Answer:
The first number is 3
The second number is 7
Step-by-step explanation:
Let x = the first number
Let y = the second (other) number
<em>One number added to three times another number is 24</em>:
x + 3y = 24
Make 3y the subject by subtracting x from both sides: 3y = 24 - x
<em>Five times the first number added to three times the other number is 36:</em>
5x + 3y = 36
Substitute 3y = 24 - x into 5x + 3y = 36 and solve for x:
5x + (24 - x) = 36
5x + 24 - x = 36
Combine like terms: 4x + 24 = 36
Subtract 24 from both sides: 4x = 12
Divide both sides by 4: x = 3
Substitute found value of x into x + 3y = 24 to find y:
3 + 3y = 24
Subtract 3 from both sides: 3y = 21
Divide both sides by 3: y = 7
Răspuns:
125%
Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
Answer: ![7170+2890x](https://tex.z-dn.net/?f=7170%2B2890x)
Step-by-step explanation:
Given
Editor gets a raise of
each year
In her eighth year, she is making ![\$27,400](https://tex.z-dn.net/?f=%5C%2427%2C400)
Eighth years refers to 7 complete year
Suppose she starts with an amount of P
So, her pay after x years is
![\Rightarrow P+2890x](https://tex.z-dn.net/?f=%5CRightarrow%20P%2B2890x)
for the eighth year i.e. ![x=7](https://tex.z-dn.net/?f=x%3D7)
![\Rightarrow P+2890\times 7=27400\\\Rightarrow P=27400-20230=\$7170](https://tex.z-dn.net/?f=%5CRightarrow%20P%2B2890%5Ctimes%207%3D27400%5C%5C%5CRightarrow%20P%3D27400-20230%3D%5C%247170)
after x years it is
![\Rightarrow 7170+2890x](https://tex.z-dn.net/?f=%5CRightarrow%207170%2B2890x)
