Answer: Y=4
Step-by-step explanation:
The diameter is the radius doubled. So, the radius CK is 2, so the diameter would be 4.
"Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week." because.
Let n be the number of aerobic and strength-training exercises per week.
Let x be the number of strength-training exercises per week on the beginner
15x + 20n = 90
Let y be the number of strength-training exercises for week on the advanced plan.
20y + 30n = 130
Multiply both sides by 1.5, to get:
22.5x + 30n = 135
Subtracting equation 2 from 3 we get:
22.5x - 20y = 5
Step-by-step explanation:
a.) the given term can be written as
=
=
=
hence the given term is
where b = 3
b.)
=
=
=
=
hence the given term is 12
Answer:
5/4 or 1.25
Step-by-step explanation:
-5/3 x -3/4
apply the fraction rule
-5/3 = 5/3
apply the same rule to -3/4
= 5/3 x 3/4
cross cancel common factor which is 3
and you will get 5/4
