IJ=x-4
JK=5x+12
IK=9x-19
IJ+JK=IK
(x-4)+(5x+12)=(9x-19)
x-4+5x+12=9x-19
6x+8=9x-19
6x+8-6x+19=9x-19-6x+19
27=3x
3x=27
3x/3=27/3
x=9
IJ=x-4=9-4→IJ=5
JK=5x+12=5(9)+12=45+12→JK=57
IK=9x-19=9(9)-19=81-19→IK=62
Answer: Option B. IJ=5, JK=57, IK=62
Answer:
1 dimes and 9 quarters
Step-by-step explanation:
9 quarters = 2.75
1 dime = 10c
all together equals 2.85
The expression that is equal to -4 is D 16/-4 which means option D is correct. ( it should be noted that option D is not written properly)
<h3>Why is that 4 is equals to 16
/-4?</h3>
In a mathematical expression when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.
In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence expression that is equal to -4 is 16/-4 which is means optionD is correct.
Therefore, option C is correct.
