The sum of 2 numbers is 30 yhe product is 176. what are yhe 2 numbers

jok3333 [9.3K]

According to the question,

$x +y=30~~~~......equation (1)\\xy=176~~~~........equation (2)\\\\Taking~equation~(2),\\ xy=176\\\\y = \frac{176}{x}\\\\Now, ~substuting~the~value~of~y~in~equation~(1), ~we~get,\\\\x+ \frac{176}{x}=30\\\\ \frac{x^2+176}{x}=30\\\\x^2+176=30x\\\\x^2-30x+176=0\\\\x^2-8x-22x+176=0\\\\x(x-8)-22(x-8)=0\\\\(x-8)(x-22)=0\\\\Using~zero~product~property,\\\\Either, \\x-8=0\\x=8\\\\Or,\\ x-22=0 \\x=22\\\\When,\\x=8,\\\\(8)+y=30\\y=22 \\\\And~when,\\x=22\\\\(22)+y=30\\y=8\\ \therefore The~two~numbers~are~8~and ~22$

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remai

victus00 [196]

Answer:

zero

Step-by-step explanation:

The computation of the remainder when the number would be divided by 35

Let the number be x

So if x is divided by 5 gives the remainder 0

x = 0

And, if x is divided by 7 gives the remainder 0

x = 0

So if x is divided by 35 so the remainder is also zero

George has $23 to spend on art supplies. He wants to buy markers, paper, and glue. If the total cost of the markers and paper is

jeka57 [31]

Answer:

If Michael has $2 and he spends $1, how much money does he have left? We can figure this out by subtracting $1 from $2. This is obviously equal to $1.

We can use the same idea for this problem. George starts with $23 and spends at least $14. After this, George has 23 - 14 = $9 dollars left. So, George can spend $9 at the max.

We can translate this into math words by saying George can spend less than 9 on glue, so p < 9. So, a. is the correct answer.
