Answer:
132 and 88
Step-by-step explanation:
If there are 20% more boys than girls, then this means that the total percentage of boys us 60% and girls is 40%.
0.6 * 220 = 132
0.4 * 220 = 88
There are 132 boys and 88 girls in year 9
Distribute the signs: 12-14+9x
so, -2+9x
Answer:
M<2= 65
Step-by-step explanation:
The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.
You would use angle addition postulate to find the answer so M<1 + M<2 = 180.
Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180
Then you would subtract 115 from 180 in which you would get M<2 = 65
