Question

PLEASE HELP ME!!!!!!!!!! 57-4t >(their is an egual sign under the less then sign)13
A. t<=-15
B. t<=15
C. t<=11
D. t=>-11

Answer 1

57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11

u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.

Answer 2

Work: 57-4t>/13
Solve for t
-57 both sides
-4t>/-44
÷-4 both sides
Flip sign since you are dividing by a negative
T < / 11
Answer: t < / 11
Check your work: 10 is less than 11 plug in 10
57-4 (10)>/13
57-40>/13
17>/13
The answer is correct
