"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
Answer:
if you mean 15k as is 15 thousand then the answer would be 15,010
Answer:
In mathematics, there are some properties of numbers that are handy to know. For example, the identity property of multiplication says that any number times one is equal to the original number. So, according to that property 5 x 1 = 5.
Step-by-step explanation:
Answer:
The first number should be a number between 1 and 10 (see explanation)
Step-by-step explanation:
For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.
36.5 is not between 1 and 10, alternatively, you can rearrange it:
3.65 x 10^7 <----This would be the correct scientific notation
It’s d bec each x has one input
