Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=

Shalnov [3]

ANSWER

$(25\times9)+(75\times9)=9(25+75)$

$(25\times9)+(75\times9)=9(100)$

$(25\times9)+(75\times9)=900$

EXPLANATION

According to the distributive property,

$(a\times b)+(a\times c)=a(b+c)$

This implies that,

$(25\times9)+(75\times9)=9(25+75)$

$(25\times9)+(75\times9)=9(100)$

The Right Hand Side of the equation now has 2 factors.

We solve now to obtain;

$(25\times9)+(75\times9)=900$

A driver driving a business trip of 240 miles would have reached his destination if he'd been able to drive 12 mph faster than h

mariarad [96]

The average speed of his trip is = 12 mile/ hour

The total distance covered by the driver = 240 miles

The rate at which he traveled = 12 miles per hour

Therefore, the time he used to cover his distance

= 240/12

= 20 hrs

But average speed = distance/ time

= 240/ 20

= 12 miles/ hour

Therefore, the average speed of his trip is = 12 mile/ hour
