Mary draws the number line below to represent the solution set of the inequality 50 – 8t < 90. What mistake did Mary make? Use the drop-down menus to explain your answer.

Picture relating to question is attached below

t > - 5

Line is in the wrong side

Step-by-step explanation:

Given the inequality :

50 – 8t < 90

-8t < 90 - 50

-8t < 40

-8t / - 8 < (40/ - 8)

t > - 5 (sign changes)

During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
