Answer:
<h2>
x = 67°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is allways 180°
So:
x + 53° + 60° = 180° {subtract 113° from both sides}
x = 67°
Answer:
33
Step-by-step explanation:
simply replace x with 7!
7^2 = 49
49-16=33
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>
4500 times 5% per year for 3 years = (4500*.05)*3 = answer 1
4500 times 5% per year for 4 years = (4500*.05)*4 = answer 2
Answer 2 minus answer 1 = jackpot
