Answer:
82
Step-by-step explanation:
triangle adds upto 180 degrees
180 - (53+45) = 98
Then two lines adapt to 180 degrees
therefore, 180 -98 = 82
Answer:
148
Step-by-step explanation:
=1332÷9
=148
45% of 40 is 0.45×40=18 girls
if x girls join then 56% of 40+x is 0.56(40+x)=18+x
22.4+0.56x=18+x
put together like terms
4.4=0.44x
<span>x=10 girls joined</span>
A. 12•8=96, 96/2=48, 48•4=192, 12•12=144, 192+144=336
