Step-by-step explanation:

Given : If you multiply a number by 3 and then subtract 5, you will get 40.

To find : what is the number.

Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.

According to question :

Let the number = x

Multiply is with 3 = 3x

Subtract 5 from it we get 40 .

3x -5 = 40

On adding both sides by 5

3x = 45 .

On dividing both sides by 3

x = 15.

Therefore, Number = 15.

vovangra [49]

Answer:

$(3y^2-5)(y^2+1)$

Step-by-step explanation:

Let's see if we can think of two numbers that multiply to be 3(-5)=-15

andd add up to be -2

How about -5 and 3? That work's! :)

$3y^4-5y^2+3y^2-5$

Factor by grouping!

$y^2(3y^2-5)+1(3y^2-5)\\(3y^2-5)(y^2+1)$

Divide. Write the quotient in lowest terms. 4\dfrac{2}{3} \div 7 =4 3 2 ÷7=4, start fraction, 2, divided by, 3, end fraction,

velikii [3]

Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

Given the quotient: $4\dfrac{2}{3} \div 7$

Step 1: Write $4\dfrac{2}{3}$ in improper fraction.

$4\dfrac{2}{3}=\dfrac{14}{3}$

Therefore:

$4\dfrac{2}{3} \div 7=\dfrac{14}{3} \div 7$

<u>Step 2:</u> Change the division sign to multiplication by taking the reciprocal of 7

$\dfrac{14}{3} \div 7 =\dfrac{14}{3} X\dfrac{1}{7} \\$Simplify\\\\=\dfrac{2}{3}$
