Answer: -3 + 4 = 1
==================================================
Explanation:
We start at the bottom layer.
That arrow on the bottom layer goes from 0 to -3. In short, it represents the number -3.
The upper arrow moves from -3 to +1 or simply 1. This is a distance of 4 spaces. So we add on 4.
Overall, this diagram represents -3+4 = 1
We use letters to substitute for unknown numbers. I hope this helps. :)
D. 4/5. Just have to figure out what is left. so 5/5-1/5=4/5
Rewriting this <span>7-y=5x+11 in standard form involves only changing the order in which the terms appear:
</span><span>7-y=5x+11 becomes 5x + y + 11 - 7 = 0, or 5x + y + 4 = 0, or 5x + y = -4.</span>
Answer:
6
Step-by-step explanation:
Let "a number" = x
44 = 8x - 4
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 4 to both sides:
44 (+4) = 8x - 4 (+4)
44 + 4 = 8x
48 = 8x
Isolate the variable, x. Divide 8 from both sides:
(48)/8 = (8x)/8
x = 48/8
x = 6
6 is your answer.
