Use the equation 300⇒5x to find how much tim made each day on average.
x⇒60 so, Day 1: $60, Day 2: $70 etc.. so the equation 300=5x+10 suffices the problem. 300⇒5x+10 ⇒ 290=5x
x=58
So, Tim earned $58 his first day. Hope this helped.

Answer from: xdimplesjoon

The given problem is based on arithmetic sequence
Sn = 300 (the sum of money in five days)
d = 10 (the difference day by day)
n = 5
The question asks how much Tim earn on the first day, we write it as a₁

The general formula to find the sum of a sequence is
n/2 (2a₁ + d(n-1)) = Sn

Input the numbers to the formula to find the value of a₁
n/2 (2a₁ + d(n-1)) = Sn
5/2 (2a₁ + 10(5-1)) = 300
5/2 (2a₁ + 10(4)) = 300
5/2 (2a₁ + 40) = 300
2a₁ + 40 = 300 × 2/5
2a₁ + 40 = 120
2a₁ = 120 - 40
2a₁ = 80
a₁ = 80/2
a₁ = 40

The first day, Tim earned $40

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

Answer from: Quest

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
