Answer:
10 x -6y = -76
-56 - 10x - y = -76
10x - 6y = -76 (-56) - (-76) = 20
-10 x -y = -20
10x - 6y = -76
-10x -y =-20
10x cancels
76 + 20 = 96
-7y = - 96
divide both sides by -7
y = 96/7
substitute into -10x - y = - 20
- 10x - 96/7 = - 20
96/7 is a fraction btw
= -10 x = - 20 + 96/7
-20 + 96/7
-10 x = -44/7
divide by - 10
x = 22/ 35 ( a fraction)
(x,y) = (22/ 35) ( 96/7)
Answer:
2x=1
Step-by-step explanation:
Use x for "a number"
x times 2 = 1
2x=1
which solves for 0.5 or 1/2
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)

It would have taken you 5:30 for each mile. 55/10 is 5.5 thats 5 and a half, half a minute is 30 seconds. so 5 minutes and 30 seconds
