Wei is writing out expressions from verbal descriptions. He writes "multiply two by the difference of n and three" as 2(n - 3) ) He writes "subtract one from the sum of n and six" as 1 - (n + 6) . He writes "add five to the product of four and n”as 5 + 4x n Complete the statements . Wei made a mistake when writing as an expression. The correct way he should have written the expression is

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
