Answer:
a = (b + c)/(bx - 1)
Step-by-step explanation:
Given
x= (a+b+c)/(ab)
Solving for a
x = (a + b+ c)/(ab)
abx = a + b+ c
abx - a = b + c
a(bx - 1) = b + c
a = (b + c)/(bx - 1)

Mr. Rozario bought some oranges and some apples. The ratio of oranges to apples is 2:5. He gave 3/4 to his sister and 34 oranges to his brother. He now has a ratio of 2:3. How many oranges and apples did he buy?
Answer:
He bought 544 oranges and 1,360 apples
Step-by-step explanation:
Here, we want to know the number of oranges and apples bought
Let the number of oranges be x and the number of apples be y
Looking at their ratios;
x:y = 2:5
so;
x/y = 2/5
2y = 5x ••••••(i)
Now, he lost 3/4 of the apples ( by giving out)
What would be left with him is (1-3/4) = 1/4 * y = 0.25y
What is left with him out if the oranges will be; x-34
So now;
0.25y/x-34 = 2/3
3(0.25y) = 2(x-34) •••••••(ii)
From i, y = 5x/2 = 2.5x
Putting this into ii above, we have
3(0.25)(2.5x) = 2x - 68
1.875x = 2x-68
2x-1.875x = 68
0.125x = 68
x = 68/0.125
x = 544
But y = 2.5x
y = 2.5 * 544 = 1,360
What is the unit rate?
Will give brainliest
Answer:
1 week 2 inches
Step-by-step explanation:
Pretty self explanatory
so we started with 4cm and by week 3 its 10cm.
So since the 4cm doesn’t count toward the 10 cm since it was already there, that turns it into 6 becuase 10-4 is 6. So 3 weeks, 6 inches, find the unit rate by dividing 6 and 3 and you’ll get 2, so 2 inches every week, now to check they gave us another week which is by 6 weeks, its 16 cm tall, now remember to subtract the 4, so 12, 12/6=2. So 2 inches every week.
DOUBLE CHECK:
So 6 weeks in total, thats 12cm becuase each week is 2cm 6*2=12. Add the 4 from the beginning, it’s 16
TRIPLE CHECK
make equation:
X for growth each week
6*x+4=16
You’ll get 2
this is math practice work, and I don’t quite understand it :< hellppppp
According to the given Statement:
1. - 4 x - 6 = -24

Laurel is a huge fan of hats, she likes all kinds of hats and recently started collecting them. She already owns 3 hats. She plans on buying a hat according to the season every month. Based on this information answer the following Questions.
What is the linear function?
Answer:
y=3+x
Step-by-step explanation:
If you are ever unsure about how to proceed with a math problem, one thing I find very helpful is to imagine the scenario and sub in the numbers. That's always helped me
At the very beginning, when
x=0, Laurel hasn't bought any new hats yet, she owns 3 hats, so y=3.
After the first month, when x=1, laurel owns 3 hats, plus the 1 hat she just bought. She now owns y=3+1 hats.
After the second month, when
x=2, laurel owns 3 hats, plus the 2
new hats she bought after she started collecting hats. She now owns y=3+2
hats.
Now, we can write the function.
y=3+x
Declan is moving into a college dormitory and needs to rent a moving truck. For the type of truck he wants, Company A charges a 30$ rental fee plus $0.95 per mile driven, while Company B charges a 45$ rental fee plus $0.65 per mile driven. For how many miles is the cost of renting the truck the same at both companies?
Both companies will charge the same cost for renting the truck for 50 miles.
Given that
Declan is moving into a college dormitory and needs to rent a moving truck.
For the type of truck he wants, Company A charges a 30$ rental fee plus $0.95 per mile driven,
Company B charges a 45$ rental fee plus $0.65 per mile driven.
To find
How many miles is the cost of renting the truck the same at both companies?
So, according to the question
we have,
Charges of company A
For rent = $30
For drive = $0.95 per mile
Total cost charges by company A = 0.95(The total distance traveled by truck) + 30
Charges of company A
For rent = $45
For drive = $0.65 per mile
Total cost charges by company A = 0.65(The total distance traveled by truck) + 40
Let's assume The total x miles distance traveled by truck is produced same cost for both companies.
So, we can say that
Total cost charges by company A = Total cost charges by company B
Now, putting the all given values
We will get,
0.65(x) + 45 = 0.95(x) + 30
0.65x + 45 = 0.95x + 30
0.95x - 0.65x = 45 - 30
0.3x = 15
x = 15/0.3
x = 50
At 50 miles is the cost of renting the truck the same at both companies

grace and her dad are planning to attend the state fair. an adult ticket is $15. the price of an adult ticket is the price of a student ticket plus $8. write an equation to determine how much grace will pay for a student ticket. x 8
Grace will pay $7 for a student ticket.
Let's write the cost of a student ticket as "S." The price of an adult ticket, according to the information provided, is equal to the cost of a student ticket plus $8. Therefore, this relationship can be expressed as an equation:
Price of adult ticket = Price of student ticket + $8
Since the price of an adult ticket is $15 and the price of a student ticket is "S," the equation becomes:
$15 = S + $8
We now need to separate "S" on one side of the equation in order to figure out how much Grace will pay for a student ticket ("S"). To accomplish this, take $8 away from either side of the equation as follows:
$15 - $8 = S
$7 = S

square root of a number is the factor that we can multiply by itself to get that number.
The square root symbol is also called as a RADICAL.
Perfect squares are the squares of the integers also called as square numbers.
to find the square root of non-perfect squared numbers we have to check the number with a near-perfect squared numbers
how to find square root of non perfect squared numbers:
If we can't figure out what factor multiplied by itself will result in the given number, we can make a factor tree.
Factor tree of 32 = 2*2*2*2*2
= (2*2) * (2*2) *2

the coordinates of the figure with the given coordinates after the transformation on the plane.
preimage: J(-3, 0), K(-2, 4), L(-1, 0)
image: triangle QRS, translation of JKL along the vector(5, -4)
We need to know about translation along vector to solve the probelm. The coordinates of the figure after translation along the vector (5,-4) are (2,-4), (3,0) and (4,-4).
Translation means moving an object from one place to another. Every point on the object moves the same amount of distance and in the same direction. Translation of a point along a vector means moving the point to a different location with respect to the given vector. Here we have three points which form a triangle JKL, we have to translate triangle JKL with respect to the vector (5,-4) to get triangle QRS. Inorder to translate a point along a vector we add the x-coordinate of the vector to the x-coordinate of the point and same for the y-coordinates.
J (-3,0) Q (-3+5,0-4)≡(2,-4)
K (-2,4) R (-2+5,4-4)≡(3,0)
L (-1,0) S (-1+5,0-4)≡(4,-4)
Therefore we get the coordinates of triangle QRS after translation of triangle JKL along vector (5,-4) to be (2,-4), (3,0) and (4,-4)
