5(9-4)2-3^2 -3^2=9
5(9-4)2+9 9-4=5
5(5)2+9 5(5)=25
(25)2+9 (25)2=50
9+50=59
The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4
<h3>How to write and solve equation?</h3>
let
x = cost of the meal
Both = 2x - 3
- Jessica = 3/4x
- Callista = 1/2x
3/4x + 1/2x = 2x - 3
(3+2)x / 4 = 2x - 3
5/4x = 2x - 3
5/4x - 2x = - 3
(5-8)x/ 4 = -3
-3/4x = -3
x = -3 ÷ -3/4
= -3 × -4/3
= 12/3
x = $4

Answer:
Step-by-step explanation:
First, let us notice that the ticks on the side of this quadrilateral indicate that the lengths of the sides are equal.
From this, we can create the following equation based on the perimeter of this shape.
Now, we can solve this equation for x by first combining like terms
Now, we can subtract 56 from each side
And now divide each side by 2
Just to check out answer, we can plug this x-value into our original perimeter equation to see if it is correct
Answer:
2hr 48 minutes
Step-by-step explanation:
65t + 85t = 420
150t = 420
t = 2 120/150 = 2 4/5 = 2hr 48 minutes
