Answer:
Current speed is 40mph
Step-by-step explanation:
We firstly need to know what is intended by upstream and downstream. When the boat travels in the direction of the current (horizontal movement of the water), we say it is moving downstream otherwise it is moving upstream.
Let's assume the speed of the boat is A and that of the current is B, then the speed when it moves dowstream would be A + B and the speed if it moves upstream would be A – B.
In this question, we know that the speed of the boat is 40mph. Given that it takes the same time to travel 8miles upstream as it does to travel 24miles downstream, we have
Speed upstream = 8/t
Speed downstream = 24/t
Respectively.
Let speed of current be X, then
Speed downstream = 40 + X
Speed upstream = 40 – X
From the question we have:
(40 + x)/24 = (40 – X)/8
(40 + x)/3 = (40 – x)/1
3(40 – x) = 40 + X
120 – 3x = 40 – X
120 – 40 = 3x – X
2x = 80
X = 40.
Therefore, current speed is 40mph

2b + 23 = 5b - 112 solved
Answer: b= 45
Step-by-step explanation:
Step 1: Subtract 5b from both sides.
2b+23−5b=5b−112−5b
−3b+23=−112
Step 2: Subtract 23 from both sides.
−3b+23−23=−112−23
−3b=−135
Step 3: Divide both sides by -3.
−3b /-3 = -135/-3

Gianna's family took a road trip. Gianna slept through the last 44% of the trip. If Gianna fell asleep after they had travelled 280 miles, what was the total length of the trip?
Answer:
500 miles
Explanation: 100-44 is 56, so 280 is equal to 56% of the trip. 280/56 is equal to 5. Therefore 5 is 1%, so if we multiply the 5 x 100 there we go, that's 100% of the trip. Not how your teacher told you to do it, but its the right answer.

We have the correct feet number (5) but the incorrect inches number (should be 3 inches and not 1/4 inches)
Step-by-step explanation:
Here, we want to make a conversion from feet to inches and feet
Mathematically, we know that;
1 feet = 12 inches
So, for 63 inches, we can have a clear ;
63/12 = 5 feet + 3 inches
Hence, the correct conversion of 63 feet should be;
5 feet and 3 inches

Plug in the point (1,6) into the inequality 4x-3y<12 to determine if the point is in the solution set. How do you know
A Yes, (1,6) is in the solution set because the truth value is TRUE
B No, (1,6) is not the solution because the truth value is FALSE
Answer:
false
Step-by-step explanation:
4(1) - 3(6)<12
4 - 18<12
12<12
so no the truth value is false 12 is not less than 12
Answer:
A. true
Step-by-step explanation:
If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.

Bridget is 5 years older than Angad. Paul is 4 years younger than Angad. If the total of their
ages is 49, how old is the eldest of them?
Answer: Bridge is 21 years old
Step-by-step explanation:
Ok so after reading the question I already know that B (Bridget), A (Angad) and P (Paul) is 49 in the sum of age. I also know that B=A+5 and P=A-4. After that I can assume B=P+5+4. So now after we gather everything, the age of all of them is the same if we delete 5, 4, 4 (From B=P+5+4 and P=A-4). 49-5-4-4=36. So now lets assume they are all 12 (36/3=12). B is 5 years older so lets add 5 to B. B=17, A=12 and P=8. 8+12+17= 37. We now know that but 37 is 12 under 49, so lets add the average 12/3=4 so we add 4 to all of them. B=21 A=16 P=12. 21+16+12=49. So Bridge is 21 years old, Angad is 16 years old and Paul is 12 years old
Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
Hakim received some gift cards for music and movie downloads for his birthday. Using one of them, he downloaded 20 songs and 13 movies, which cost a total of $163. Using another, he purchased 13 songs and 13 movies, which cost a total of $156. How much does each download cost?
Downloads cost $____for a song and $______ for a movie.
Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie
