Step-by-step explanation:
Let's assume
Mark's present age is x
so, his age 2 years ago will be
Marks age, X is six times his age 2 years ago
so, we will get equation as
.............Answer
5x - 3y = 9
5x = 9 + 3y
5x - 9 = 3y
( 5x - 9 ) / 3 = y
y = ( 5 / 3x ) - ( 9 / 3 ) ( I just split the common denominator to individual parts )
y = 5 / 3x - 3
Answer:
b ≈ 148.5
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan68° = =
Multiply both sides by 60 to clear the fraction
60 × tan68° = b, thus
b ≈ 148.5 ( to 1 dec. place )
