Answer: Ellen: 4t + 3s = 41.73
Danielle: 3t + 5s = 56.02
t = $3.69 each
Step-by-step explanation:
with 4t + 3s = 41.73 and 3t + 5s = 56.02
you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get
-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get
11/5t = 8.118 then divide 8.118 by 11/5 to get
t = 3.69

A sailboat and catamaran are in a race to see who can sail across the Atlantic ocean the fastest..
.The sailboat covers a distance of 3240 miles in 8 days
.The catamaran covered a distance of 4020 miles in 10 days
If the sailboat is able to maintain a constant rate for 10 days, how many more miles would they have traveled than the catamaran?
Answer:
The sailboat would cover 30 more miles than the catamaran.
Step-by-step explanation:
To find how many miles the sailboat goes in 1 day (unit rate) you divide 3240/8 that gives you 405 miles in one day. Multiply that by 2 to get 810 miles in two days. Add 810+3240=4050. That shows that in 10 days the sailboat would travel 4,050 miles which is 30 miles more than the catamaran.
The inequality x ≥ 25 can be used to represent the distance an athlete runs each week, where x is the distance in miles.
Which of these statements best describe the distance run by the athlete each week?
1. The distance is more than 25 miles.
2.The distance is no more than 25 miles.
3.The distance is at least 25 miles.
4.The distance is less than 25 miles.

Answer:
D. (43 +60) +40
Step-by-step explanation:
The purpose of changing the grouping in addition problems is to simplify the mental effort required as much as possible. This will generally mean grouping ...
"complementary" numbers, numbers with the same number of leading or trailing zeros, numbers with the same sign, and fractions with the same denominator.AnalysisA. Numbers ending in 0 are already grouped; no change is needed.
B. Fractions with the same denominator are already grouped; no change is needed.
C. Numbers with the same (negative) sign are already grouped; no change is needed.
D. Numbers ending in zero could be grouped to make addition easier:
43 +(60 +40) . . . . regrouping would be useful
We also note that in A and D, the sum of numbers ending in zero is 100, so these numbers are "complements" of each other. This is another reason for grouping them together.

A block of cheese is in the shape of a rectangular prism with a width of 2.5 inches and a height of 5 inches. The volume of the block of cheese is 75 cubic inches. What is the length of the block of cheese?
Answer:
The formula for volume is l x w x h.
Step-by-step explanation
To find the missing link, we do the equation backwards.
l x 2.5 x 5 = 75
If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.
To check, do 5 x 2.5 x 6 which should equal 75
6 is your length

In 24 weeks Amanda earned $4,924 selling cars. She earns the same amount of money each week. Let “n” stand for the amount she earned each week. How much money does Amanda earn in one week?
explain how you got your answer 9basically put the work in the explanation
Answer:
Let's assume that Amanda earns the same amount of money each week, and we'll represent that amount as "n".
We are given that in 24 weeks, Amanda earned a total of $4,924. We can set up an equation to represent this information:
Total earnings = Amount earned per week * Number of weeks
$4,924 = n * 24
To find the amount Amanda earns in one week, we need to solve for "n". We can do this by dividing both sides of the equation by 24:
$4,924 / 24 = n
To calculate this, we can use a calculator or perform long division:
n ≈ $205.17
Therefore, Amanda earns approximately $205.17 in one week.

Find an ordered pair , x y that is a solution to the equation. 5x-y=9
Answer:
(1, -4)
Step-by-step explanation:
In order to find a solution to a linear equation, we can substitute any value for one variable, simplify the equation, and find the value of the other variable to find a solution that is an ordered pair.
Since any value for either variable will do, we can choose something simple, such as 1. I chose to substitute 1 for x into the equation, as seen below.
[tex]5x-y = 9\\5(1)-y = 9[/tex]
Now, all I need to do is solve and isolate y:
[tex]5(1)-y = 9\\5-y = 9\\-y = 4\\y =-4[/tex]
So, with this linear equation, when x equals 1, y equals -4. Thus, a solution to the equation is (1, -4).
3.14 x 60^2 x 30
