Answer:
<h2>-11 and 1</h2>
Step-by-step explanation:
Put the values of x to the given expression:
for x = -3:
2(-3) - 5 = -6 - 5 = -11
for x = 3
2(3) - 5 = 6 - 5 = 1
Answer:
ok so
Step-by-step explanation:
8x + 7 + 7x - 2=90=>
=> 15x+5= 90
=> 15x=90 - 5=>
=> 15x =85= x= 5.6666...
of students only saw jewelry collection
<em><u>Solution:</u></em>
Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs
7/8 of the students saw either the jewelry collection or the dinosaurs
<em><u>To find: Fraction of students only saw jewelry collection</u></em>
From given statement,
Fraction of students saw dinosaur = 
Fraction of students saw either the jewelry collection or the dinosaurs = 
Therefore,
Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur
Thus of students only saw jewelry collection
The answer to this question is 2
this is because it is the highest before it starts to turn into fractions and square roots.
I hope this helps!!!!!
