Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
Answer:
15.6 ft
Step-by-step explanation:
Since the sails are similar then the ratios of corresponding sides are equal.
Comparing the shortest sides, that is
10 : 6 = 5 : 3
let the longest side be x, then using proportion
=
( cross- multiply )
5x = 78 ( divide both sides by 5 )
x = 15.6
The longest side is 15.6 ft
Answer:
x = a³b + b²/ab + 1
Step-by-step explanation:
x = a² + b²/ab + 1
x = a² × (ab + 1) + b²/ab + 1
x = a³b + a² + b²/ab + 1
x = a³b + b²/ab + 1
Answer:
725
Step-by-step explanation:
30 - 1 = 29
29 x (25/1) = 725
