Find out the determinant
we have
2x-y=4
3x+y=1
so
D=(2)(1)-(-1)(3)
D=2+3
D=5
therefore
<h2>the answer is the second option</h2><h2>Verify</h2>
solution (1,-2)
equation 1 -------> 2(1)-(-2)=4 -------> 4=4 is true -----> is ok
equation 2 ------> 3(1)-2=1 -----> 1=1 ----> is true -----> is ok
C.
4 (x+7) = 38 represents the tape diagram correctly.

Answer:
24 inches
Step-by-step explanation:

Answer:
-1/23x+-1.043478261
Step-by-step explanation:
Distribute -1/23 to x and 24
-1/23 times x equals -1/23x
-1/23 times 24 equals -1.043478261
So -1/23(x+24) = -1/23x+-1.043478261
