Use the distributive property to write each expression as an equivalent expression 6x(3x+5y-4)

1 answer:

8 0

$6x \times 3x = {18x}^{2}$

$6x \times 5y = 30xy$

$6x \times - 4 = - 24x$

So, the equivalent expression is

{18x}^{2} + 30xy - 24x

Answer:

<em>4a ) Difference ⇒ $ 63.24,</em>

<em>4b ) 4 children</em>

Step-by-step explanation:

4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;

y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,

y = 42.16 + 85.15 ⇒ Combine like terms,

y = 127.31

If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;

y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,

y = 105.4 + 85.15 ⇒ Combine like terms,

y = 190.55

Difference; 190.55 - 127.31 = 63.24,

<em>Solution; Difference ⇒ $ 63.24</em>

4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;

169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,

21.08x = 84.32 ⇒ Divide either side 21.08,

x = 4 children

<em>Solution; 4 children</em>

On a bicycle, Miranda rides for 4 hours and is 50 miles from her house. After riding for 6 hours, she is 74 miles away. What is

Vera_Pavlovna [14]

<h2> Miranda's rate is 12 hours per mies.</h2>

Step-by-step explanation:

Given by question,

Miranda began her ride from home merely that she was 50 miles away from home after 4 hours of riding.

To find, Miranda's rate = ?

2 hours later she was 974 miles from home.

∴ 2 hours she rode = 74 miles - 50 miles

Miranda rides 24 miles in 2 hours.

∴ Miranda rides in 1 hour = $\dfrac{24}{2}$ $\dfrac{miles}{hour}$

= $12$ $\dfrac{miles}{hour}$

Thus, Miranda's rate is 12 hours per mies.
