The answer is 55 I know this because 5 + 5 is 10 and 5 - 5 is 0. Therefor the answer is 55. HOPE THIS HELPS!
One step equation, where only one step is required to solve the problem. Example:
20 = 5x
4 = x
Fractions:
1/2 + x = 3/2
x = 3/2 - 1/2
x = 1
Decimals:
0.5 + x = 1.5
x = 1.5 - 0.5
x = 1
Real world problem: (word problem and equation)
It costs $5 per hour to rent a canoe plus a $3 rental fee. How much will the total be if you plan on renting the canoe for 3 hours?
y = 5x + 3
y = total cost ; x = number of hours rented
y = 5×3 + 3
y = 15 + 3
y = $18

Answer should be t=-2h+21.
Step-by-step explanation:
General format of a linear equation can be given as,
y= mx + c
Where,
y ⇒ dependent variable ( in this case temperature t)
m⇒ Gradient ( the rate at which the temperature drops)
x⇒ independent variable ( hours )
c⇒ intercept ( this is the starting temperature)
Now we can substitute the given values to the above format to arrive at the equation,
t=-2h+21
There is no correct answer given.
The solution is (3,2) cause both of the lines intersect at one point (which is a solution),and that point is (3,2) :)
