Given that:
<span>22a(22b)=16
484ab=16
thus
ab=16/484
ab=4/121
thus given that
ab=4/121
then
a=4 and b=1/121
hence
4+1/121
=4 1/121</span>
2(x + 3) = x - 4
distribute
2x + 6 = x - 4
either subtract 6 from both sides or add 4. i will be subtracting 6.
2x = x - 10
subtract x from both sides
x = -10
Answer:
Maria is 66" tall, Juan is 51" tall
Step-by-step explanation:
There are 12 inches to a foot.
Luis is 62" tall
Maria is 1/3 of a foot taller than Luis, 1/3 of 12 is 4, (multiply 12 by 1/3)
So Maria is 4 inches taller than Luis, making her 66" tall
Juan is 1 1/4 feet shorter than Maria, that's one foot and 1/4 of a foot shorter, 1/4 of 12 is 3 (multiply 12 by 1/4)
So Juan is one foot (12 inches) plus 3 more inches shorter than Maria,
Juan is 15 inches shorter than Maria, making him 51" tall
