Answer:
Here you go
Step-by-step explanation:
(3 x 10) x 8 = x(10 x 8)
What you do the distributive property so multiply 3x10 and you get 30 and multiply by 8 you get 240 so one side is solved. Now multiply 10x8 you get 80 and remember to multiply the variable x so you get 80x=240 now divide 80 both sides and you will get 3 as your total answer
y=2x-0.5
Step-by-step explanation:
Given the expression of Δy in terms of Δx as;
Δy=4/2 Δx
Given y=2.5 and x =1.5 then substituting in the equation above will give;
y-2.5=2(x-1.5)
y-2.5=2x-3
y=2x-3+2.5
y=2x-0.5
