Hey there! :) So 7 weeks = 49 days, right? In order to get 49, you do 7(weeks) x 7(days per week) and get 49. Now, we compare. 49 < 52. 52 is greater.
Hope it helps! :D Have a great evening!
a. one solution
b. two solutions

Answer:
4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,
Step-by-step explanation:
B. 4d + $13.00 – $6.00 = $13.20; $1.55
C. 4d + $13.00 – $6.00 = $13.20; $1.60
D. 3d + $13.00 – $6.00 = $13.20; $2.07
If John and 3 friends ordered pizza for $13.00 and they paid $13.20 where in they also used the $6.00 gift certificate. Then we can deduce that the total amount of the bill was $13.20 + the gift certificate which is $6.00 which is equal to $19.20 and since the pizza was for $13.00 then we can deduct this from the total bill to get the amount of the drinks, ergo $19.20 - $13.00 = $6.20 since there were 4 large drinks so we divide the total amount of the drinks to the number of drinks. We would have $6.20 / 4 = $1.55 / large drink.
So the answer would be:
B. 4d + $13.00 – $6.00 = $13.20:$1.55
In order to prove the sentence 2/5 + 4/10, a partitioned model could be used. Here, 2/5 equates to 4 out of 10 parts and 4/10 equates to 4 out of 10 parts. Adding these provides a total of 8 out of 10 parts, thereby proving the sentence is true.
To prove the number sentence 2/5 + 4/10 is true using a partitioned model, you need to start by understanding that fraction addition involves just combining the fractions. If you partitioned a model into 10 equal parts representing 1 whole, 2/5 would be 4 parts and 4/10 would be 4 parts. Adding these together 4parts (being 2/5) + 4parts (being 4/10) makes 8 parts. Since 1 whole is made up of 10 parts, 8 parts equate to 8/10 or 0.8. Therefore, 2/5 + 4/10 = 0.8 or 8/10 validating the sentence as true.
