I think it’s 1/12 exactly you have a one in 12 chances of rolling a 5
Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
Answer:
0.761
Step-by-step explanation:
first you do 3 divided by 2.2 and get .733 which you round to .7
next you do 3 divided by 2.28 and get .76
last you do 3 divided by 2.283 and get .761
Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
Answer: 25 gr. of 60% salt solution.
32 kiwi = $16 Divide by 16 on both sides
2 kiwis = $1 Multiply times 4 on both sides
8 kiwis = $4
Hope that helps you
