Together they swam a total of 175 laps. Swimmer B swam 25 more than twice as many laps as Swimmer A.
Answer:
75
Step-by-step explanation:
175= 25+2a
The number of laps that Swimmer A swam was 50 laps.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Let we suppose that:
Swimmer A swam x lapsSwimmer B swam y laps.Then, according to the given data, we have:
x + y = 175 laps
y = 25 + 2x (25 more than twice of laps of A is the number of laps of B).
Thus, we get a system of two equations as:
[tex]x + y = 175\\y = 25 + 2x\\[/tex]
From second equation, putting value of y in first equation, we get:
[tex]x + (25 + 2x) = 175\\3x + 25 = 175\\3x = 150\\\\x = \dfrac{150}{3} = 50 \: \rm laps[/tex]
As x is the number of laps Swimmer A swam, thus, the number of laps that Swimmer A swam was 50 laps.

3/4y+6=0 steps in order
Answer : y = - 8
3/4y+6=0
Step 1: Subtract 6 from both sides :
3/4y + 6 - 6 = 0 - 6
3/4y = -6
Step 2: Multiply both sides by 4/3 :
( 4/3 ) × ( 3/4y ) = ( 4/3 ) × ( -6 )
Final answer is y = - 8

The math problem is below
Answer:
Brooklyn earns four more dollars than Anna does each hour.
Step-by-step explanation:
So basically in order to get the amount ech of them recieve you would have to divide. So for Anna's since her least given number is 10 hours you would divide how much she earns (256) by how many hours she has been working (10) and you get 25.6
Now for Brooke she is given only one piece of evidence so you would use that she has been working for 26 hours and earns 769.6. So divide her earning by the hour and get 29.6
Subtract each of the answers (29.6-25.6) and you would get 4
Sorry if it doesn't make sense I was trynna rush and give you the answer

6. Monthly Mortgage payments can be found using the formula Below:
M-PG2)(1+1)"
(1+12"-1
M = monthly payment
P = amount borrowed
r=annual interest rate
n = number of monthly payments
The Ranallo family just bought a house. They qualified for an annual interest rate of 5.2% and their monthly payment
was $800 for a 30 year mortgage. Algebraically determine the amount of their loan to buy the house.
Answer: your equation is poorly written/wrong hence I used the equation below
answer : $289156.63
Step-by-step explanation:
applying the formula to calculate monthly repayment of Mortgage
M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ] ----- ( 1 )
M = Total monthly payment = 800 * 12 * 30 = $ 288,000
P = ?
r = 5.2% / 12 = 0.4%
n = 30 * 12 = 360 months
Back to equation 1
P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]
= 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]
= 288,000 / -0.996 = - $289156.63 ( It has a negative value because It is a loan borrowed )

sin 0 = 9/41. Find tan 0.
Answer:
B. 9/40
Step-by-step explanation:
just got the answer
The value of the tanθ is 9/40 after applying the Pythagoras theorem option (C) 9/40 is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a trigonometric ratio:
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
sinθ = 9/41
sin is the ratio of the side opposite to the hypotenuse.
From the Pythagoras theorem:
Adjacent side² = hypotenuse² - opposite²
Adjacent side² = 41² - 9²
Adjacent side = 40
tan is the ratio of the side opposite to the adjacent
tanθ = 9/40
Thus, the value of the tanθ is 9/40 after applying the Pythagoras theorem option (C) 9/40 is correct.

explain how to evaluate simplify and convert to radical form (x^3/8)^3/4
Answer:
[tex](x^\frac{3}{8})^\frac{3}{4} = \sqrt[32]{x^9}[/tex]
Step-by-step explanation:
Given
[tex](x^\frac{3}{8})^\frac{3}{4}[/tex]
Required
Convert to radical form
[tex](x^\frac{3}{8})^\frac{3}{4}[/tex]
Evaluate the exponents
[tex](x^\frac{3}{8})^\frac{3}{4} = x^\frac{3*3}{8*4}[/tex]
[tex](x^\frac{3}{8})^\frac{3}{4} = x^\frac{9}{32}[/tex]
Split the exponent
[tex](x^\frac{3}{8})^\frac{3}{4} = (x^9)^\frac{1}{32}[/tex]
Apply the following law of indices
[tex](x^a)^\frac{1}{b} = \sqrt[b]{x^a}[/tex]
So, we have:
[tex](x^\frac{3}{8})^\frac{3}{4} = \sqrt[32]{x^9}[/tex]

A grab-bag contains 30 packages worth $.65 each, 10 packages $.60 cents each, and 15 packages worth $.30 each. What is the expected value if you have to pay $.50 to pick one package at random?
Answer:
Expected value of package = $0.04 (Approx.)
Step-by-step explanation:
Given:
30 packages at $0.65 each
10 packages at $0.60 each
15 packages at 0.30 each
Pick up price for random one = $0.50
Find:
Expected value of package
Computation:
Total cost of 30 package = 30 x 0.65
Total cost of 30 package = $19.5
Total cost of 10 package = 10 x 0.60
Total cost of 10 package = $6
Total cost of 15 package = 15 x 0.30
Total cost of 15 package = $4.5
Total cost = 19.5 + 6 + 4.5
Total cost = $30
Cost of random package = 30 / [30+10+15]
Cost of random package = $0.54
Expected value of package = 0.54 - 0.50
Expected value of package = $0.04 (Approx.)

-3×4y = (4+5y)-72 answer fast with steps plz
Answer:
-12y=5y-68 true for all X
Step-by-step explanation:
-3x4y=(4+5y)-72
simplify:
-3x4y=12y
simplify:
(4+5y)-72
remove parentheses:
4+5y-72
subtract the numbers:
4-72= -68
=5y-68
-12y=5y-68
Answer:
the answer would be 4
Step-by-step explanation:
−3(4y)=4+5y−72
−12y=4+5y+−72
−12y=(5y)+(4+−72)(Combine Like Terms)
−12y=5y+−68
−12y=5y−68
Step 2: Subtract 5y from both sides.
−12y−5y = 5y−68−5y
−17y= −68
Step 3: Divide both sides by -17.
−17y -68
------------ = -----------
-17 -17

Answer:
18x^2 - 30x
Step-by-step explanation:
Distribution:
You just have to distribute 6x by each term in the parenthesis.
Equation: 6x(3x-5)
(You can also think of it as: 6x * 3x + 6x * -5)
18x^2 - 30x
This is as simplified as can it can be.
(You can’t add terms that have different variables, seeing as the first term has x^2 and the second one only has x).
