Rewrite the expression by using grouping symbols

Elan Coil [88]

Answer:

D) $y(5+a)$

Step-by-step explanation:

Given expression:

$y\times5+y\times a$

The above expression can be rewritten using grouping symbols by using properties of equality.

We apply distributive property of multiplication according to which:

$ab+cb=b(a+c)$

the product of a number and each addend individually added together is equal to the product of that number and sum of the addends.

So, we can write

$y\times5+y\times a=y(5+a)$

Find the x-intercept and y-intercept of the line. <br> 3x + 5y = −15

insens350 [35]

Answer:

The x intercept is (-5,0)

The y intercept is (0,-3)

Step-by-step explanation:

To find the x intercept we set y=0 and solve for x

3x+5y = -15

3x+0 = -15

3x = -15

Divide by 3

3x/3 = -15/3

x = -5

The x intercept is (-5,0)

To find the x intercept we set x=0 and solve for y

3x+5y = -15

0+5y = -15

5y = -15

Divide by 5

5y/5 = -15/5

y = -3

The y intercept is (0,-3)

The density of concentrated sulphuric acid is 1.8 g/cm.calculate the volume of 3.1 kg of the acid

Sphinxa [80]

Step-by-step explanation:

$density = \frac{mass}{volume} \\ volume = \frac{mass}{density} \\ changing \: 1.8 {gcm}^{ - 3} to \: {kgm}^{ - 3} \\ multiply \: by \: 1000 \\ = 1800 {kgm}^{ - 3} \\ volume = \frac{3.1}{1800} \\ = 0.00172 {m}^{ 3}$
