2 number lines. there isn't a simpler answer.
Compatible numbers are close to actual numbers, but easier to solve.
So instead of: 326 : 44,
we will do: 320 : 40 = 8
And we know that the real result is:
326 : 44 = 7.4
Answer:
B ) 320 divided by 40 is 8.
Y-25 = 8x+25-25
-25/8 = 8x/8
x = -25/8 or -3.125
Our missing number we are solving for is X.
We are told x will equal 2x (number doubled) plus -16.
x = 2x + -16 We want to move the smaller variable to the right to sit with the larger one and move the -16 to the left by subtracting it from both sides. Remember that subtracting a negative is the same as adding it. So essentially we add 16 to both sides.
16 = 2x - x Combine the variables
16 = x or x = 16
I chose to put the variable on the left in this problem to avoid having a -x on the left side. It doesn't matter which side the variable is on to solve, but when you state it - we usually say x = 16.
Answer:
w = -7z/2
Step-by-step explanation:
Our goal is to isolate w
1. subtract 3w from both sides to get 2w+9z = 2z
2. Subtract 9z from both sides to get 2w = -7z
3. Divide both sides by 2 to get w = -7z/2
We cannot simplify further, so this is our answer.
