Answer:

18

Step-by-step explanation:

For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.

a = 2; b = 3

3ab

Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.

3ab = 3 * a * b

With this in mind, let's plug in the values of a and b into the expression.

3ab

= 3 (2) (3)

= 3 (6)

= 18

Hence, 3ab evaluated when a=2 and b=3 is 18.

Cheers.

Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen we
Phoenix [80]

<u>Answer-</u>

Set of constraints to model the problem are,

12x+9y\geq 510

y \leq 2x

y \geq 25

<u>Solution-</u>

<em>x = the number of lawns weeded by Gwen,</em>

<em>y = the number of dogs walked by Fabio.</em>

1.

As, Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog,

\text{Earnings of Gwen} = 12x

\text{Earnings of Fabio} = 9y

\text{Total earning} = 12x+9y

They need at least $510 to purchase the new gaming station, means they need $510 or more than $510.

The equation for this is,

12x+9y\geq 510

2.

The number of dog walks that Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed, means

y must be less than or equal to 2x.

The equation for this is,

y \leq 2x

3.

Fabio will walk at least 25 dogs, means y must be greater than of equal to 25.

The equation for this is,

y \geq 25
