I can’t really see can you blow it up
Answer: 150
Step-by-step explanation:
30% = 0.3
100-30=70
70% = 0.7
0.7 X 500 = 350
500-350 = 150
Step 1; both side divide by 4, you'll get Ix-10I=8
step 2: x-10=8 or x-10=-8
x=18 or x=2
A question like this should be answered by first looking at the number and the numbers you are given and making an estimate, testing it, and repeating if it is incorrect. It is relatively simple and I would like you to at least try a couple of times with an estimate of your own. If you really do have trouble with this, I will put the answers in a second. To make sure you understand the concept I will answer 3 of the 4 and you can try the last one. I will also just state the number of steps and leave the most of the expression writing to you. ;)
A. 8 feet forward, 8 feet forward. 8×2 or 0 + 8 + 8
B. Probably the hardest. Good thing you get to do it :)
C. 6 feet forward, 5 feet forward. 0 + 6+5 or 0 + 5+6 (This shows the commutative property)
D. 8 feet forward, 5 feet back. 0 + 8 - 5 or 0 - 5 + 8.
(You Don't Need the 0's in any of them unless you are showing the starting point which you probably are required to do, but since technically the Cecil starts at 0, added the 0 as the point at which to start your expression.)
