The ratio of the number of Victor’s tools to the number of Ilya tools is 5:2. Victor has 42 more tools than Ilya. How many tools

AnnyKZ [126]

Answer: Victor should give 28 tools to Ilya.

Step-by-step explanation:

Since we have given that

Ratio of the number of Victor's tools to the number of IIya's tools = 5:2

Let the number of Victor's tools be 5x

Let the number of Ilya's tools be 2x

According to question, Victo has 42 more tools than Ilya.

So, our equation becomes,

$5x-2x=42\\\\3x=42\\\\x=\dfrac{42}{3}=14$

So, number of tools Victor has 5x=5×14=70

Number of tools Ilya has 2x = 2× 14 =28

Let the number of tools that Victor should give to Ilya be 'y' so that the ratio of the number of victor's tools to the number of Ilya's tools is 3:4.

According to question, it becomes,

$\dfrac{70-y}{28+y}=\dfrac{3}{4}\\\\4(70-y)=3(28+y)\\\\280-4y=84+3y\\\\280-84=3y+4y\\\\196=7y\\\\y=28$

Hence, Victor should give 28 tools to Ilya.

How would you write a word phrase for the algebraic expression d/5+2? The difference between the quotient of d and 5 and 2? The

krek1111 [17]

Answer: The word phrase for this expression is the last option, "The sum of the quotient of d and 5 and 2." d is being divided by 5, so we would use "quotient of d and 5" for that part, and then we would add the "sum" because d/5 is being added to 2.
