I only know 23
6x-4 x=4-6=-10
4x+24 x=24-4=20
So! 20-(-10)=10 or 30 because you change the sign with this rule
if the sign are the same you keep change, change. which means keep 20 change - to + and change - to +, so then it becomes 20+(+10)
Convert 150mm into cm = 15cm
So 15cm to 60cm
Divide by 15
B. 1 to 4
Answer:
2.5% and 2.5 · 10^-3, 0.25, 2/5, √5
Step-by-step explanation:
0.25, 2/5, 2.5 · 10^-3, 2.5%, √5
Now let's list them all in the same form, why not decimals.
0.25 = 0.25
2/5 = 4/10 = 40/100 = 0.4
2.5 · 10^-3 = 2.5 · 0.01 = 0.025
2.5% = 0.025
√5 ≅ 2.236
It’s ether 138.6 or 101.4. 123 rounded to the nearest tenth is 120 so you ether add or subtract
