A.
Let x = age of Samantha.
Then x - 2 = age of Emily,
and x + 2 = age of Lauren.

b.
x - 2 + x + x + 2 = 42

c.
x - 2 + x + x + 2 = 42

3x = 42

x = 14

x - 2 = 14 - 2 = 12

x + 2 = 14 + 2 = 16

The ages of the sisters are 12, 14, 16.

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.

<u>Total number of tickets sold:</u>

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

<u>Simplified expression:</u>

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 $29t+45$

SOME ONE PLEASE HELP WITH THIS MATH QUIZ PLASE HONEST AWNSERS!!!

Liula [17]

Answer:

1. d 2. d 3. a

Step-by-step explanation:

1. factor

((w-4)(w-6))/((w-5)(w-6))+8/(w-5)

solve

(w-4)/(w-5)+8/(w-5)

(w+4)/(w-5), so d

2.factor

((b+2)(b-4))((b+2)(b-1))-6/(b-1)

solve

(b-4)/(b-1)-6(b-1)

(b-10)/(b-1), so d

3. (2/5t-3/3t)/(1/2t+1/2t)

(2/5t-1/t)/(2/2t)

(2/5t-1/t)/(1/t)

t(2/5t-1/t)

2/5-1=-3/5, so a
