For 2, work backwards. 93.34 divided by 18.69 equals what? That’s your E.
3, use multiplication. 4.30 times 8.60 equals your D.
4, you just do as the problem says.
5, you do the same as number 2.
6, you do the same as 3.
For the word problem, say how someone starts off with 51.15 and has to give that something to 5 people.
Answer:
Step-by-step explanation:
(-5, 7) ⇒ x₁ = -5, y₁ = 7
(10, 1) ⇒ x₂ = 10, y₂ = 1
So the slope:
5% sales tax, because the total would be $42 and if you multiply 40 x 0.05 (the equation for tax) you get 2 and that is the amount of tax they charged you
a proportion is an amount of something compared to another, for example:
1 : 2
or
3 : 6
hope this helps
