Answer:
150%
Step-by-step explanation:
The area is half base times height. We want the product to be the same, so if we scale one factor by f, we have to scale the other factor by 1/f to compensate.
Reducing by 60% is multiplication by f=1-60/100 = 0.4
So we have to multiply the height by 1/0.4=2.5 to compensate.
A factor of 2.5 is an increase of 150%
Check:
(1-60/100)(1+150/100) = 1, good
Answer: D 1881
Step-by-step explanation: 6889 and 1961 don't read the same forwards and backward. 1991 upside down is 1661. So, only 1881 works
Answer:
75.751=75 751/1000
Step-by-step explanation:
Answer:-3/4
Step-by-step explanation:
5x+2=x-1
5x-x=-1-2
4x=-3
X=-3/4
2y-2>-4+2. Add 2 to both sides. Now you have 2y>-2+2. Erm. I might be wrong since I JUST learned this unit and I made some mistakes. Ok soo, add 2 to both sides again. Now you have 2y+2>2. Subtract 2 from both sides. You now have 2y>0. You have no solution since 2 can't be divided by 0. I'm probably wrong but I hope I helped...ish.
