The sum of two integers equals twelve, while their product equals thirty-five. Which two numbers are they?

My name is Ann [436]

Answer: 5 and 7

Step-by-step explanation:

Given

Sum of the integers is 12

Product of the integers is 35

Suppose the integers are $x$ and $y$

$\Rightarrow x+y=12\\\\\Rightarrow y=12-x\\\Rightarrow xy=35\\\text{Substitute y}\\\Rightarrow x(12-x)=35\\\Rightarrow 12x-x^2=35\\\Rightarrow x^2-12x+35=0\\\Rightarrow x^2-7x-5x+35=0\\\Rightarrow (x-7)(x-5)=0\\\Rightarrow x=5\ or\ 7$

$\therefore \text{y can be }7\ or\ 5$

Hence, the numbers are 5 and 7.

5. If I multiply a number by 3 and then subtract 4, the result is the same as twice the number. Find this number.

Lina20 [59]

Answer:

4 is the number.

Step-by-step explanation:

Take the missing number as x,

→ (x × 3) - 4 = (x × 2)

→ 3x - 4 = 2x

→ 3x = 2x + 4

→ 3x - 2x = 4

→ [ x = 4 ]

Hence, the number is 4.

Wittaler [7]

Answer:

6*10^-3 > 5*10^-3

Step-by-step explanation:

$6*10^{-3}\\6*\frac{1}{10^{3} }\\6*\frac{1}{1000}\\\frac{6}{1000}=\frac{3}{500}=0.006$

$5*10^{-3}\\5*\frac{1}{10^{3} }\\5*\frac{1}{1000}\\\frac{5}{1000}=\frac{1}{200}=0.005$

0.006>0.005, therefore, 6*10^-3>5*10^-3
