Answer:
.85
Step-by-step explanation:
Start at the end.
The 5 makes the 7 an 8, which makes the 8 an 9, which makes the 4 a 5.
Answer:
x = -4
Step-by-step explanation:
3x + 5 = x - 3
Subtract x from each side
3x+5-x = x-3-x
2x+5 = -3
Subtract 5 from each side
2x+5-5 = -3-5
2x = -8
Divide each side by 2
2x/2 = -8/2
x = -4
Answer:
x=2
Step-by-step explanation:
3x+17=14x-5 so...
22=11x (subtract 3x and add 5 to both sides)
2=x (divide both sides by 11)
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4
Hope this helps :)
