Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Step-by-step explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

x ≥ -2
Step-by-step explanation:
Answer:
Option D. 9
Step-by-step explanation:
There are two ways to obtain the answer to the question.
Method 1:
Let 2x + 1 = 0
Making x the subject, we have
2x + 1 = 0
Collect like terms
2x = –1
Divide both side by 2
x = –1/2
Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:
4x³ – 6x² – 8x + 7
x = –1/2
4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7
4(–1/8) – 6(1/4) – 8(–1/2) + 7
–1/2 – 3/2 + 4 +7
– 4/2 + 4 + 7
– 2 + 4 + 7
= 9
Method 2:
Divide 4x³ – 6x² – 8x + 7 by 2x + 1

y=-1
4[-1]+1
-4+1=-3
-3 is your answer.
Step-by-step explanation:
<em>→</em><em> </em><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>4</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em>
<em>→</em><em> </em><em>3</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>3</em><em> </em><em>-</em><em> </em><em>4</em><em> </em><em>=</em><em> </em><em>9</em>
<em>→</em><em> </em><em>x </em><em>=</em><em> </em><em>9</em><em>/</em><em>3</em><em> </em><em>=</em><em> </em><em>3</em>
<em>→</em><em> </em><em>x </em><em>=</em><em> </em><em>3</em>
<em>option</em><em> </em><em>B </em><em>is </em><em>correct</em>
