Answer:
If what I think youre saying is correct, then it should be 1/9
Step-by-step explanation:
4/15 + (-7/45)
Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.
12/45 + (-7/45)
As the fraction on the right side is negative, it is taken away from the left fraction, hence:
(12 - 7)/45
Therefore, with simple subtraction,
5/45
Simplify to 1/9
Answer:
A) 12 toppings.
Step-by-step explanation:
That would be the answer if there are no combinations of toppings.
You would simply take the number of sizes (3) and the number of toppings (4) and multiply them together to get 12 combinations.
Answer:
Divisible by 3 is the answer
Step-by-step explanation:
First get everything to have the same base of 5
25^11 - 5^19
(5^2)^11 - 5^19
5^(2*11) - 5^19
5^22 - 5^19
Now factor out the GCF 5^19 to get
5^22 - 5^19
5^(19+3) - 5^(19+0)
5^19*5^3 - 5^19*5^0
5^19(5^3 - 5^0)
5^19(125 - 1)
5^19*(124)
At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4
Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4
Since 31 is a factor of the original expression, this means the original expression is divisible by 31.
Answer:
Step-by-step explanation:
You add the 4 to both sides of the equation.
