Answer:
.
Step-by-step explanation: The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.
The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.
(2.5 x 10⁻⁸) x (9 x 10⁻¹⁰)
= (2.5 x 9) x (10⁻⁸ x 10⁻¹⁰)
= (22.5) x (10⁻¹⁸)
= 2.25 x 10⁻¹⁷ .
Answer:
The answer is
for p<5
F(p)=50-p(12.25)
Step-by-step explanation:
First we stablish that 4 is the maximun number of pizzas he can buy as
50/12,25 = 4,08
then we know that he will receive change iqual to the original amount he has less the number of pizzas he buy multiplied for the cost of each pizza.
