Answers
10 x 9 x 8 = 720
9514 1404 393
Answer:
120
Step-by-step explanation:
We assume the order of the toppings does not matter. Then the number of interest is the number of combinations of 10 toppings taken 3 at a time. That is given by ...
10C3 = C(10, 3) = 10!/(3!(10 -3)!) = 10·9·8/(3·2·1) = 120
120 different 3-topping pizzas can be made if 10 toppings are available.
_____
Additional comment
If order matters, then 10 choices can be made for the first topping, 9 for the second, and 8 for the third, for a total of 10×9×8 = 720 different pizzas.

Solve by elimination Solve by elimination or substitution: 4x + 2y = 6 and x - 3y = 5
Answers
Step-by-step explanation:
since we need to multiply only one equation with something, elimination might be a good method here. we bring both equations to 4x terms and then subtract the second from the first equation :
4x + 2y = 6
- 4x - 12y = 20
-----------------------
0 14y = -14
y = -1
=> e.g. in the second original equation
x - 3×-1 = 5
x + 3 = 5
x = 2

Dan received 64 dollars for his birthday. He went to a sporting goods store
and bought a baseball glove, baseball, and bat. He had 31 dollars left over,
how much did he spent on the baseball gear?
Answers
Answer:
the answer is 33 bucks because you have subtract the 64 -31 =33
We can create an Algebraic equation to represent the scenario. The variable “x” is equal to how much of his birthday money he spent.
64-x=31 [Equation]
64-64-x=31-64 [Subtract 64 from both sides to cancel it out and isolate x]
-x=-33 [Simplification after subtraction]
-x/-1=-33/-1 [Divide by -1 on both sides to cancel it out and solve for x]
x=33 [Defined Variable]
*Recall that “x” is equal to his expenses.
Therefore, Dan spent $33 of his $64.
We can check this because 64-33=31.
