Answer:

b. 36 years

Step-by-step explanation:

Today

Nirmala = x years

Rahul = 3x years

In 13 years

Nirmala = 3x + 13 years

Rahul = 2(x+13) - 1

3x + 13 = 2(x+13) - 1

3x + 13 = 2x + 26 - 1

3x + 13 = 2x + 25

3x - 2x = 25 - 13

x = 12

Nirmala = x years

= 12 years

Rahul = 3x years

= 3(12)

= 36 years

The age of Rahul today is 36 years

What is 4x+5 less than or equallys too 13 equals

gizmo_the_mogwai [7]

If you are trying to solve for x, then
4x+5<=13
subtract both sides by 5

4x<=8
then divide both sides by 4
x<=2

How do you use compatible numbers to estimate the quotient $595 divided by 25

storchak [24]

Well, 25 certainly doesn't divide evenly into 595, but it does divide into 600, which is very close to 595. So if we divide 600 by 25, we can get a rough estimate of what 595 divided by 25 is.
$\frac{600}{25} = 6* \frac{100}{25} = 6* 4=24$

What is the solution to the system of equations? (Hint: Use Substitution.)

Jet001 [13]

Answer:

(-1,9)

Step-by-step explanation:

y = -3x + 6

y = 9

-3x + 6 = 9

-3x = 3

x = -1

y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,

-3(-1) + 6 = 9

(-1,9)

Simplify. 2u? - 20u +42 u² – 5u+6

chubhunter [2.5K]

Answer:

The simplified expression is:

$\frac{2(u + 7)}{(u- 2)}$

Step-by-step explanation:

We want to simplify:

$\frac{2 {u}^{2} - 20u + 42}{ {u}^{2} - 5u + 6}$

We factor the numerator and the denominator to get:

$\frac{2(u - 3)(u + 7)}{(u- 2)(u- 3)}$

Cancel out u-2 which is common to the numerator and the denominator yo get:

$\frac{2(u + 7)}{(u- 2)}$
