The answer is 7/2 hope it helps
Answer:
See explanation.
Step-by-step explanation:
13. (4*5)/2 = 10
14. 5*7=35 7-3=4 8-5=3 (4*3)/2 = 6 35+6 = 41
15. 3*4 = 12
16. (4*4)/2 = 8 8*4=32 4*2=8 16*8=128 128-32 = 96
Let me know if you want me to better explain how I solved any of these.
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.
