1. storing milk at temperatures colder than 35°f can affect its quality of taste. however, storing milk at temperatures warmer than 40°f is an unsafe food practice. which of the inequalities below represent the union of these improper storage temperatures, t, in degrees fahrenheit? a. t > 35 or t < 40 b. t < 35 or t > 40 c. t > 35 and t < 40 d. t < 35 and t > 40 2. what are the solution(s) to the absolute value equation below? 15| x-7|+4=10|x-7|+4 a. x= - 5\7 or x = 5\7 b. x=5 or x= -5 c. only x=7 d. x= 7/5 or x= -7\5 3. match the absolute value equation with the statement that describes the solutions to that equation. a. two solutions b. solution c. no solution |x+1|+5=2 |4x+12|=0 |3x|=9

1.

Storing milk at temperatures smaller than 35°F can affect its quality of taste.

hence  t > 35°F

storing milk at temperatures greater than 40°F is an unsafe food practice. hence

t < 40°F

so correct choice is

C. t > 35 AND t < 40

2.

15| x-7|+4=10|x-7|+4

subtracting 4 both side

15| x-7|+4- 4 =10|x-7|+4 - 4

15| x-7| = 10|x-7|

this is possible when |x-7| = 0

hence x - 7 = 0

x = 7

hence correct choice is

C. only x=7

3.

|x+1|+5=2

we know that , |x+1| ≥ 0

adding 5 both side

|x+1| + 5 ≥ 0 + 5

|x+1| + 5 ≥ 5

hence the relation |x+1|+5=2  is false.

C. no solution

|4x+12|=0

4x+12 = 0

x = -12/4

x = - 3

hence B. solution

|3x|=9

3x = 9

x =  9/3

x =  3

hence  

A. two solutions

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
