Answer:
79+94+91+92+test5)/5=90
The lowest score have to be 94
Step-by-step explanation:
Our goal is gona be to have an average of 90, it can be higher but we are going to use this.
For average the equation is
(test1+test2+test3+test4+test5)/5=average
We know the result for the first 4 tests
Test 1=79
Test 2=94
Test 3=91
Test 4=92
But we dont know test 5
(79+94+91+92+test5)/5=average
Our goal for the average is 90
(79+94+91+92+test5)/5=90
79+94+91+92+test5=90*5
test5=450-79-94-91-92
Test5=94

x>4 or x<2
| 2x+5 | >0.5
:
x > −2.25 or x < −2.75
| 0.2x+3.5 | > 1.7:
x > −9 or x < −26
| x+3 | <1:
x < −2 and x > −4
| 2x+5 | <0.5
x < −2.25 and x > −2.75
| 0.2x+6 | <0.15
x < −29.25 and x > −30.75
