X=36
you add 126 to 162 making it 288, then you minus 5 out of 13 making it 8. 288/8 =36
Answer:
12 pizzas were ordered and Maribel only has 108 dollars.
12x12=144, 144-108=36, meaning that Maribel needs 36 more dollars for the whole number of pizzas. She could only get 9 pizzas instead of 12 because 12x9=108.
Step-by-step explanation:
a negative times a negative = a positive
so (a * b) + c = 12
(-2 * -3) +6 = 12
6+6 = 12
For this case we have the following equation:

Where,
w: The weight of a spring in pounds
E: the energy stored by the spring in joules.
Substituting values we have:

Making the corresponding calculation:
Answer:
the approximate weight of the spring in pounds is:
