gregori [183]

Answer/Step-by-step explanation:

Let x = 4 (you and 3 friends)

Ticket cost per head = $5.50

Drink cost per head = $2.50

Popcorn cost per head = $4.00

<em>Expression representing total amount of money spent = $5.50(x) + $2.50(x) + $4.00(x)</em>

<em />

Evaluate the expression by plugging in the value of x = 4

Total amount of money spent = $5.50(4) + $2.50(4) + $4.00(4)

= $22 + $10 + $16 = $48

<em>Total amount of money spent = $48</em>

babunello [35]

Answer:

Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters

Use the three steps to solve the problem.
Ilia_Sergeevich [38]

Answer:

17

Step-by-step explanation:

Let d be dimes

q represent quarters

d = q + 10

10d + 25q = 345 cents

Substitute for "d" and solve for "q";

10(q+10) + 25q = 345

35q + 100 = 345

35q = 245

q = 7

Since d = q+10, d = 17
