Solve the equations
Y=2x-4, 3x+y=1
Step-by-step explanation:
[tex]y = 2x - 4[/tex]
[tex]3x + y = 1[/tex]
[tex]y = 1 - 3x[/tex]
Equating,
[tex]2x - 4 = 1 - 3x[/tex]
[tex]2x + 3x = 1 + 4[/tex]
[tex]5x = 5[/tex]
[tex]x = 1[/tex]
Placing it,
[tex]y = 1 - 3( 1)[/tex]
[tex]y = 1 - 3[/tex]
[tex]y = - 2[/tex]

Jasmine spends exactly £120 on three types of plants: poisoned ivy, deadly nightshade and triffids. Poisoned ivy plants cost £2 each, deadly nightshade plants cost £9 each and triffids cost £12 each. She buys twenty plants in total, including at least one of each type. How many triffids did she buy?
Answer:
9/5
Step-by-step explanation:
2×9×12=216 so216/120 =9/5
Jasmine bought approximately 4 triffids.
We have,
We know that Jasmine bought a total of twenty plants and that she purchased at least one of each type.
Let's assume she bought x triffids.
From the given information, we can determine the number of poison ivy plants and deadly nightshade plants she bought:
Number of poisoned ivy plants = Total plants - (Number of deadly nightshade plants + Number of triffids)
Number of poisoned ivy plants = 20 - (1 + x) = 19 - x
Number of deadly nightshade plants = Total plants - (Number of poisoned ivy plants + Number of triffids)
Number of deadly nightshade plants = 20 - (1 + (19 - x)) = 20 - (20 - x) = x
We can now set up an equation based on the total amount Jasmine spent:
Total cost = (Number of poisoned ivy plants * Cost per poisoned ivy plant) + (Number of deadly nightshade plants * Cost per deadly nightshade plant) + (Number of triffids * Cost per triffid)
£120 = (19 - x) * £2 + x * £9 + x * £12
Simplifying the equation:
£120 = £38 - £2x + £9x + £12x
£120 = £38 + £19x
£82 = £19x
Dividing both sides of the equation by £19:
£82/£19 = x
x ≈ 4.32
Since we can't have a fractional number of plants, we'll round down to the nearest whole number.
Therefore,
Jasmine bought approximately 4 triffids.

Step-by-step explanation:
a. We want to see when the two snakes will be the same length.
b. b1 + r1m= b2 + r2m where b is the initial length and m is the number of months and r is the growth rate
c. for the anaconda 5.23 + 1.27 m where m is the number of months, and the total length is in meters
The anaconda starts at 5.23 meters and grows 1.27 meters each month for m months
d. for the python 4.76 + 2.04m where m is the number of months, l is the length of the python in meters
The python starts at 4.76 meters and grows 2.04 meters each month for m months
e. 5.23 + 1.27 m = 4.76 + 2.04m m is the number of months Each side is the number of meters

Which of the following is a factor of 10x + 5?
A. 5
B. 10
C. х
D. 5x
Based on our analysis, options A and D are factors of 10x + 5. Therefore, the correct answers are: A. 5 and D. 5x
To determine which of the given options is a factor of 10x + 5, we need to check if the option can be divided evenly into 10x + 5.
Let's go through each option:
A. 5: Yes, 10x + 5 can be divided evenly by 5, as (10x + 5) ÷ 5 = 2x + 1.
B. 10: No, 10x + 5 cannot be divided evenly by 10, as 10 is greater than 10x + 5.
C. х (x): No, 10x + 5 cannot be divided evenly by x, as x is a variable and cannot be factored out completely.
D. 5x: Yes, 10x + 5 can be divided evenly by 5x, as (10x + 5) ÷ 5x = 2 + (1/x).
Based on our analysis, options A and D are factors of 10x + 5. Therefore, the correct answers are: A. 5 and D. 5x

Billy borrowed $400 from his friend Tommy to get his truck fixed. The next time he got paid, Billy paid Tommy back $100, then agreed to pay $25 a week until his debt was paid off. 1.Write a linear equation to represent the amount of money m Billy owes Tommy after w weeks. 2.How long will it take Billy to pay off his debt to Tommy?
Answer:
(400 - 100) / 25 = 12
Step-by-step explanation:
Billy gives Tommy 100, so we can subtract $100 from $400, giving us 300. Then to undertand how many weeks it will take Billie to pay Tommy, we divide 300 by 25, and get 12.

A small bus charges $3.50 per person for a ride from the train station to a concert.
The maximum capacity of the bus to carry the passengers is 10.
The minimum capacity of the bus to carry the passengers is 3.
Function B gives the amount of money that the bus operator earns when n people ride the bus.
Thus the value of 'n' is restricted between 3 to 10.

la edad de josé y beatriz están en la relacion de 5 a4 . si dentro de 3 años la suma de ambas edades seran 60 años , ¿ cual es la edad de beatriz ?
Answer:
La edad actual de Beatriz es de:
30 años
Step-by-step explanation:
Planteamiento:
5e = 4b
(e+3) + (b+3) = 60
e = edad actual de José
b = edad actual de Beatriz
Desarrollo:
de la segunda ecuación del planteamiento:
e + b + 6 = 60
e + b = 60 - 6
e + b = 54
e = 54 - b
sustituyendo este último valor en la primer ecuación del planteamiento:
5(54-b) = 4b
5*54 + 5*-b = 4b
270 - 5b = 4b
270 = 4b + 5b
270 = 9b
b = 270/9
b = 30
e = 54 - b
e = 54 - 30
e = 24
Comprobación:
5e = 4b
5*24 = 4*30 = 120
