Answer:
1.80
Step-by-step explanation:
He spent 1.20 on the gum in total. 3.00-1.20=1.80

Answer:</h2>
Using the distributive property, we can simplify the expression.
4 × 3 = 12
4 × = 1
4 × = -2
Here is the simplified expression:
Since the temperature keeps increasing by 2°F each hour for the next 7 hours, the graph will be a straight line graph.
Let T be temperature
t be the time at temperature T
At t₁ = 0, T₁ = 43°F
At t₂ = 1, T₂ = 45°F (temperature increase by 2°F)
Using the straight-line formula to get the equation of the graph. The equation is expressed as T = mt + b
- m is the slope
- b is the intercept
Get the slope
Get the intercept
Substitute m = 2 and the coordinate (0, 43) into the expression
43 = 2(0) + b
43 = b
b = 43
Get the equation of the line
T = 2t + 43
Graph the equation of temperature over time
