To solve this equation, you need to use the distributive property. You first multiply 3 and a and you get 3a. Then you multiply 3 and -1 and you get -3. You add -3 to 34 which is 31. Then you divide 31 by 3 and you get 10.3. Unfortunately. I have no idea how to explain why backtracking helps you solve the equation but I hope this helps you a little bit.
Answer:
approx 23.35 degrees
Step-by-step explanation:
Work backwards: 48" is 48/60 minute, or 0.8 minute. Then we have
23 degrees 20 minutes 0.8 minute, or
23 degrees 20.8 minute, or
23 degrees 20.8/60 degree, or
23.347 degrees, or
approx 23.35 degrees
Answer:
16
Step-by-step explanation:
1/2 (perpendicular height × base)
1/2(4×8)
2×8
=16
2(2x^2-3) -5
4x^2 - 6 - 5
4x^2 - 11
g(x) = 2x - 5
If you had to evaluate g(3)
You would substitute 3 in for the x and simplify. Instead of substituting a single number you are substituting the binomial
2x^2 -3 and then simplifying. I hope you understand.
Answer:
.03472
Step-by-step explanation:
take sell price $20. subtract cost of 11.32 which equals 8.68. then divide 8.68 by the sell price $20
The formula for contribution margin is the sales price of a product minus its variable costs. In other words, calculating the contribution margin determines the sales amount left over after adjusting for the variable costs of selling additional products.
