Answer:
x=50
See below for word problem.
Step-by-step explanation:
While shopping, you spend $125 before tax. You buy 3 dresses at the same price each and receive a $25 discount. How much is the price of each dress?
3x-25=125
3x=125+25
3x=150
x=50
A is not right. Half the cookie would have an angle of 180
B is not right. 4 pieces would have an angle of 288
C is correct. 360/5 is 72 degrees
D is not right. 2 pieces would have an angle of 144
E is correct 90<144 so a 90 degree angle would fit in 2 pieces
Obviously it will be 0.25.
Because this number is a rational number not a integer number....
We have the first equation:
-10x + 5y = zero
we can divide all terms by 5 to get:
-2x + y = zero
This means that:
y = 2x .................> equation I
We now will look at the second equation:
<span>-4x-6y=54
</span>we will substitute with equation I in this equation to get:
<span>-4x-6(2x)=54
-4x - 12x = 54
-16x = 54
x = -3.375
Substitute with the value of x in equation I to get y as follows:
y = 2(3.375) = -6.75
Therefore, for the given system of equations:
x = -3.375
y = -6.75</span>
Answer:
Step-by-step explanation:
9x+8x+5+11= 17x+16
-5x-2x-7+6= -7x-1
-x-5x-9-4= -6x-13
3x-x-4+7= 2x+3
7x-5x+4-5= 2x-1
2x+7x-3+11= 9x+8
-4x+6x-5-8= 2x-13
12x-2x-14-3= 10x-17
5x-5x+4-12= -8
Hope this helps (brainliest is appriciated)
