
Length: 21 meters
Width: 5.25 meters
<u>Scale changes to 1 cm : 9 cm</u>
- Length: 63 meters
- Width: 15.75 meters
New length is 3 times old length
Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
Answer:
The coordinate of point A is -138
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
In this problem
substitute
solve for x_2
therefore
The coordinate of point A is -138
