Answer:

Step-by-step explanation:
In this exercise, we want to model an equation to represent the cost that Gabriel will when registering with a gym.
from the given information, we can model the cost after the equation of a straight line
y= mx+c
so "C" is the cost, while $40 is a fee dependent on "t" the number of months subscribed
and $100 is the joining fee, which is a constant term

Answer:
369.5 ft²
Step-by-step explanation:
Separate the figure into 2 rectangles and 2 triangles.
(see attached image)
<u>Area 1</u>
Area of a rectangle = width × length
= 4 × 5
= 20 ft²
<u>Area 2</u>
Area of a rectangle = width × length
= 8 × (4 + 4 + 5)
= 8 × 13
= 104 ft²
<u>Area 3</u>
Area of a triangle = 1/2 × base × height
= 1/2 × (6 + 4 + 5 + 4 - 6) × 23
= 1/2 × 13 × 23
= 149.5 ft²
<u>Area 4</u>
Area of a triangle = 1/2 × base × height
= 1/2 × 8 × (21 + 8 - 5)
= 1/2 × 8 × 24
= 96 ft²
<u>Total Area</u>
Area 1 + Area 2 + Area 3 + Area 2 = 20 + 104 + 149.5 + 96
= 369.5 ft²
Answer: 105 chocolate bars
Step-by-step explanation:
The equation for this problem would be a=97-4*2
So, 97-4=93, and 4 * 2=8 so 93+8= 101
So he had 101 chocolate bars at first.
Answer:
22 is the answer
Step-by-step explanation:
Answer: 6 m
This statement:
"Jared has run two-thirds of an 18-kilometer race" can be written as an equation:

This means two-thirds of 18 km is equivalent to 12 km
If we substract this value to the total, we have the values of the kilometers left to run:

Therefore the correct option is D
