Use proportions:
(7x-4)/31 = (4y+8)/24 = (y+2)/6
Multiply:
6*(7x-4) = 31*(y+2)---> 42x-24 = 31y+62 ---> 11y = 86, y = 86/11
I don;t like that is looks 'ugly', instead of sth like y = 88/11=8. I think 86/11 is the answer. Check the math! :)
7/22 you add the denominators toghether and add the numerators.
Answer:
15
Step-by-step explanation:
He learns 2 recipes a week. So divide 30 by 2 & get 15
The answer is between 17 and 18.
18 x 18 = 324
17 x 17 = 289
So it would be in between
Answer:
124.80 ft
Step-by-step explanation:
Height of Daniel = 6 ft
The angle of elevation from his eyes to the top of the statue is = 68°
Daniel is 48 ft away from the base of the statue
To find the height of the statue apply the tangent of an angle formula then add height of Daniel as;
Tan 68° = h/48
h= {48 tan 68°} + 6 ft
h= 124.804168964
h= 124.80 ft
