Answer:
6
Step-by-step explanation:
because you list the prime factors of each number then multiply those factors both numbers have in common
Step-by-step explanation:
3.5 hours for 1 cake means 3.5 hours per cake.
similar : 2 hours for 1 pie means 2 hours per pie.
so, if there are e.g. 3 pies, they take 3×2 = 6 hours.
therefore the general constraint is
3.5x1 + 2x2 <= 70
I think the names "x1" and "x2" are confusing when writing this inequality.
I prefer to use x and y.
and then it would look like
3.5x + 2y <= 70
Answer:
D.
Step-by-step explanation:
1) the domain is x∈[0;+∞);
2) the solution is:
3) finally, the solution with the domain is:
x∈[0;100].
Answer:
When squaring a number it is essentially taking a number and multiplying it by itself. For example, 5^2 is 5×5 (=25).
