Jack and Luke were wrapping presents. Jack was able to wrap presents at a constant rate of 3 presents every 15 min. Luke was able to wrap presents at a constant rate of 5 presents every 20 min. Each boy had 20 presents to wrap, and the boys started wrapping presents at the same time.Write an equation to find the rate each boy wraps presents. You may use y=kx or w=rt (4 points 2 for each)
Answers
Answer 1
Answer:
jack = 3 presents every 15 minutes luke = 4 presents every 20 minutes target = 20 presents wrapped per person
y = kx ; where k is the constant rate, x is the number of presents wrapped, y is the total number of minutes spent wrapping x number of presents.
we need to compute for the unit rate of each individual.

Let the variable s represent the amount Trey saved before mowing lawns.
Trey earns s dollars. Then he earns an additional $40. So far, he earns (s+40). Then this amount is doubled: 2(s+40) At the end, he has $234. So the equation is 2(s+40) = 234 2s + 80 = 234 2s = 154 s = 77
An arithmetic approach (solving using addition) could have the equation as (s+40) + (s+40) = 234 s + 40 + s + 40 = 234 2s = 154 s = 77
Which is greater -4 4/25 or 4.12?
Answers
the answer would be 4.12 because the other one is a negative
4.12 because it is a positive number. If both are negative then it would be the first one.
Difference between 645 and 738
Answers
when someone asks about the difference between two numbers, they are asking you to subtract one number from the other. This sentence can also be written as:
738 - 645 = ?
The answer therefore is 93
Hi,
I'm not sure if you want to find the DIFFERENCE between 645 & 738 or 738 & 645. So Below I have done both of them below:-
645 - 738 = -93
If someone gave you 645 candies, and then someone else said you better give me 738 candies. So, in the end you would have -93 candies left.
738 - 645 = 93
If someone gave you 738 candies, and then someone else said you better give me 645 candies. So, in the end you would have 93 candies left.
Hope I helped:P

A is the answer as (-4,8), (2,6), and many others are also possible solutions.
The correct answer is A, i think because y = 12 and x= 4, 4×3=12, and you can switch any numbers like y = 24 and x = 8, it fits the equation.
If sin x=−4/5, and π
Answers
Answer:
Step-by-step explanation:
sin x=−4/5
x=sin^-1(4/5)
x=about 53.1
x=(-4/5)/sin(53.1 degrees)=about -2.64662408617
