You are selling tickets to a play. You have sold (3t+2) tickets for $5 each and (2t+5) tickets for $7 each. Write an expression

aliya0001 [1]

Given that the number of tickets that are sold for $5 is (3t+2) tickets.

The number of tickets that are sold for $7 is (2t+5) tickets.

We need to determine the expression that represents the total number of tickets sold and the simplified expression.

Total number of tickets sold:

The expression for (3t+2) tickets sold for $5 is given by

$5(3t+2)$

The expression for (2t+5) tickets sold for $7 is given by

$7(2t+5)$

The expression for the total number of tickets sold is given by

$5(3t+2)+7(2t+5)$

Thus, the expression that represents the total number of tickets sold is $5(3t+2)+7(2t+5)$

Simplified expression:

We need to simplify the expression $5(3t+2)+7(2t+5)$

Hence, let us multiply the terms within the bracket.

Thus, we get;

$15t+10+14t+35$

Adding the like terms, we have,

$29t+45$

Thus, the simplified expression is $29t+45$

Find the surface area.

denpristay [2]

Step-by-step explanation:

a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.

while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :

top and bottom

left and right

front and back

all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.

your remember, the area of a rectangle is

length × width

in our case we have

top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²

left and right : 2.5×5 × 2 = 12.5×2 = 25 in²

front and back : 11.5×5 × 2 = 57.5×2 = 115 in²

so, the total surface area of the whole block is

57.5 + 25 + 115 = 197.5 in²
