b² - 121
Step-by-step explanation:
(b +11)(b - 11)
b² - 11b + 11b - 121
b² - 121
Let’s say Peter’s number is P.
P minus 16 and the answer times -2 is -34
-2(P-16) = -34
-2P+32 = -34
-2P = -66
Divide by -2
P is 33.
Check: 33-16 is 17 and 17*-2 is -34. So
P is 33.
1/4th of Mai’s height is equal to 2/5th of Jon’s height
Let 'x' represent Mai's height and 'y' represent Jon's height.
Therefore, 1/4th of "x" should be equal to 2/5th of "y". This gives us the following equation :
(1/4)x = (2/5)y
multiply both sides by 4/y
x/y = 4*(2/5)
x/y = 8/5
x:y = 8:5
The ratio of Mai's s height to Jon's height is 8 to 5
