multiply first equation by -2 and add to 2nd equation
-4x-6y=4
<u>4x+7y=-6 +</u>
0x+1y=-2
y=-2
sub back
2x+3y=-2
2x+3(-2)=-2
2x-6=-2
2x=4
x=2
(x,y)
(2,-2)
C.The second integer is greater than the first integer

Answer:
<u>B</u> because if you divide each fraction you get 8.7.
Answer:
n ≤ 4
Step-by-step explanation:
"The difference between a number and seven is less than or equal to -3" translates into n - 7 ≤ -3. To solve, isolate the variable n.
n - 7 ≤ -3
n ≤ -3 + 7
n ≤ 4
Machine A:
60 / 10 = 6 - 10 minute segments per hour
7 x 6 = 42 - parts per hour
42 x 12 = 504 - parts made on Monday
Machine B:
60 / 15 = 4 - 15 minute segments per hour
16 x 4 = 64 - parts per hour
64 x 10 = 640 - parts made on Monday
504 + 640 = 1144 - parts made by the two machines on Monday
Hope this helps!! :)
