3a) Answer: 84 degrees
Step-by-step explanation:
3x + 2(x+20)= 180 (total sum of angles in a triangle is 180 degrees)
5x+40 = 180
5x = 140
x= 28
3x= 28 x 3
= 84
1) Since there are 16 ounces in a pound you multiply 16 by the number of pounds. So 6x16=96 then add the extra ounces and your answer is 100 oz.
2) Seth finished faster because she finished in 24 second, since there are 3 feet per yard, you multiply 3x200=600, then, you divide 600 feet by 25 feet and you get 24. So Seth finished in 24 seconds
Answer:
D)
Step-by-step explanation:
f(x) = x^2 -14x -72
0=x^2 - 14x-72
0=x^2 - 18x+4x-72
0=x(x-18)+4(x-18)
0=(x-18)(x+4)
x-18=0 or x+4=0
x1=18 or x2=-4
asis of symmetry: x=(x1+x2)/2
x=(18+(-4))/2
x=14/2
x=7
(3*15)+(17*15)=45+255=300
the final answer is 300
or 20 fifteens
